The outdoor sauna experience is uniquely serene. Along with creating a relaxing and tranquil environment, the best home saunas for the outdoors can provide physical health benefits like improved muscle recovery1, reduced inflammation2, and better cardiovascular health3.
From high-quality infrared saunas to compact barrel saunas, portable profiles, and more, the Garage Gym Reviews team has researched and tested 30 saunas (and counting) to find the best outdoor sauna for fitness and recovery aficionados. Our squad consists of certified personal trainers, CrossFit Level 1 trainers, lifting coaches, and lifelong athletes. In short, we have the experience and expertise to provide expert recommendations on the best muscle recovery tools, saunas. We rated these outdoor saunas on a scale of 1 to 5 based on aspects noted in our fitness equipment testing methodology to find their overall score:
- Construction: We make sure the saunas are made from high-quality wood, such as hemlock, cedar, or aspen (all of which are the best woods for saunas). We also ensure there are no holes (aside from the purposeful ones used for ventilation). To earn a 3-out-of-5 rating or higher for construction, saunas should be built sturdy with minimal creaking and no air leaks.
- Performance: Perhaps the most critical factor is how long it takes each home sauna to get up to temperature and whether it holds temp until adjusted. A sauna will earn a 3 out of 5 or higher for performance if it heats up quickly and requires little to no adjustments to maintain the desired temperature.
- Features: Saunas should have an adjustable thermostat to determine and set the temperature. Models that display the temperature and allow users to adjust the levels to their liking will score at least a 3 out of 5 for features.
- Delivery and setup: Since saunas can be quite heavy and cumbersome, the delivery and setup process is particularly important. Does the manufacturer deliver the sauna curbside or offer to take it to your desired location? Are the assembly instructions easy to follow? Saunas that come with curbside delivery and have straightforward assembly processes that take less than three hours earn at least a 3-out-of-5 rating.
We also consulted with industry experts like quadruple-board-certified physician Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM, and Carolina Panthers assistant strength and conditioning coach Thomas Barbeau, CSCS, SCCC, to better understand the benefits of sauna therapy. In 2024, we helped nearly 500 people find their ideal home sauna, so read on to see which model belongs in your backyard or outdoor space this season.

Best Outdoor Sauna Overall: Sun Home Luminar Outdoor Infrared Sauna
Updated by: Stephen Sheehan, CPT, CNC
The Sun Home Luminar Outdoor Infrared Sauna has a sleek aesthetic to its design, while also being functional. One of the only infrared saunas that are able to be set up outdoors, this sauna has an exterior built from Grade-A carbonized wood to prevent warping, cracking, and shrinkage of the exterior. This sauna is a full-spectrum infrared sauna, providing near, mid, and far infrared heat in the sauna.
What our tester says:
“You can feel this sauna heat up in seconds—I really enjoy using it.”
At a Glance
- High-end, full-spectrum outdoor infrared sauna
- Average temperature range
- Requires a 240V outlet, which may require professional installation
- Below-average warranty
The Sun Home Luminar Outdoor Five-Person Full-Spectrum Infrared Sauna is a luxury model built with durability, performance, and convenience in mind. It features 15 heaters, carbonized all-weather wood, panoramic dura-glass panels, a mobile-app control system, Bluetooth surround sound, and medical-grade chromotherapy lighting. While its hefty price tag and lengthy assembly process may deter some potential buyers, the Luminar combines cutting-edge technology with excellent construction, helping it earn an overall rating of 4.3 out of 5 and the title of best overall outdoor sauna.

Why We Like The Sun Home Luminar Outdoor Infrared Sauna
Even with their increased popularity, infrared saunas are rarely made for outdoor use. However, that’s not the case with the Sun Home Luminar Outdoor Infrared Sauna. Featuring an aerospace-grade aluminum exterior and stainless steel roof, this sauna is built to endure the outdoors. GGR Everything lead reviewer Lindsay Scheele, CPT, CNC, rates the construction at 4.5 out of 5, stating, “Thankfully, the exterior is designed to withstand all seasons, so durability isn’t an issue—even in harsh climates.”
Along with a solid construction, the sauna is heated by an abundance of infrared heaters: five far-infrared heaters and 10 full-spectrum heaters. The infrared red sauna got to 160 degrees within 10 minutes, and while not as hot as dry saunas, it’s still an impressive temperature ( and heat rate) for the category. Lindsay scores the heat performance at 5 out of 5, adding, “You can feel it warming up almost instantly.”
Bluetooth connectivity made it super easy to stream podcasts, audiobooks, or music. You can make the space relaxing or turn it into a jam session.

Alternatives
Despite its attractive specs, the Sun Home Luminar Outdoor Infrared Sauna does have a few notable drawbacks. At nearly 1,300 pounds, this massive unit is anything but portable and requires professional hardwiring. Compared to other outdoor saunas we’ve tested, the setup is quite challenging, as well, resulting in a 3-out-of-5 rating for delivery and setup.
Furthermore, although it’s marketed as a five-person sauna, our testers found it a bit cramped when filled to capacity. “After having five actual people in it, we think it’s fairer to say it’s a four-person sauna,” Lindsay states.
Finally, as much as we love the build quality and features, the Luminar’s premium price tag of nearly $15,000 forced us to give a 3.5 out of 5 for value since it’s not the practical choice for every buyer—even those who want to enjoy all the benefits of infrared saunas.
If you don’t have the budget for the Luminar, consider the Redwood Outdoors Thermowood Cabin Outdoor Sauna, which seats four people for about half the cost.

Best High-End Outdoor Sauna: Plunge Sauna
Updated by: Stephen Sheehan, CPT, CNC
The Plunge Sauna is a versatile take on a traditional Finnish sauna. With a slanted back wall, the Plunge Sauna provides an ergonomic backrest to add comfort to your sauna session. Additionally, the benches fold up to allow more space for standing or stretching. The electric heater is able to let the sauna reach temperatures up to 230 degrees, according to the company.
What our tester says:
“Once it reaches the goal temperature, it holds it really well.”

- High-end indoor/outdoor sauna

If you’re looking for the best that money can buy, our favorite high-end option is the Plunge Sauna, by the creators of The Cold Plunge. This outdoor sauna comes with a unique modern construction—a slanted back wall with fold-away benches that can be tucked away for hot yoga or stretching. Plus, a HUUM stone heater can get this sauna to temperatures approaching 230 degrees. Although it’s quite expensive, this well-built, well-performing sauna earned a strong overall score of 4.1 out of 5, including a 4-out-of-5 value rating.
Construction: 5/5
Delivery & Setup: 3.5/5
Footprint: 3.5/5
Why We Like The Plunge Sauna
We like the unique design of the Plunge Sauna because it offers a modern take on a traditional sauna. A slanted back wall with an attached upper and lower bench provides an ergonomic backrest. The exterior and benches are constructed with incense cedar, providing an aromatic wood smell as well as protection against mildew and insects. This high-end outdoor sauna also has a waterproof roof, allowing it to work inside or outside your own home. We rate the construction a perfect 5 out of 5.
Although this isn’t the quickest sauna when it comes to heating up, we still rate the heat performance at 4 out of 5. Your patience will pay off, though, as the Plunge Sauna retains its temperature well. “It took 30 minutes for the sauna to cool back down after I had turned it off,” says our expert product tester.
The Plunge Sauna has a Wi-Fi controller that can be adjusted through a mobile app along with customizable accent lighting. Plus, if you want to stand or stretch in the sauna, you can flip the benches up—an innovative way to save and use space.
After spending some time in the sauna, I think it’d fit more like four people comfortably…maybe closer to three, depending on the size of the people.

During our testing experience, it took just under an hour for the sauna to go from 70 to 185 degrees. “I set the heat for my sauna session to 185 degrees and timed the process. Starting from 70 degrees, it took 56 minutes and 43 seconds to get to 185 degrees,” our product tester told me. While this length of time isn’t too long for a dry sauna of this size, it’s significantly longer than the warm-up time for the best infrared saunas—which are increasing in popularity.
Both the standard and extra-large versions of the Plunge Sauna will require a 240-volt outlet, and you should consult an electrician to install a dedicated outlet. In addition, while the parts are well-organized and the instructions are easy to follow, it’ll take about four people to put this sauna together.
“You need a lot of hands to hold large pieces together until you get all four outer walls assembled,” our tester explains, rating the delivery and setup at 3.5 out of 5. “We suggest at least four people to build this sauna, although six might be good, too.”
If you don’t need such a large sauna, you could opt for the Redwood Outdoors Duo Sauna—a two-person model that offers a good temperature range.
Testing Breakdown
The Plunge Sauna earned a rock-solid overall rating of 4.1 out of 5. Here’s a detailed scoring breakdown by category:
Vs. The Average
The Plunge Sauna is quite a bit more expensive than its competitors, but it’s also larger and can reach temperatures higher than any other sauna on our list.

Best Outdoor Steam Sauna: Redwood Outdoors Thermowood Cabin Outdoor Sauna
Updated by: Stephen Sheehan, CPT, CNC
Redwood Outdoors is a brand that offers a dozen different outdoor saunas. The Thermowood Cabin is the ideal choice for anyone looking for a four-person sauna that will offer a straightforward assembly with interlocking ultra-dry timber. The sauna features 2-level seating, which is the traditional Scandinavian design so you can choose between low- and high-heat options. The Thermowood Cabin comes standard with a Harvia electric heater, bucket and ladle, backrest, sauna rocks, and an internal light fixture.
What our tester says:
“Overall, I was impressed with how quickly it got hot in the sauna. It worked so well once we got it up and running. It kept the temperature and humidity where we wanted perfectly.”
At a Glance
- Traditional outdoor dry or steam sauna
- Heats up to 190° F
- Requires a 240V outlet for the heater
- Below-average one-year limited warranty
The Redwood Outdoors Thermowood Cabin Sauna is our choice for the best outdoor steam sauna thanks to its impressive performance and solid construction. This four-person sauna heats to 190 degrees Fahrenheit in just 35 minutes, earning a 5-out-of-5 performance rating. Whether it’s hot summers or cold winters, this model is built to last outside with its thermowood exterior, which is made from heat-treating Scandinavian softwood in kilns for multiple days. This process protects the wood from cracking or warping over time and makes it resistant to rot and fungi.
Heat Performance: 5/5
Footprint: 4/5
Value: 3/5
Why We Like The Redwood Outdoors Thermowood Cabin Outdoor Sauna
The Redwood Outdoors Thermowood Cabin Sauna is designed specifically to withstand the extremes of the outdoors. This sauna is airtight when built, as seen in its top-tier performance. GGR Everything lead reviewer Lindsay Scheele tested the Redwood Outdoors sauna and was highly impressed with its ability to reach the desired temperature efficiently.
“It worked so well once we got it up and running,” Lindsay says. “It kept the temperature and humidity where we wanted perfectly.”
We also appreciate that this four-person sauna features two-level seating, which is the traditional Scandinavian design. This allows you to choose between low- and high-heat options. Earning a 4-out-of-5 footprint rating, the Thermowood Cabin comes standard with a Harvia electric heater, bucket, ladle, backrest, sauna rocks, and an internal light fixture. As a result, we rate the features and extras at 4 out of 5. This also gives you the advantage of choosing between a wet vs. dry sauna experience.
The temperature can be controlled within the sauna with two knobs, making it incredibly convenient.
GGR Everything lead reviewer Lindsay Scheele, CPT, CNC
Alternatives
Fair warning: Assembling the Redwood Outdoors Thermowood Cabin is not for the faint of heart, earning it a mediocre 3-out-of-5 rating for the category. While the pieces are designed for easy interlocking and the model requires minimal screws, the instructions were for an older model and proved unhelpful. This forced our team to troubleshoot amongst the 300 or so pieces to properly build the sauna.
“The biggest issue we ran into was the screws that came with the sauna,” Lindsay says. “They were a very cheap, imported metal that would shred apart when met with any resistance, such as going into the wood.”
As with most outdoor saunas, this Redwood Outdoors sauna requires 240 volts, which is less common voltage and may require you to have an electrician install an appropriate outlet for it. Lastly, you want a level floor, or else this sauna’s pieces may not fit together properly.
If the setup process seems overwhelming for the Thermowood Cabin Outdoor Sauna, the Sun Home Luminar Outdoor Infrared Sauna may be a worthwhile alternative having earned a 4-out-of-5 rating for delivery and setup.
Testing Breakdown
Take a closer look at how the Redwood Outdoors Thermowood Cabin Outdoor Sauna scored across all categories.

Best Budget Outdoor Sauna: SaunaBox SmartSteam Kit Pro
Updated by: Stephen Sheehan, CPT, CNC
The SaunaBox SmartSteam Kit Pro offers an easy and affordable wet sauna option for home recovery sessions. It’s compact, folds down effortlessly, and is suitable for one person at a time. The heat is sourced from the SmartSteam Unit, which pumps steam into the SaunaBox and can be set to seven different settings.
What our tester says:
“It should take you less than 10 minutes and about 10 minutes to disassemble and clean it thoroughly.”
At a Glance
- Budget indoor/outdoor sauna
- Below-average temperature range
- Requires a 110V outlet, which is standard in most homes
- Below-average warranty
While you can go with a super cheap option like a sauna blanket or personal sauna tent, you won’t be able to go outdoors with those profiles. For our budget pick, we went with an affordable sauna that can give you a nice sauna experience outdoors (as long as you have access to a 110-volt outlet). Priced at $449, the SaunaBox SmartSteam Kit Pro combines a compact design with efficient performance, helping it earn a perfect value rating of 5 out of 5.
Heat Performance: 4/5
Value: 5/5
Footprint: 4/5
Why We Like The SaunaBox SmartSteam Kit Pro
As one of the best portable saunas we’ve tested, the SaunaBox uses a SmartSteam chamber to generate heat and can reach up to 140 degrees. While the max temperature is lower than other saunas, the humidity inside the SaunaBox will make it feel much hotter than it actually is. The brand’s website says it can reach its max temperature in 15 minutes, but certified personal trainer Anthony O’Reilly found it took a bit longer.
That said, once it got hot, it stayed hot, helping it earn a 4-out-of-5 score for heat performance. According to another product tester, “The cover did an excellent job of containing the heat. The sauna stayed hot for my entire 10-minute session.”
The SaunaBox can only fit one person, but even taller users should be able to sit in it comfortably. Anthony is 6 feet, 3 inches, for example, and felt there was enough space for his tall frame. It’s also compact, so you can fit it in a small garage gym.
Despite being budget-friendly, it’s not cheaply made, either. Constructed with BPA-free antimicrobial materials to help prevent mold and bacteria buildup, we rated the SmartSteam Kit Pro a 4 out of 5 for durability and construction.
The setup on this is incredibly easy. It should take you less than 10 minutes, and then about another 10 minutes to disassemble and clean it thoroughly.
GGR Everything lead reviewer Lindsay Scheele, CPT, CNC
Alternatives
Unlike other saunas on this list, you’ll need to dedicate some time to clean the SmartSteam Kit Pro after every use. We recommend using a mild cleaner, airing out the foot pad (which is machine washable), and airing out the entire sauna to allow all the humidity to escape. We docked a point off the footprint and portability score (4 out of 5) since you want to be careful with how you store it.
“You don’t want this to become a breeding ground for mold and germs by packing it away wet,” GGR Everything lead reviewer Lindsay Scheele says.
Another callout worth mentioning: This portable sauna only heats up to 140 degrees Fahrenheit. This is on the low end for saunas, so if you’re looking to really crank up the temperature, we recommend looking elsewhere.
If you want something similar and don’t mind using a wood-burning stove, the Sweat Tent is a budget-friendly and portable option.
Testing Breakdown
The SaunaBox SmartSteam Kit Pro scored well across the board despite its budget-friendly price tag. Here’s a breakdown of how it fared based on our testing methodology.
Vs. The Average
The SaunaBox SmartSteam Kit Pro may have a short warranty, but it’s less than half the price of the average portable sauna. One of the reasons it earned a perfect value rating is that its temperature range and dimensions are on-par with higher-priced competitors.
| SaunaBox SmartSteam Kit Pro | Average Portable Sauna | |
| Price | $449 | $1,107 |
| Dimensions | 35” L x 35” W x 74” H | 36.4″ L x 33.25″ W x 70.9″ H |
| Temperature range | Up to 140º F | Up to 140º F |
| Capacity | 1 person | 1 person |
| Product Weight | Not disclosed | 31.12 lbs |
| Warranty | 1 year | 3 years |
Although we’ve yet to do a full review on the SmartSteam Kit Pro, you can learn more about its even more portable cousin in our SaunaBox Go review, which is now called the SaunaBox Smart Steam XL.
Best 2-Person Outdoor Sauna: Redwood Outdoors Duo Sauna
Updated by: Stephen Sheehan, CPT, CNC
The Thermowood Mini-Cube Sauna from Redwood Outdoors is a compact two-person outdoor sauna, made for tight spaces or urban backyards. The Thermowood used is heat-treated Scandinavian softwood made to be resistant to cracking, warping, mildew, and insects.
At a Glance
- Mid-range outdoor dry/steam sauna
- Above-average temperature range
- Requires a 220V outlet—may require professional installation
- Lower-than-average warranty
Featuring a traditional design with a modern aesthetic, the Redwood Outdoors Duo Sauna is our pick for the best two-person outdoor sauna. Formerly known as the Mini-Cube Sauna, this model is ideal for couples or people living in the city who need a compact solution for an urban backyard. With a footprint just over 5 feet by 4 feet, we think the Duo Sauna meets the mark here, providing enough room for two users without taking up too much space. Our team scored the construction and durability at 4.5 out of 5—a testament to Redwood Outdoors’ build quality.
Heat Performance: 5/5
Construction: 4.5/5
Value: 4/5
Why We Like the Redwood Outdoors Duo Sauna
Although we haven’t sat inside the Duo Sauna yet, we’ve tested its roomier sibling, the Redwood Outdoors Thermowood Cabin Sauna—our pick for the best outdoor steam sauna. GGR Everything lead reviewer Lindsay Scheele, CPT, CNC, rated the four-person model’s heat performance at a perfect 5 out of 5. “Once we got everything set up, it worked perfectly,” she told me.
The Duo Sauna has a nice design with rounded corners that are reminiscent of some barrel saunas. With heat-treated thermowood, it’s resistant to mildew and bugs. It’s able to retain its shape better, too, since the thermowood is dried of any moisture or resin that could cause cracking, swelling, or warping down the road. You have the option to add shingles to the roof for more protection, as well. We rate the features and extras at 4.5 out of 5, especially since Redwood Outdoors offers add-ons like a bucket and ladle, wooden sauna step, and hanging aromatherapy diffuser.
We got the temperature up to 190 degrees Fahrenheit in just over half an hour. More importantly, it held its temperature and humidity with no issues.
GGR Everything lead reviewer Lindsay Scheele, CPT, CNC, on the similarly-built Thermowood Cabin Sauna
Alternatives
Based on our experience with the Cabin Outdoor Sauna, our main callout about the Duo Sauna is the setup process. Though it doesn’t look quite as complicated since its front and back walls come preassembled, the assembly requirements for this sauna are sizable. As a result, we rate the delivery and setup at 3 out of 5.
Another area where the Duo Sauna falls short is with its warranty. Redwood Outdoors only provides one year of coverage. Considering this two-person sauna costs nearly $6,000, we’d like to see at least two or three years, if not longer. We only scored it a 2.5 out of 5 for warranties and policies.
Need space for more than two people? Check out the Almost Heaven Morgan Barrel Sauna, which allows four users to sit comfortably.
Testing Breakdown
The Redwood Outdoors Duo Sauna scored well in several key categories, including durability and construction and heat performance. However, it also fell short of expectations in a few areas, too.
Vs. The Average
The Redwood Outdoors Duo Sauna offers a higher temperature capacity and roomier design than its competitors. However, it’s important to note the stark difference in warranty coverage.

Best Outdoor Barrel Sauna: Almost Heaven Morgan Barrel Sauna
Updated by: Stephen Sheehan, CPT, CNC
The Almost Heaven Morgan 4-Person Barrel Sauna is a barrel-shaped sauna to help circulate heat throughout the sauna evenly. This helps keep the temperature more uniform no matter how close or far you are from the Harvia heater. A more affordable option, this barrel sauna is suitable for both outdoor and indoor use, as well as steam or dry heat.
What our tester says:
“It works great; I’ll usually turn it on about half an hour before my athletes are ready to use it, and it’ll be around 190 degrees by the time they hop in.”
At a Glance
- Upper mid-range indoor/outdoor dry sauna
- Above-average temperature range
- Requires a 110V outlet
- Above-average warranty
When we talk about traditional saunas, we’re not necessarily talking about the shape of the sauna, but, rather, the method of heating. Traditional saunas are dry saunas that use electric or wood-burning heaters to produce heat, usually with sauna stones included, too. The Almost Heaven Morgan Barrel Sauna provides a traditional sauna experience while using a barrel shape to distribute heat evenly throughout. It’s one of our favorite models we’ve tested, earning an impressive overall score of 4.2 out of 5 and our best outdoor barrel sauna nomination.
Heat Performance: 5/5
Value: 4/5
Features & Extras: 3/5
Why We Like The Almost Heaven Morgan Barrel Sauna
Capable of being used indoors or outdoors, the Almost Heaven Morgan Barrel Sauna comes with a limited lifetime warranty on the sauna structure and five years on the heater. Given its $8,165 price tag, that level of protection enhances the value further, leading us to give a 4-out-of-5 rating in this key category.
Sean Rigsby, USA Weightlifting Junior National Team Coach, has this barrel-style sauna in his gym and is impressed with how quickly it can get warm, giving the sauna a 5 out of 5 for performance. The Morgan barrel sauna can fit four people pretty comfortably, although a six-person sauna is available for larger parties.
We also appreciate that the Harvia heaters include 40 pounds of sauna stones, which will allow you to ladle water over the stones to create a steamy, humid environment.

Alternatives
One of our only callouts about the Almost Heaven sauna main is the delivery and assembly process. Unfortunately, the instruction manual isn’t specific to this model. Instead, it’s a generic set of instructions for assembling barrel-style saunas from Almost Heaven, resulting in a 3-out-of-5 rating.
“It certainly complicated things for an already lengthy build,” Sean says. Furthermore, the barrel shape may be aesthetically appealing to some and not to others.
For those who want a premium, spa-like look, we recommend the Plunge Sauna.
Testing Breakdown
Here’s how the Almost Heaven Morgan Barrel Sauna scored after we evaluated it against our testing methodology.
Vs. The Average
This 4-person barrel sauna is larger and slightly heavier than the average home sauna. It can also reach a higher temperature while offering a larger seating capacity.
| Almost Heaven Morgan Barrel Sauna | Average Home Sauna | |
| Price | $8,165 | $8,295 |

Other Saunas We Researched
From portable, single-person designs to robust models that can seat four or five people, there are plenty of options to consider. Here are a few saunas we researched and tested that didn’t quite make the cut for this best outdoor sauna list.
- Relaxe Caldera Infrared Sauna: Packed full of features, this infrared sauna earned one of the highest overall scores of any sauna we’ve tested. Unfortunately, it’s not designed for outdoor use.
- Sweat Tent Outdoor Sauna: While we like its portable design, the fact it requires a wood-fired stove as its heat source makes it far less convenient than the SmartSteam Kit Pro.
- Durasage Oversized Portable Personal Steam Sauna: This outdoor sauna kit is fairly roomy. However, it only allows for sitting, which may not be comfortable for all users.
How We Picked and Tested The Best Outdoor Saunas
We’ve tested 30 saunas (with more to come) since prioritizing finding the best muscle recovery tools. For each of these saunas, we performed multiple tests, measuring the top temperatures for each, as well as the time it takes for the sauna to warm up.
Here’s a more detailed explanation of how we pick and test outdoor saunas:
- Delivery and setup: We looked for how easily we could construct the sauna and noted any snags we hit along the way. Saunas scoring 3 out of 5 or higher have clear instructions, hassle-free delivery, and can be put together with little hassle.
- Construction: Because different wood types have different properties, we take a careful look at how each outdoor sauna is constructed. For outdoor saunas, the wood used should be resistant to insects and mildew. In addition, a well-designed unit should not have any leaks or gaps where heat can escape. Saunas that meet these standards score at least a 3 out of 5 in this category.
- Footprint: Even compact saunas can be big, so we looked for the sauna to be used efficiently, providing good capacity for the amount of space the sauna takes up. To earn a 3 out of 5 or higher, the sauna must have enough space to seat the recommended number of people comfortably.
- Performance: What is the sauna’s maximum temperature, and how quickly does it get there? We also noted the type of sauna heater used, as some are more efficient than others. Saunas that heat up within a reasonable amount of time earn at least a 3 out of 5.
- Features and extras: This is any sort of convenience feature or add-on to the sauna, ranging from a thermometer to chromotherapy LED lighting to Wi-Fi. Some manufacturers offer sauna accessories like a bucket and ladle, step, or cleaning and maintenance kit. To earn a 3 out of 5, saunas need to at least have the ability to read and adjust temperatures well.
- Value: The price has to make sense for the build, capacity, and performance of the sauna. This score compares how the sauna stacks up to other saunas in a similar price range, and determines if you’re actually getting your money’s worth.

Benefits of Outdoor Saunas
Indoor saunas may share quite a few benefits to outdoor saunas, but even so, outdoor saunas can provide some unique advantages. Here are a few ways you can support your overall health and well-being with an outdoor sauna.
The Space
Sometimes, you just don’t have the space in your home for an indoor sauna. Everyone has a different living situation, but most homeowners can usually find adequate space for a large backyard sauna before they can find the space inside their own home. Keeping your sauna outdoors can allow you to utilize your interior space more effectively (perhaps even filling it with some of the best home gym essentials).
The Scenery
I get it; you could have a really nice-looking garage or room in your house. Still, there’s something a bit more relaxing about being able to sit in a sauna and see trees, bushes, and other greenery through its windows and doors. There’s no health or wellness benefit to being outdoors while sauna-bathing, but I imagine the scenery will be a stress reliever to most people.
The Recovery
Although not unique to outdoor saunas, the heat therapy of saunas has been shown to do wonders for a user’s recovery. A small study from 20231 suggested that athletes who sauna-bathed showed less muscle soreness and greater perceived muscle recovery. Another study from 20182 showed regular sauna use could increase the amount of anti-inflammatory proteins in the body.
“Saunas not only provide benefits like better blood flow and decreased stress but also can help you detox through increased sweating, making it easier to breathe and boosting your physical endurance,” says Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM. “They also offer potential support for muscle recovery and growth as well as positive effects for your cognitive function.”
Saunas can also stress the cardiovascular system, increasing blood flow and heart rate. However, a 2019 study4 measured resting heart rates after a workout and then after a sauna session post-workout. Resting heart rates were lower after the sauna session than they were post-workout.
The Heat
The majority of outdoor saunas will be traditional dry saunas, as some infrared heaters (but not all) can be more fragile and may not survive harsher weather extremes. This means most outdoor saunas can get hot—close to or even over 200 degrees Fahrenheit.
Sauna expert and assistant strength and conditioning coach for the Carolina Panthers Thomas Barbeau, CSCS, SCCC, says that a warmer heat will get you the most benefits from a sauna. “A lot of the research shows that the best temperature to reap the most benefits from a sauna is above 176 degrees for a 20-minute session,” he explains. “Temperatures at or above 200 degrees would require only a 15-minute session.”
The hotter temperatures of traditional saunas may help improve brain health. One 2017 study5 showed that heat stress and exercise can increase levels of brain-derived neurotrophic factor (BDNF)—a protein in the nervous system shown to help with memory function as well as anxiety and depression.
That said, it’s critical to stay on top of your hydration if you plan to use a sauna regularly.
“Sipping water in the sauna can help you stay a bit more comfortable, but it’s not enough to replace the fluids you’re losing,” says Dr. Raj Dasgupta. “It’s better to focus on drinking plenty before, after, and during your session to fully rehydrate. Think of sipping water during the sauna as a way to take the edge off, not as your main hydration plan.”
Types of Outdoor Saunas
Before you splurge on an outdoor sauna, it’s important to understand the different types available.
- Dry sauna: These saunas typically feature wood-lined interiors and have a heater—like an electric stove—on the inside. The temperature inside a dry sauna typically varies from 160 to 200 degrees Fahrenheit with 10% to 20% humidity.
- Wet sauna: This type of sauna utilizes steam to heat the interior. The temperature here is lower than in a dry sauna—100 to 120 degrees—and the humidity can reach as high as 100%.
- Infrared sauna: These saunas use electromagnetic radiation to warm your body rather than the room itself. They typically reach between 150 and 160 degrees, but they’re not as common in outdoor models.
Buying Guide: What to Look for in the Best Outdoor Saunas
Want an outdoor sauna that’ll last through the hottest summers and coldest winters? Here are the things to consider when shopping for an outdoor sauna.
Materials
One of the most important things to check for an outdoor sauna is the type of wood being used. In addition to being sturdy, the wood needs to be able to withstand the harsher elements of the outdoors. A common wood for outdoor saunas is red cedar, which has been shown to be more resistant to mildew and insects.
Sauna Type
Most outdoor saunas are traditional dry saunas with the option to become steam saunas (if you add enough moisture to the sauna stones and room). These dry saunas can approach 200 degrees, although warming up to that temperature may take time.
Infrared saunas are far less common for the outdoors, mostly because the components of infrared heaters can be fragile. Infrared saunas can heat up in minutes, although the maximum temperature isn’t as high—usually between 150 and 160 degrees. If an infrared sauna is suited for the outdoors, keep in mind that it’s probably more expensive, too, to provide adequate protection for the infrared heaters.
Electrical Compatibility
Most outdoor saunas will use a 30-amp heater, meaning it’ll require 220 or 240 volts—a far less common voltage than the American standard of 110 or 120 volts. If this is your first outdoor sauna, there’s a good chance you’ll have to call an electrician to install the new outdoor-ready outlet, which will add to the overall cost of the sauna—it cost us about $1,600 at GGR to get one installed at our warehouse.
If you don’t have an outlet suited for an outdoor sauna, make sure to factor this electrical installation into your budget.
Features and Amenities
Any extras to a sauna are a plus, but they can vary in outdoor saunas. Most electric saunas have some sort of lighting for evening sauna sessions. Others have the added convenience of being operable from your smart device. Still, others keep it to basics, with a basic thermometer or bucket and ladle to operate the heat of the sauna. Research which add-ons are right for your needs so you can create the ultimate home sauna experience.
Cost
Even if you’re getting good value, saunas are expensive, especially if they’re built to withstand outdoor weather conditions. Make sure the sauna and installation costs fit your budget, and that the home sauna cost is worth the features and performance it brings.
Safety
There’s a lot to learn about sauna safety. First off, you should talk to your doctor before using a sauna. This is especially important for anyone with a pre-existing health condition, like high blood pressure or cardiovascular issues.
You should also only purchase an outdoor sauna that has clear safety guidelines. Follow the instructions closely and listen to any and all guidance on how long you should stay in the sauna and how hot it should be inside. In general, beginners should only stay in a sauna for five to 10 minutes at a time. More experienced folks can go for 15 to 20 minutes. Just remember to always drink plenty of water and leave the sauna if you ever feel unwell.
Finally, follow all installation instructions carefully and use the correct power outlet for your sauna. Some saunas require a 240V outlet to operate. Since these aren’t as common in outdoor spaces, you may need to call an electrician to install one.
Ventilation
Ventilation is an important part of regular sauna maintenance. Adequate ventilation can help reduce the risk of mold and other water-related damage as you continue to use your outdoor sauna. These vents are especially important for wood-burning saunas as they help reduce the risk of smoke inhalation during sweat sessions.
As always, no matter what sauna model you have, be sure to leave the door open between uses to help the interior dry out and wipe away any pooled moisture in between sessions to help reduce mold and bacteria buildup.
Sauna Maintenance and Care
In order for your sauna to last, you need to learn how to take care of it. You can read our sauna maintenance guide for more details, and check out our most important tips below:
- Weather protection: Many outdoor saunas are built to withstand different weather conditions. That said, waterproof sealants and roof shingles don’t last forever. You’ll want to regularly inspect the roof of your sauna for leaks and reapply the sealant every year to prevent water from seeping inside.
- Winterization: Make sure the waterproof sealant on your outdoor sauna is in good condition before winter, and always clear snow from the top and away from the sides of your sauna after a storm.
- Regular inspections: In addition to the roof, you’ll want to give the inside and outside of your sauna a thorough inspection once every few months. Check for cracks, holes, water damage, mold, door integrity, and other potential issues.
- Moisture control: Chances are, your outdoor sauna has some form of ventilation to reduce water damage, but that’s not foolproof. Remember to leave the door open between uses and dry the seats off with a towel. This can help dry the inside of your sauna and prevent mold and bacterial growth.
- Electrical maintenance: Make sure all power cords are kept dry and away from the elements in order to prevent damage. Also, be mindful that many of the outdoor saunas on this list require a 240V outlet to operate. This might require an electrician to install a dedicated power source for regular use.
Cost of Owning an Outdoor Sauna
Outside of the initial cost of buying an outdoor sauna, you’ll need to keep additional costs in mind before making a purchase. These can include:
- Shipping and delivery fees: Though some brands offer free shipping on their saunas, sometimes you’ll have to pay a few hundred dollars for delivery. This varies by the brand and your location, but it’s something to be aware of.
- Installation costs: You may be able to install the sauna yourself, but some brands offer to do it for a fee. Plunge, for example, charges $1,800 for professional installation.
- Electrician costs: We already mentioned that you may need a professional electrician to install the proper outlet for your sauna. This cost varies by company—at GGR, we spent $1,600 on an outlet installation to test some outdoor saunas.
- Additional maintenance costs: Before attempting any repairs to your sauna, consult the brand to see if the issue is covered under the warranty. In that case, the brand may send a technician to your location to fix the issue. If you aren’t covered, you may have to pay out of pocket to a local repair service or attempt to fix the issue yourself.

Best Outdoor Sauna: FAQs
Is it worth getting an outdoor sauna?
An outdoor sauna can be a great way to add to your recovery and relaxation and experience plenty of potential health benefits. While an outdoor sauna can save space on the interior of your home, there may be added installation costs, such as installing a 240-volt outlet or building a level foundation for the sauna.
What is the best type of sauna to buy?
Saunas can vary drastically from budget-friendly sauna tents and blankets to grandiose eight-person sauna cabins. The best sauna to buy should fit your budget and needs with good value. Some of our top picks for the best home saunas include the Sun Home Luminar Infrared Sauna, Redwood Outdoors Cabin Sauna, and Sunlighten Infrared Sauna.
What’s better, an infrared or steam sauna?
While infrared saunas and steam saunas provide similar benefits like muscle recovery and reduced inflammation, infrared saunas can get much hotter much quicker than steam saunas. An infrared sauna can go up to 160 degrees compared to a steam sauna’s typical top temperature of 120 degrees (due to the humidity, although the perceived temperature will still be plenty hot). Additionally, infrared saunas need less maintenance than steam rooms due to the 100% humidity and moisture of the sauna.
Still, the added humidity of steam saunas can help relieve skin conditions like psoriasis or eczema. It can also provide sinus and allergy relief due to the moisture in the air. Both have pros and cons, and which type is best for you will depend on your needs and goals.
