As a strength athlete for the past 25 years, I love the relaxation felt after stepping out of one of the best cold plunge tubs. Sure, it can sometimes be less than pleasant during the ice bath, approaching near freezing temperatures. However, I enjoy the relaxation felt afterward—as well as the real-world ice bath benefits of muscle recovery and reduced inflammation1.

The big drawback to cold plunge tubs is the price, with many costing close to five-digit numbers. Inflatable ice tubs try to fix this by providing a lightweight, portable solution, but quite a few that we’ve tested lose their shape over time.

Hydragun has attempted to remedy this problem on both fronts, with a heavy-duty inflatable tub with your option of chiller, to help save you hard-earned money if you don’t need the most powerful water chiller on the market. In this Hydragun Supertub Cold Plunge review, we’ll take a look at this cold tub and see if it’s actually as good of value and quality as it seems from a bird’s eye view.

Let’s Break the Ice…We Know Our Cold Plunge Tubs

Garage Gym Reviews has been testing fitness equipment with a professional hand since its beginning in 2014. We’ve recently taken the dive into recovery tools such as cold plunges and home saunas, but we’re no strangers to professionally and honestly trying out equipment. Our team of certified personal trainers, lifting coaches, and competitive athletes bring the same expertise in trying and testing out recovery tools according to our fitness equipment testing methodology.

Certified personal trainer and lead reviewer of Garage Gym Reviews Everything Lindsay Scheele tested out the Hydragun Supertub Cold Plunge over several plunge sessions. During her time with the cold plunge tub, she rated several aspects of the ice bath, giving the following features a score between 1 and 5:

  • Delivery and setup
  • Footprint and portability
  • Construction and durability
  • Ergonomics
  • Conveniences
  • Draining and cleaning
  • Overall value

Hydragun Supertub

Hydragun Supertub Cold Plunge

GGR Score: 4.19 starstarstarstarstar

Product Highlights

  • 60-gallon cold plunge tub
  • Choice of 0.6- or 0.8-horsepower chiller
  • 52” L x 28” W x 24” H
  • Temperature range of 37-108 degrees Fahrenheit

Pros & Cons


  • Portable
  • Less expensive than other cold plunge tubs
  • Choice of chiller
  • Can be used as cold or hot tub
  • Durable military-grade vinyl


  • Chiller is noisy
  • $400 flat-rate shipping
  • Might be too small for taller or larger people

Bottom Line

The Hydragun Supertub Cold Plunge comes in two different size chillers—0.6 or 0.8 horsepower. If you’re in a more moderate climate, you won’t need the larger chiller. This inflatable cold tub is constructed of military-grade vinyl material and holds its shape well.

A Quick Look at the Hydragun Supertub Cold Plunge

Based in Singapore, Hydragun began as a business to make the best massage gun possible—not too loud, not too weak or strong. Since then, Hydragun has expanded their workout recovery line to knee massagers, cold plunge tubs, and their highly popular Heatpod sauna blanket.

The Hydragun Supertub is an inflatable cold tub, weighing only 21 pounds before filling it with water. This makes for a lightweight (and more affordable) cold plunge option. You have your choice between a 0.6-horsepower chiller or 0.8-horsepower chiller. While not as easily portable, the chiller has wheels and is compact, meaning it can still move around quite a bit.

The energy-efficient Permafrost chillers have an automated power-saving mode that can be activated overnight to allow you to save money while the tub isn’t in use.

The Hydragun Supertub is bought as a combination of the tub and whichever chiller you choose. If you’re looking for just a portable inflatable tub, you may want to consider the Tru Grit Cold Tub, which is sold separately from its chiller.

Before You Buy

  • Hydragun recommends the larger chiller only if the climate in your area has more extremes—hotter summers or colder winters—and would require a little more gumption to reach the desired temperatures.
  • The chillers can be set at temperatures from 37 to 108 degrees Fahrenheit, meaning the Supertub is an all-in-one ice bath and hot tub.
  • Shipping is a flat fee of $400 in the contiguous United States, regardless of which size chiller you purchase. This actually lowers the value of the larger chiller, as that becomes a bit overpriced compared to other comparable inflatable cold tubs.

Hydragun Supertub Cold Plunge Video Review

Is the Hydragun Supertub Cold Plunge Worth It?

The smaller chiller sits at just under $3,000 on Hydragun’s website, while the larger chiller makes the price about $4,000. However, in her full video review of the Supertub, Lindsay makes mention that shipping is a flat rate of $400—regardless of the chiller you choose—meaning that the prices are closer to $3,400 and $4,400, respectively.

At this price point Lindsay suggests that the smaller chiller has some value, as you won’t find a chiller and tub combo for less money. The larger chiller’s price becomes comparable to other inflatable cold plunges, though. 

The Inergize Cold and Hot Plunge Tub is priced at just under $100 more, and it is a larger tub, making it more ideal for a taller person. The Tru Grit Cold Tub is priced at $3,900 when bundled with their Ice Box chiller. Both of these other options have a 0.8-horsepower chiller as well.

With that said, the tub is made of high-quality nylon material which keeps its form much better than most inflatable ice baths we’ve tried out. If you’re looking for a heavy-duty tub that can easily be moved around, it might be worth the price tag. Lindsay rates the value of the Supertub a 4 out of 5.

Great for:

  • People needing a portable cold tub
  • Those wanting a durable inflatable ice bath
  • People who want hot and cold tub abilities

Not recommended for:

  • Larger or taller users, typically over 6 feet tall
  • Those searching for the best value in their purchases
  • Users who want to save money with a DIY cold plunge

Using the Hydragun Supertub Cold Plunge 

GGR Lead Reviewer Lindsay Scheele, ISSA-CPT, tried out the Hydragun Supertub Cold Plunge over a few sessions. The chiller is able to go as low as 37 degrees Fahrenheit, or as hot as 108 degrees. Lindsay says the hot function is a bit higher than most chillers. “Normally, we’ve seen top temperatures of 102 or 104 degrees,” she says.

While in use, the chiller is one of the noisiest chillers we’ve tried. Lindsay adds, “It’s noticeably louder than others we’ve tried out. It won’t be much of an issue outside, but if you use it indoors, just know it’ll be loud enough to echo in a small room a bit.”

Lindsay tests the Hydragun Supertub Cold Plunge with a decibal meter.

Another thing she noticed while testing is that the tubing on the cold tub formed much more condensation than other cold tubs. Like, a lot. There was water dripping from the tubing. Again, this probably won’t be a big deal if you’re using it outdoors, but inside, it might cause some water damage to your floors if you’re not careful.

The cold plunge performed well and the chiller was effective, but because of the callouts above, we’d recommend this a little more for outdoor use than inside.

Footprint and Portability

At 52 inches long and 28 inches wide, the Hydragun Supertub is a compact cold tub. It only weighs 21 pounds dry, making it very easy to move around from one spot to another. While the chiller is 68 or 82 pounds, depending on the size, it’s set on wheels and pretty easy to maneuver as well. If you’re not satisfied with where you have it, the amount of work to relocate is minimal, earning the Supertub a 5 out of 5 for its footprint and portability.

Durability and Construction

Compared to other inflatable ice baths, the Hydragun Supertub shines in its construction and durability, earning it a 4.5 out of 5 in this category. The Supertub is constructed of an SGS-certified military-grade marine vinyl. The military-grade material means it’s meant to last, and so far, it’s held up in Lindsay’s cold plunge experience.

Linsday smiles while lifting herself out of the Hydragun Supertub Cold Plunge.

Lindsay explains, “A lot of inflatable tubs start to lose their shape after a few uses; I can’t sit or lean on them too much or else the tub will start to bow or cave in. The Supertub holds up way better than others I’ve tried, and we’ve moved it, drained it, and filled it multiple times. I’ve sat on the edge with my full weight and it’s held its shape, too.”

The Ergonomics

With a 60-gallon capacity, the Supertub fit Lindsay just fine. However, at 5 feet and 4 inches tall, Lindsay admits that the smaller capacity of the cold tub may not suit larger or taller people. We had other product testers who are 6 feet tall try out the tub for cold water immersion, and they feel cramped in the cold plunge. Lindsay rates the ergonomics a 2 out of 5, as the smaller size won’t be suitable for everyone.

While the extras and features are fairly basic, the Supertub comes with quite a few nice perks. For one, a tub cover is included, which we feel is always a misstep if a cold plunge doesn’t include it (like with a couple Polar Monkeys Cold Plunges). It also has an anti-slip mat included to place your tub on, especially if you’re using your cold plunge outside.

For its filtration system, the Supertub includes a few items to help ensure the water is clean and pure through multiple sessions. A mesh strainer is provided for larger debris, and a water-balancing kit is included to ensure the water is at the right levels. Lindsay rates the conveniences a 4 out of 5.

One of the most unique inclusions in this Supertub kit is a phone mount, or selfie stick. You’ll be able to mount the phone to the side of your tub and watch your favorite YouTube or Netflix shows, or you can post a video of you surviving your cold plunge session. “I want to share with everyone if I did a session in under 40-degree water, so I love the inclusion of this selfie stick,” Lindsay jokes.

Lindsay smiles into a camera while standing in front of the Hydragun Supertub Cold Plunge.

Draining and Cleaning

Along with the added water-balancing kits, the chiller includes a commercial-grade ozone generator. The self-cleaning generator creates ozone by adding energy to oxygen molecules within the water, which is then used for water disinfection and air purification. “Basically, it means it helps keep the water really clean through multiple uses,” Lindsay says. “My water has stayed clean after a few uses, so so far, so good.”

When it is time to drain the tub, there’s a drain plug that’s easily accessible. However, because we found the tubing to cause a lot of condensation, there may be a bit more upkeep involved with this cold tub—especially if you keep it indoors. Because of that, Lindsay rates the draining and cleaning a 4 out of 5.

Hydragun Supertub Cold Plunge vs Inergize Cold and Hot Tub

Inergize Cold and Hot Tub

Inergize Cold And Hot Plunge Tub

GGR Score: 4.35 starstarstarstarstar

Product Highlights

  • Inflatable cold plunge tub
  • Filtration system and chiller
  • App for temperature control
  • Set temperature from 37 to 105 degrees

Pros & Cons


  • App control for temperature
  • Portable and packable
  • Replace water every 3-6 months


  • Expensive
  • Tub inflates with hand pump
  • Over a 4-week lead time for shipment

Bottom Line

The Inergize Cold and Hot Plunge Tub allows you to regulate the water temperature with the touch of your phone. You can prepare the water for hot or cold therapy modalities depending on your needs. The inflatable tank is portable and comes with a duffle bag for packing up and bringing with you. The tank has a 60- to 70-gallon water capacity and you can choose your temperature between 37 to 105 degrees.

The Hydragun Supertub is very comparable to the Inergize Cold and Hot Tub, with a couple of impactful differences. The prices are similar with the 0.8-horsepower models, because of the $400 flat shipping cost for the Supertub. The 0.6-horsepower chiller on the Supertub is  significantly cheaper, and is more cost-effective, if you don’t need a stronger chiller where you live.

Both tubs have similar dimensions and weights. However, the Inergize tub has a higher height, able to keep taller users (up to 6 feet and 4 inches) submerged to the neck. You won’t be able to do that with the Hydragun Supertub. So for larger people, Inergize is the way to go.

Customer Experience 

The Supertub has respectable policies for cold tubs. For one, there is a 30-day return policy, a risk-free guarantee to return the tub and get a refund. Lindsay warns, however, that “returning big items like a cold plunge tub or an exercise bike can be a pain in the butt.” So, make sure you really want the tub to avoid any hassle.

Additionally, the Supertub also has a 2-year warranty, which any time a cold tub offers multiple years on their warranties, it’s a win in our books. The Hydragun Supertub Cold Plunge gets a 5 out of 5 for its strong policies.

Speaking of customer service, Hydragun has a couple of ways to contact them for any issues or questions, notably email or a contact form. With a pretty substantial FAQ page, Hydragun gets a 4 out of 5 for customer service.

Ordering and Assembling the Hydragun Supertub Cold Plunge

Although Hydragun sells a few of its products on Amazon, the Supertub can only be purchased from hydragun.com. Financing is available through PayPal with interest-free payments every 2 weeks, or equal monthly payments. (The options and terms will depend on the price and your credit.) The Supertub is also HSA- and FSA-eligible.

There is no lead time for the Supertub; you should get your tub within 3 to 6 business days in the contiguous United States. (Alaska and Hawaii have to wait a bit longer, with delivery times of 7 to 9 business days.)

Assembly is virtually non-existent, as the cold tub comes with an electric air pump. It takes a few minutes to charge the pump, and about 10 minutes to fill the tank with air. We’d give the delivery and setup a perfect score, but because of the $400 flat rate shipping cost, we give it a score of 4.5 out of 5.

Customer Reviews

There are currently 17 product reviews of the Hydragun Supertub on the product’s website at the time of this writing. Those reviews are overwhelmingly positive, averaging 4.9 out of 5 stars, with only one 4-star review and the rest 5 stars.

Many of the positive reviews like the portability of the tub, along with an easy setup and assembly. They like the construction of the tub and think it’s an affordable price.

The lone 4-star review also thoroughly enjoys using the tub, but they wouldn’t give full marks, because they didn’t want to set it up themselves. While a white glove installation would be nice, the amount of setup required for this is pretty minimal, as the reviewer even admits to it taking less than 30 minutes.

Final Verdict of Our Hydragun Supertub Cold Plunge Review

The Hydragun Supertub is a high-quality inflatable ice bath made with heavy-duty materials. Compared to similar products, the 0.8-horsepower Supertub is comparable in price to other inflatable tubs with larger capacities, making it a less-than-ideal choice, especially for taller athletes.

However, the smaller 0.6-horsepower chiller comes in at a lower price, making it a more cost-effective option for smaller people who don’t mind the size of the tub and who won’t need a more powerful chiller for extreme weather conditions. 

While this is a well-built tub, your specific needs will definitely impact the amount of value you see in this cold tub.

Hydragun Supertub Cold Plunge: FAQs

Where does the Supertub ship from?

Hydragun ships their products from their warehouses, located in Singapore and the United States.

How long should you stay in a cold plunge?

While the time will be affected by the temperature of the water and by your comfort with cold therapy, most users aim for 5 to 10 minutes during a cold plunge session. Beginners learning how to cold plunge should aim for only 1 or 2 minutes as they learn to acclimate to cold water immersion.

What temperature should a cold plunge be?

Most cold plunges aim for a cooler temperature of around 55 degrees Fahrenheit, although as you acclimate yourself to cold plunges, many users aim for cooler temperatures, some even going under 40 degrees Fahrenheit.
