If you’re on the hunt for the right cold plunge tub to aid workout recovery or practice Wim Hof breathing, Polar Monkeys is a brand that offers a variety of cold therapy plunge products. In this Polar Monkeys Cold Plunge review, I’ll give you insight from our hands-on experience with three of the most popular cold plunge tubs the brand has to offer. 

We’ve Tested a Dozen Cold Plunge Tubs

Garage Gym Reviews is staffed with fitness industry experts who know a thing or two about strength, conditioning, and recovery. Our experts also have certifications to back up our obsession with all things health and wellness. 

For this Polar Monkeys Cold Plunge review, GGR expert tester and ISSA certified personal trainer Lindsay Scheele took the dip in three different Polar Monkeys tubs to gauge the water capacity and chiller power, and to determine if each tub is worth the investment. Lindsay also used our GGR in-depth fitness equipment testing methodology to score a variety of categories on a 1-to-5-star scale. Here are some examples of categories she scored: 

  • Delivery and setup: What is the set-up process like? Does the tub require plumbing and electrical work?
  • Conveniences: Does this tub have Bluetooth temperature control (or any temp control)?
  • Draining and cleaning: How will folks at home drain and clean this tub?
  • Financing, warranty, and returns: What kind of financing or HSA/FSA options do customers have? Is contacting the company on warranty and return issues difficult?

Which Polar Monkeys Cold Plunge Should You Buy?

When shopping for a cold plunge with Polar Monkeys, you can expect your purchase to come with the tub, chiller (that can heat and cool), connection hoses, and built-in filtration system. But each tub has a few distinct features that are worth reading about before you buy.

I’ll lay out the main differences in a bit with a side-by-side comparison chart, but for now, I’m going to outline what you can expect from the three cold plunges tubs we tested from Polar Monkeys: 

  • Cooling and heating range from 39 to 102 degrees Fahrenheit
  • Standard 0.6 horsepower chiller (0.8 if you choose the Pro option)
  • Smartphone connectivity to set the temperature on the chiller
  • Traditional 120-volt electrical requirement
  • No plumbing required
  • 1-year warranty with option to purchase an extended warranty
  • Built-in 20-micron filtration system  
  • Chlorine free and ozone sanitation

Polar Monkeys Portal 2.0

Good for: Folks looking for a durable cold plunge for the outdoors

Portal 2.0

Polar Monkeys Portal 2.0

GGR Score: 3.75 starstarstarstarstar

Product Highlights

  • Galvanized steel cold plunge tub
  • Cooling and heating capabilities
  • Control temperature with an app
  • Tub comes in two sizes
  • Multi-color underwater light included

Pros & Cons


  • HSA/FSA eligible purchase
  • Cooling and heating power
  • Free shipping in USA
  • Filtration system


  • Tub cover sold separately
  • Potential for condensation without insulation
  • Short 1-year warranty
  • Recommend for outdoor use only

Bottom Line

The Polar Monkeys Portal 2.0 is an uninsulated galvanized steel tub ideal for outdoor use. It can heat or cool and there are two sizes available: Standard and Large. The width and height are the same on both tubs, the difference being the length: 48 or 60 inches. Because this tub is not insulated it can condensate.

The Polar Monkeys Portal 2.0 is a stylish galvanized steel tub designed for both cold and hot tub modalities. It also features the least expensive price tag for the cold plunge tubs on the brand’s website, with prices starting at $3,290.

Prices vary depending on the color option you choose (silver, white, black, or limited edition art), chiller size (0.6 or 0.8 hp), and tub size (either 40 or 60 inches long). If you go with the longer, 60-inch tub, keep in mind it’ll weigh a bit more and have a larger water capacity.  

It’s worth noting that this is the only tub on the Polar Monkeys website that is for outdoor use only. This steel tub is not insulated, which may lead to condensation (and water damage) if set up indoors. 

While it is an outdoor-only tub, our tester Lindsay reassures us that this is a heavy-duty and durable product. “The Portal 2.0 is built to withstand all outdoor conditions,” says Lindsay. 

“The exterior paint will damage or peel off before anything happens to the tub itself,” she adds. For this reason, the Portal 2.0 earns a 5-star rating for durability. 

Lindsay also appreciates the fact this tub required very little assembly and scored the tub a 4-out-of-5-star rating for set-up. “The only thing you have to do is connect the hoses to the tub and chiller. It does not require plumbing or added electrical,” says Lindsay. 

However, filling the 100-gallon tub took about 40 minutes. But Lindsay says the gallons per minute flow in the GGR testing facility is a little slow and will differ for folks at home. 

Cleaning and draining is another factor we test and score, knowing you’ll have some upkeep with your purchase. Lindsay admits that the Portal 2.0 was tested indoors (although not recommended) and she used a water pump to get most of the water out of the tub upon draining.

“Because this is supposed to be outdoors, two people could tip this over and dump out the remaining water,” she says. It’s still not as easy as she’d like it to be, so she gives it a 3.5-out-of-5-star rating. 

Polar Monkeys Brainpod 2.0

Good for: Anyone looking for a spa-like cold plunge experience at home 

Brainpod 2.0

Polar Monkeys Brainpod 2.0

GGR Score: 4.1 starstarstarstarstar

Product Highlights

  • Cold therapy tub and chiller 
  • Temperatures as low as 39 degrees Fahrenheit 
  • 0.6 horsepower chiller and filtration system

Pros & Cons


  • Provides filtered water
  • Three color options
  • Upgrade available to have hot and cold water


  • Heavy
  • Small footprint and water capacity
  • Expensive

Bottom Line

The Polar Monkeys Brainpod 2.0 is a fairly small cold plunge tub option. While the website doesn’t indicate how many gallons of water it takes to fill the tank, the website does provide the weight with and without water, so we estimate it has a 55-gallon capacity.

The Polar Monkeys Brainpod 2.0 is a cold plunge tub with both cold water and hot water capabilities. What makes this tub different from the other Polar Monkeys tubs is the fact it’s a fully insulated acrylic tub rated for indoor or outdoor use. 

The sleek tub comes in black, white, or two limited-edition art options. The tub is well-built and ergonomic with a slight angle on either end, allowing you to recline and take in a luxury experience in the comfort of your own home. And with a luxury experience, you can expect a luxury price point. The pricing on the Brainpod 2.0 starts at $4,590 and varies depending on colorway and chiller size. 

RELATED: The Cold Plunge Review

The Brainpod 2.0 earns 5-star ratings for setup and durability. Much like the Portal 2.0, set-up was a breeze and the Brainpod doesn’t require plumbing or special electrical outlets. 

GGR tester Lindsay also notes the tub is super stable and durable. “I didn’t experience wobbling or give when it was empty or filled with water,” says Lindsay. Not only is the tub durable, it’s also suited for indoor use because it’s fully insulated and won’t condensate. 

Other than the materials the tub is made from, the main difference Lindsay notes about the Brainpod is the draining system. “There is a drain at the bottom of the cold plunge, just like a traditional bathtub,” says Lindsay. This feature means you won’t have to mop, pump, or tip the tub to get the last bits of water out. There is also a way to attach a garden hose to the built-in drain for easy indoor draining. 

Star Treatment 2.0

Good for: Anyone who prefers a vertical-style cold plunge tub

Star Treatment

Star Treatment 2.0

GGR Score: 4 starstarstarstarstar

Product Highlights

  • Insulated acrylic cold plunge tub
  • Heating and cooling capabilities
  • Remote temp control with app
  • Chiller features filtration and sanitation

Pros & Cons


  • No plumbing required
  • Fully insulated
  • Indoor or outdoor use
  • Artistic designs and two colorways


  • Cover sold separately
  • Short warranty
  • Outdoor temperature may affect ability to heat and cool

Bottom Line

The Polar Monkeys Star Treatment 2.0 is a fully insulated acrylic cold plunge tub with both heating and cooling options. No plumbing installation is required to set up the tub and the 0.6 horsepower motor features built-in filtration and sanitation systems for easy maintenance.

The Polar Monkeys Star Treatment 2.0 is a rustic-style barrel-shaped cold plunge with a stainless steel interior and a wood exterior made from Canadian Red Cedar. It earns a 5-star rating for construction and durability and our tester Lindsay reports this tub should hold up well over time. 

The biggest difference between the Star Treatment and the other cold plunge tubs manufactured by Polar Monkeys is the vertical orientation. Our tester Lindsay admits vertical cold tubs are her preferred way to take the plunge saying, “I love being able to sit upright in a cold tub.”

While the tub appears smaller than the other Polar Monkeys tubs, it has a 110-gallon water capacity and a roomy 33-inch diameter. “I didn’t feel cramped at all. I had space to move around my legs and my arms,” says Lindsay. She also mentions there is a stainless steel seat built into the tub for additional comfort. “The added seat for comfort is ideal because in other barrel-shaped tubs you are sort of standing or holding a mini squat position.”

Speaking of comfort, Lindsay’s main callout for this vertical tub is the stainless steel interior. “It’s hard when you lean back and the edges around the seat are hard,” she says. For this reason, she docks a point and rates Star Treatment 4 out of 5 stars for ergonomics. 

Lastly, Lindsay thinks it’s worth mentioning that the tub sits on 2-by-4-inch wood planks that raise the bottom of the tub off the floor. Before it was filled with water, Lindsay noticed the tub wasn’t level and there was a little wobbling. However, Lindsay was relieved to find that, “When the Star Treatment was filled with water it felt very stable,” she says. 

Other Polar Monkeys Cold Plunge Products

On the Polar Monkeys website, you may be gifted with a free inflatable cold plunge tub at checkout, which is not listed on the website but is a current offering at the time of writing this review. In addition, you’ll also find the following: 

  • Cyber Plunge: Stainless steel cold plunge tub
  • Indoor Sauna: Electric indoor cedar sauna

What to Look for in Polar Monkeys Cold Plunges Products

Based on our experience, customer reviews, and a deep dive into the FAQ webpage, here are some things we think you should keep in mind when shopping Polar Monkeys for a cold plunge tub: 

Insulated tub covers are not included with all cold plunges. However, the brand recommends buying an insulated cover separately (about $350) if you plan to use your cold plunge outside to better regulate the temperature (and to protect against outdoor elements). 

Remember that your electricity usage will go up with a cold plunge tub. The 0.6 HP chillers (Standard option) draw about 8 amps, while the 0.8 HP chillers (Pro option) use 9.5 amps. In comparison, the average refrigerator uses about 10-20 amps.

It’s also worth noting that water can be cooled about 2-6 degrees per hour, but this also depends on the ambient temperature and the chiller use power you choose to buy. 

Lastly, the six-month sanitation kit is $169 from the Polar Monkeys website, which is both chlorine and bromine free. It’s recommended to keep up with cleaning protocols outlined in the user’s manual to extend the life of your plunge tub. 

Brand Policies

You can contact Polar Monkeys via email, phone, or general inquiry form, all of which are located on the brand’s “contact us” page. There is also a live chat feature on the bottom right-hand corner of the website for questions or starting your inquiry. 

Here is what to expect with warranties, returns, and financing options with Polar Monkeys: 


Polar Monkeys cold tubs are all covered by a limited one-year warranty. Essentially this means the brand covers defects in workmanship and materials. A limited warranty usually does not cover normal wear and tear. 

It’s also explicitly stated in the warranty that Polar Monkeys will not cover damage as a result of poor water chemistry, neglected filter care and replacement, freezing conditions, power outages, lack of attention to low water flow, or any other form of neglect, misuse, or abuse. Additionally, the warranty also does not cover commercial use of the product and is intended for at-home use. 


It’s worth noting that Polar Monkeys has a very short return policy lasting only 14 days. If you’re not happy with your purchase, you’d better make up your mind quickly. 

To be eligible for a return the cold plunge has to be new, unused, packed in the original box, and you’ll need proof of purchase. If you decide you need to make a return, initiate the process with an email to info@polarmonkeys.com because items without prior authorization will not be accepted.

Lastly, expect to pay for shipping fees to return the cold tub which will be deducted from the refund. 


At checkout you can use your credit card to make a one-time payment or use one of two express checkout methods: Shop Pay or Google Pay. 

Shop Pay allows you to finance your purchase with a 0% APR 3-month plan or a 36-month plan with 15% interest. Unfortunately, there is no middle ground between 3 and 36 months. 

Final Thoughts of Our Polar Monkeys Cold Plunge Review

Polar Monkeys is highly rated among customers with hundreds of 5-star reviews on the website for each of the tubs we tested. Portal, Brainpod, and Star Treatment all have heating and cooling capabilities to ensure your recovery ritual is customized to your wants and needs.

After testing three cold plunge tubs from the same brand, our tester Lindsay reports the brand offers highly durable cold plunge tubs that are on par for price compared to most other cold plunge tubs on the market with chillers and temperature regulation.
