The best cold plunge tubs:

Unless you're a cold shower person, you probably don't subject yourself to freezing water in the name or rejuvenation. But aside from being a shock to the system on a hot summer day, experts say the best cold plunge tubs can actually provide a range of mental and physical benefits—and the science of cold water only continues to grow. 

Looking to buy a cold tub for yourself? We rounded up our top picks, as well as the most compelling evidence that soaking in cold water may actually be beneficial to your overall health.

A few of our fave cold plunge tubs

The Plunge: If you plan to regularly take ice baths, we'd recommend this top-of-the-line pick. The self-automated design keeps water at the optimal temperature for cold water therapy—and the versatile, minimalist design doesn't hurt. Our tester who reviewed the tub struggled to find a flaw beyond the price and limited colorways.

Polar Monkeys Inflatable: For those who simply don't have the space (or desire) to have a cold plunge tub in their home, this inflatable option is a great low-maintenance choice. Once inflated, its built-in chiller cools water to just 36°F. When water is properly maintained, it lasts up to three months like the Plunge.

First seen on Shark Tank, the Plunge tub is a top-of-the-line option for those who want to upgrade their recovery routine. The sleek tub can be safely used both indoors and outdoors, reaching temperatures as low as 39° Fahrenheit. Designed to keep water cool without the addition of ice, it has built-in filtration and sanitation features to help keep your water fresh between baths.

Available in both a standard size and XL size, we love that it has horizontal format that allows you to lay flat for easy submersion. The water also circulates constantly to prevent it from heating up during your 3-minute plunge.

Our tester loved the attention to detail put into each bath; it comes with a protective cover for the outdoors, a skimmer net for debris, and a small branded rubber ducky.

If you want an even more luxurious pick, you can upgrade your tub to an XL for extra space, add hot & cold functioning for versatility, or a pro cooling speed to chill water up to three times faster. (Note: All XL tubs automatically come with a Pro cooling speed).

Regardless of any changes in internal functions, you'll still be limited to the all-white design—which wasn't a favorite of our tester who felt the tub was a start contrast to the greenery outside their home.

Altogether, we're big fans of the Plunge at mindbodygreen, and you can even check our our video review of the Plunge to see the tub in action or read a full breakdown of the Plunge here.

Best portable: Polar Monkeys Inflatable

Save $100 with code:
MBG100
view on Polar Monkeys | $4,200

Pros:

  • Portable
  • Cools down to 36°F
  • Also available with a heating option

Cons:

  • Expensive for an inflatable option
  • Extra maintenance to keep water clean

Coldest temperature:

36°F

Setup:

Inflatable

Dimensions:

53.5" L x 31.5" W x 24" H

Indoor or Outdoor:

Both

Lead time:

6 to 8 weeks

This tub may be inflatable, but it doesn't skimp on features or quality. It comes with a 0.8 HP water chiller, which drops temperatures as low as 36°F. Just remember you will need electricity to power up the cooling attachment.

We consider the Polar Monkeys design the perfect pick for someone who wants all the benefits of a cold plunge tub, but doesn't want to leave one out in the open 24/7. The sleek design doesn't look like a cheap kiddie pool—so you still get the luxury feel—but it's far more affordable than many top-of-the-line picks.

The pool can be set up either indoors or outdoors. Each tub of water can be safely treated and reused for up to three months following the brand's in-depth instructions on a regular maintenance routine. Luckily, there's also a built-in filter to keep the water clean between uses and a pool ozonator to help prevent mold, spores, or bacteria in the water.

Once your tub arrives, you can use the included pump to inflate it. The worst part of the set-up is filling the tub, but the chiller quickly gets into action.

It brings the water from room temperature to below 50°F in about three hours (where the water should stay). Drain the water or use the included cover to store the water for later; it uses about the same amount of power as a refrigerator to keep the water at your ideal temperature.

We love the versatility of the inflatable design—and that it doesn't force you to sacrifice features for something more flexible. Of course, you can also check out the brand's more stationary designs, like the Polar Monkeys Star Treatment, which allows you to control water temperature from your phone.

If you're interested in the perks of heat therapy, you can also upgrade your inflatable chiller to a dual heating system for an additional $200 (an upgrade we recommend).

Best ice bath: Ice Barrel Ice Barrel

Save $175 with code:
MBG175
view on Ice Barrel | $1,200

Pros:

  • Weighs just 55 pounds for easy storage
  • Made from recycled materials
  • Keeps water cool for up to 3 days

Cons:

  • Cannot control temperature
  • No size options

Coldest temperature:

N/A

Setup:

No plug-in required

Dimensions:

42" H x 31" W (opening is 25" W)

Indoor or Outdoor:

Outdoor only

Lead time:

Ships in 3 to 5 days

The Ice Barrel is the ultimate cold plunge tub for someone who wants to elevate their ice bath experience from a regular bathtub, but doesn't want to commit to the maintenance of a glorified mini pool. You simply fill the container with ice and water—that's all!

Of course, the Ice Bath has a few tricks up its sleeve that make it worth the extra investment. Its made in the U.S. from non-toxic yet durable materials. Each barrel weighs 55 pounds when not filled with water and comes with a tiny step stool to let you enter as gracefully as possible (well as smooth as someone entering an ice bath can really be).

Designed for upright sitting position, the barrel shape doesn't require you to lay horizontally to immerse yourself in 105 gallons of water. It also comes with a barrel top that keeps water cool for up to three days after set-up.

Technically the Ice Barrel can be set used both indoors and outdoors—though we think the high water level makes it best suited for outdoor use. It's also available in two color options, and the black model is made from recycled materials (which we love to see). However, one consideration is the size: This tub is only available in one size option, so it may not be accessible to all body types.

Our tester loved that the Ice Barel was small enough to tuck into the corner of the garage. They also felt set-up was incredibly simple, though they opted to add epsom salts for even further benefits from the bath.

Best affordable: WEY&FLY Foldable Bathtub

Pros

  • Portable
  • Affordable
  • Insulated bottom

Cons

  • No cover included
  • May be difficult to get into

Coldest temperature:

N/A

Setup:

Collapsable

Dimensions:

26" H x 30" W

Indoor or Outdoor:

Outdoors or in the shower

Lead time:

Ready to ship

For soaking on a budget, this lightweight option from WEY&FLY is the best option for less than $65. The super compact pick is just over 2 feet tall and 2.5 feet wide, offering just enough space for an adult to sit cross-legged.

The tiny pool doesn't require any inflation; instead you construct the foundation of the tub using included poles, similar to a tent. Once set-up, you can fill with ice and water to create the ultimate relaxing ice bath.

The tub has six layers of material—including a 6mm layer of insulation—to maintain the water temperature during use. When you're ready to replace the water or remove the tub altogether, simply drain and fold up for easy storage.

At only 26 inches high, taller people may find this one more difficult to use, as they'll need to bend their legs or sit cross-legged in order to submerge their body. Also, several reviewers mention a leak near the water release valve, so you'll definitely want to try this tub either outside or in your shower. Still, if you're new to ice baths, testing the waters (literally) in this lower-priced pick might be worth it.

Best splurge: Renu Therapy Cold Stoic

Pros

  • Programmable thermostat
  • Indoor or outdoor use
  • Multiple color and wood options

Cons

  • Expensive
  • Doesn't come with a cover

Coldest temperature:

36°F

Setup:

Can be left on 24/7

Dimensions:

64" L x 34" H x 33" D

Indoor or Outdoor:

Both

Lead time:

6 to 10 weeks

Cold therapy is going bespoke thanks to Renu's lineup of stylish cold plunge tubs. Available in a range of minimalist base and deck colors, the sleek tub is the all-inclusive luxury design for those who want an aesthetically pleasing addition to their home.

Constructed in California, the weatherproof tub can be used both indoors and outdoors. Powerful enough to cool water to 36°F, the Cold Stoic® Standard is fitted with a thermostat to easily control the temperature of your water—which experts say is between 50 to 60°F.

Features like the filtration system and ozone water purification system ensure the water stays fresh between uses (and keeps water maintenance relatively lowkey).

Our favorite part of the Renu is the energy efficient design; the insulated walls can keep water below 60°F for up to 24 hours once the tub is turned off.

Of course, not feature is left forgotten with this tub. It comes with an insulated lid and a handmade matching step stool. You can also choose whether you want a spa light installed for an additional $320.. And, because this is an investment that's intended to last, the Stoic tub comes with a 5-year warranty.

Best foldable: G Ganen Portable Foldable Freestanding Ice Bathtub

Pros:

  • Lightweight, foldable, & easily-portable
  • Surprisingly sturdy for the cost
  • Easy to get in and out

Cons:

  • Some issues with detachable hose

Coldest temperature:

N/A

Setup:

Collapsable

Dimensions:

29" H x 29" W

Indoor or Outdoor:

Outdoors or in the shower

Lead time:

Ready to ship

While this foldable tub is pretty similar to the other affordable option on our list, there are a few key differences that may this design unique enough to call out.

First off, this design is partially inflatable. Instead of putting together rings to create a circle, you simply inflate with air or a pump. This makes the set-up less complex for those who prefer a simpler set-up.

The tub is made from three layers of waterproof and resistant materials: two layers of protective, durable PVC to help maintain the temperature, and one mesh layer. There's also an inflatable armrest and neck support to keep you comfortable. 

You can use this tub indoors or outdoors but, as with the other budget-friendly pick on this list, there are definitely some comments from reviewers about durability and leaking over time. If you do use it indoors, the brand suggests doing so in a shower or anywhere with drainage.

Best durable: Odin Ice Baths The Odin

Pros

  • Sleek cedar design
  • As cold as 32°F
  • Automated filtration and sanitization

Cons

  • Large
  • Must be near an outlet

Coldest temperature:

32°F

Setup:

Can be left on 24/7

Dimensions:

51" L × 49" W × 28" H (larger sizes available)

Indoor or Outdoor:

Both

Lead time:

10 to 12 weeks

The Odin Ice Bath gets as cold as 32°F—so get ready to freeze. In fact, the Odin can even product ice when left on at the lowest temps, which is one unique feat that competitors can't claim.

We'll admit: It's a more expensive option. But you get what you pay for, as this tub as all the bells and whistles. It's not only constructed with beautiful cedar wood, but the tub comes with a fully automated filtration and sanitation system that requires minimal upkeep. (You can even add a UV sanitizer for $500 for even less maintenance.)

We love how little electricity is required to keep this tub running; it uses about the same amount of power as a large freezer. Even better? It's no louder than a standard household refrigerator. However, you will need a refrigeration specialist to come help you set it up before your first use.

Every tub comes with a lockable spa lid, and you'll have the choice to upgrade to the XL size for an extra $2,000. Those purchasing for a commercial space—like a spa or gym—can also invest in the pro model for another $1,500, which increase the power of the chiller to ensure it's up to the strain of consistent use throughout the day.

Best per biohackers: BlueCube Malibu 56 Cold Plunge

Pros:

  • Can be plugged in 24/7
  • Cools to 36°F

Cons:

  • Extremely expensive

Coldest temperature:

37°F

Setup:

Can be left on 24/7

Dimensions:

73" L x 49" W x 28.5" H

Indoor or Outdoor:

Both

We know: The price of this cold plunge tub is not for the faint of heart. But it comes highly recommended by biohacking advocate Joe Rogan who loves this tub for its water circulation. He calls out the Biocube's swirling effect on water, which he says breaks up your body's thermal layer, making the cold plunge that much more effective in his podcast.

And if you have the money to invest, there's plenty to love about this design. The construction is more inclusive, fitting people up to 6'5" and 350+ pounds. It also cools water to just 37°, though beginners can opt for temperatures closer to 60°F.

When left on, the BlueCube uses the same amount of energy as a small refrigerator. It can also be set up both indoors or outdoors—just note that if you do opt for outdoors, the brand says it must be in the shade to avoid damage to the wood surfaces.

Finally, every pool has a 20-micron filter and ozone pool cleaner, which is a chemical-free way to keep water fresh between uses. And if you're paying this much for your cold plunge, we fully expect that use to be every day.

Best for small spaces: The Pod Company Ice Pod Pro Bundle

Pros:

  • Pump included to keep water flower
  • Comes with floating thermometer
  • Insulated lid keeps cool

Cons:

  • Must fill with ice

Coldest temperature:

Dimensions:

The Ice Pod Pro is a newer launch—and the affordable design fills a gap in the market for those who still want a high quality product but don't want to spend a fortune on a luxurious tub.

The portable pod is similar to many budget options, with a plastic legs around the tub and an inflated rim. However the actual materials differ from many affordable options thanks to a focus on quality. The inner lining is made from a BPA-free waterproof lining, the insulation layer has sub-zero cooling technology, and the durable exterior is UV resistant.

Other differentiators for the Ice Pod Pro include a water flow pump—which circulates water to prevent your body heat from warming the water or the ice from freezing solid—and a floating thermometer to monitor the temperature to reach the perfect 50 to 59 degree Fahrenheit range. (Both accessories come with the Pro Bundle.)

We also love that the Ice Pod Pro has an insulated lid that keeps water cold for a few days; the standard version only promises to keep the water cool for up to 24 hours. If you don't plan to use your ice bath often—or don't want to set it up outdoors—we recommend that you opt for the standard option, which only costs $150.

What is a cold plunge tub?

Although you could create a makeshift cold tub in your bathroom with a bath full of ice, a proper cold plunge tub is exactly as it sounds: specifically designed to support colder temperatures of water that will shock the system and offer your body a range of benefits. 

"Used as a recovery method, the water should probably be under 10°C," suggests cold therapy expert Mark Harper, M.D., Ph.D. "But just to get the cold buzz without quite so much discomfort, temperatures of over 10°C (and even up to 20°C) will have most of the effect with much less pain," he adds. Note: 10°C is 50°F.

How do cold plunge tubs work?

The process of how a cold plunge tub cools the water (and keeps it cool) depends on the design of that particular tub. Some higher-value cold plunge tubs, such as The Plunge, have a pumping chiller attached, which keeps the water circulating, pumping it out to chill it and then pumping it back in. The Plunge brand says this method also helps users feel colder sooner, as the heat is being pulled away from your body by the moving water.

Other cold plunge tubs, such as the portable, foldable, and affordable options on our list, do not offer this water circulation and pumping, but are made from durable materials that help trap in the heat. While every cold plunge tubs works in a slightly different way, the general idea is the same. These tubs are designed to support cooler temperatures that put your body into a temporary state of stress.

Benefits of a cold plunge tub

If you're skeptical about subjecting your body to freezing temperatures in the name of wellness, know there's actually some compelling evidence in its favor. "In simple terms, regular use will reduce inflammation and the body's reaction to stress. Putting your face—it doesn't even have to be the whole head—in will have an almost immediate effect," explains Harper. 

On the topic of stress, intentional cold exposure (as in a plunge pool) is a form of hormetic stressor. In layman's terms, this is the good kind of stress that actually helps your body to adapt and stay fit and healthy. When you spend a short burst of time each day with an acute stressor like cold water, your body is taken out of homeostasis and your cells are activated to promote stress resilience, repair cellular damage (through processes like autophagy), repair DNA, reduce inflammation, and more.

In fact, some experts believe that missing out on hormetic stressors can actually hold you back. "Biologically, the lack of acute stressors prevents the intermittent episodes of cellular 'housecleaning' activities that slow aging," Elissa Epel, Ph.D., director of the University of California–San Francisco Aging, Metabolism and Emotion Center wrote in a 2020 research review1.

Additionally, shocking your body with a switch between hot and cold extremes can also improve your health, as longevity expert and Harvard geneticist David Sinclair, Ph.D., explains on the mbg podcast. "Sauna protects you against heart disease if you do it regularly, and cold plunges are increasingly thought to be helpful. What [they do] is activate the production of brown fat, which exists mostly in your back. Brown fat puts out signals that increase your metabolism," he explains. 

As for the mental benefits, Jono James, cold-water immersion expert and CEO of Odin Ice Baths shared that voluntarily placing yourself in uncomfortably cold temperatures can help build fortitude. "You're purposely putting yourself in quite a bit of pain because the ice bath is not a pleasant experience, but because you're choosing to do it, it gives you a sense of empowerment. Since it's a choice, it also means you're more resilient to things that are out of your control because you're choosing to put yourself in this uncomfortable position," he shares.

A quick summary of potential cold plunge tub benefits
  • Promotes stress resilience
  • Repair cellular damage & DNA
  • Reduce inflammation
  • Slow aging

Do cold plunge tubs burn fat?

The are many proven benefits of an ice bath—and a few potential benefits of taking a cold plunge that still need to be explored further. Weight loss falls into the latter category.

A study published in Scientific Reports found stem cells subjected to cold temperatures formed brown fat that can increase calorie burn2. Research on mice shows similar results of brown fat activating in cold temperatures3. Data also suggests that ongoing cold exposure can help convert white fat into metabolically healthy beige or brown fa4t.

As functional medicine expert, Laura DeCesaris previously told mindbodygreen, "More data needs to be seen as to possible long-term metabolic impacts of cold immersion over time." She says sporadic sessions are unlikely to improve results—and it's important to remember that an increased metabolism won't lead to weight loss if appetite and calorie consumption also increases.

Are ice baths good for you?

Sure, putting your body through stress may sound counterintuitive—but this is actually a good kind of stress. Whether you're investing in a cold plunge tub for your home, or you're making your own ice bath, you're not going to solve every health problem you've ever had. That said, when performed regularly and correctly, the practice has a slew of health benefits, explained in-depth below. If you're not sure if ice baths are a good idea for you, check with your doctor before adding the practice to your routine.

Who shouldn't take an ice bath?

Experts previously told mindbodygreen that people with high blood pressure should skip cryotherapy. Cold water causes your blood vessels to constrict, which increases heart rate, blood pressure, and respiratory rate. Typically the body can compensate for this constriction, per longevity expert Seema Bonney, M.D., but it may be harder for those with high blood pressure or cardiovascular disease.

FAQ

Is there any risk associated with cold plunge tubs?

Of course you should be aware that cold temperatures can be jarring to the body, but on the whole if you’re listening to your body and being smart about how long you’re staying in the tub, experts say it should not pose a risk to your health. 

“It’s important to get the body used to the temperature (a minute or two) before putting your face in," suggests Harper. "And there is nothing to be gained and all to be lost by staying in so long as to become hypothermic. This is dependent on temperature: under 10°C, three minutes is sufficient. But even at 20°C, no more than 10 minutes is necessary."

Who could benefit from a cold plunge tub?

Even if you're not an intense athlete, anyone could benefit from the use of a cold plunge tub. That said, they are a great means of physical recovery after working out. "The reduction in inflammation and the attenuation of the stress response are universally positive," says Harper. 

Who should not do cold plunge?

As with all new health practices, it’s recommended to check in with your doctor before adding a cold plunge to your routine, especially if you have an existing medical condition.

Is a cold plunge worth it?

Adding a cold plunge to your routine has many physical and mental health benefits. Cold plunging can promote stress resilience, repair cellular damage (through processes like autophagy), repair DNA, reduce inflammation, and more. As our expert explained, you don’t have to dive right in. Start slow and as you begin to acclimate to the practice and experience the benefits, you’ll see that cold plunges are worth it.

What's the easiest cold plunge tub to take care of?

A cold plunge tub with a built-in sanitation will be the easiest to take care of. The Plunge, Renu Therapy Cold Stoic, and Odin Ice Bath all come with built-in water filters and ozone sanitation systems. These system replace chemicals with powerful oxidizers that break down unwanted contaminants, like mold and bacteria, to keep your water fresh between plunges.

The takeaway

For metabolic, energy, and mental health benefits, regularly soaking in a cold plunge tub can be an excellent way to invigorate the system and support overall well-being. A cold plunge can help with inflammation and act as a great start to the day or help you recover from a particularly strenuous workout. If you're in the market to invest in your health, consider taking home the Plunge for a top-of-the-line pick or try the slightly more affordable Polar Monkeys Inflatable.
