Cold Plunge Guide: 8 Best Cold Plunge Tubs of 2025

Long before the likes of Joe Rogan and Andrew Huberman endorsed it, and Wim Hof the "Ice Man" popularized the cold plunge in modern pop culture, cold water immersion had been a therapeutic practice in various cultures around the world for centuries.

Its origins trace back to ancient Egypt circa 3,500 BC, with Greek physician Hippocrates regarding it as a universal remedy. By the 18th century, even Scottish medical practitioners advocated for its benefits. The age-old practice remains relevant today with cold plunging increasingly gaining traction among athletes and wellness advocates. Look no farther than the advent of the brand Plunge for your best example of how the ritual has infiltrated everyday life.

While the idea of immersing oneself in icy waters may not appeal to everyone, both mental and physical health benefits abound—at least according to diehard cold plungers. I've been embracing contrast therapy with my own backyard sauna and know that if nothing else, one thing that is for certain: the euphoric rush of beta-endorphins delivered post-plunge, coupled with the willpower it demands, grant a sense of accomplishment in our modern, comfort-driven lifestyles.

In a similar vein to outdoor saunas and soaking in a wood fired hot tub, the cold plunge stands as a self-care ritual. In today's digital age, it offers an authentic connection to nature and a break from constant screen time. For those considering this therapeutic journey, now might be the right time to explore cold water therapy and invest in a personal cold plunge pool.

Read on below for a research-driven overview of this chilly activity, answers to key FAQs, and of course, a trustworthy list of the best ice bath and cold plunge tubs for at-home dips.

What Is a Cold Plunge?

A cold plunge is a style of cold water immersion therapy, which benefits the body and the mind. It involves submerging your entire body in chilled water for a few minutes. Cold plunges themselves come in a range of styles, from literall barrels of ice to techy all-in-one tubs with integrated chillers and water cleaning systems.

What Should the Water Temperature Be for a Cold Plunge?

“We recommend 55 to 60 degrees Fahrenheit to start. But anything sub 60 degrees will do the trick. And then one minute to 90 seconds is kind of the minimum viable dose,” says Plunge co-founder Michael Garrett. "After you last this long, a lot of people are able to push through to the two or three minutes because the first minute is just way harder. Once that metabolism gets going you kind of settle in and then you can break through to the three minute mark.”

For a complete wellness route, add in a sauna. This circuit can look like: sauna for 10-15 mins, rest at room temp for 5 mins, cold plunge, rest for 5, repeat.

Are there health benefits of a cold plunge?

There isn’t a definitive answer to whether or not cryotherapy (the application of cold for therapeutic purposes; which includes cold water immersion, among others) is the cure-all many claim it to be. Yet there is a wide range of scientific evidence and personal anecdotes that back up plunging as a legitimate tool to improve your overall health. Consider this your disclaimer.

Physical benefits of cold plunges

Ice baths have long been used in sports medicine, and the majority of medical professionals and experts agree that there are real health benefits to cold plunge therapy, including post-workout muscle recovery and pain relief through a reduction in muscle soreness and decreased inflammation in the body as blood vessels constrict in cold water. (Though some research may suggest otherwise.)

Cold water exposure also alters the blood flow by temporarily redirecting circulation to the organs and away from the body’s peripherals. Evidence has shown that this improves circulation to deeper muscles and tissues (a good thing), improves metabolism and lowers the levels of the possibly detrimental stress hormone, cortisol (also a good thing), but can raise blood pressure and heart rate, which is not helpful to those with poor cardiovascular health. There is no definitive proof of the cold plunge as a miracle immune system booster or weight loss tool.

With this in mind, it is important to view cold water therapy as a component of well-being healthcare. If you have cardiovascular issues, cold exposure is not recommended. In general, it's always a good idea to cold plunge with a buddy and take things slow!

Mental benefits of cold plunges

Do cold plunges improve your mental health? The most notable effects occur immediately after a cold plunge when exposure to the cold temperatures trigger a metabolism boost and the release of dopamine, endorphins, norepinephrine. By regulating the stress response, blocking pain receptors, and influence dopamine levels, a cold plunge can boost your mood and leave you with a tranquil feeling of calm, like a “runner’s high.”

The shock of submerging in cold water also triggers a rush of noradrenaline in the body and brain in tandem with the beta-endorphins. When released, you experience a sudden burst of energy and sense of alertness that absolutely makes you feel alive and ready for action. There is plenty of evidence that shows what a positive impact breathing and meditation can have on the mind-body system. And a promising study has showed a reduction in depressive symptoms and an improvement in mood and anxiety through cold showers and cold water immersion, but it’s certainly no miracle drug.

Bottom line is, cold plunge therapy is not a singular solution to mental and physiological health problems. It can absolutely complement a healthy lifestyle and even enhance certain aspects of your life that contribute to feeling happier and more fit overall, yet there’s a lot more research to be done to prove that point. What is true are the undeniable health benefits of spending time outside and the intrinsic value of seeking out healthy stressors that make our body-mind more resilient and positioned for growth.

Cold Plunge FAQs

How Much Do Cold Plunge Tubs Cost?

Cold plunge tubs can cost as little as as $200 if you opt for a DIY tub method of using a stock tank purchased at a hardware store. Though most made-to-plunge models are around $1,500-$10,000.

Does a Cold Plunge Have the Same Effects as a Cold Shower?

Yes and no. Most showers will drop to between 50-60 degrees Fahrenheit at the coldest. Cold plunge tubs can get down to 32, depending on the model. While the purported benefits are similar, cold plunges are more immersive, and often more conducive to experiencing the mental benefits, if that's what you're after.

Should I Consult with My Doctor Before Cold Plunging?

Most medical experts say yes. A negative shock to the system is possible if cold water exposure triggers a heart arrhythmia that causes the heart rate to slow. If you have cardiovascular issues, it’s not recommended to do a cold plunge. You should also consider plunging with a buddy, especially when plunging outdoors in natural bodies of water, and take it slow if you're a beginner.

Do Cold Plunge Tubs Burn Fat?

That cold plunging for weight loss is a popular claim on social media, there is no confirmed scientific evidence that it actually works.
