When it comes to cold tub at home, there are plenty of ways to go about it at home. You can take cold showers, submerge your legs or feet in a tub of cold water, or even try a cold plunge at a gym or physical therapy facility. But if you want to take your cold-water immersions to the next level, a dedicated tub is the way to go.

You can purchase tubs made specifically for ice immersion, like the Lincoln, California-based Cold Plunge model that allows you to control the water temperature as low as 39 degrees Fahrenheit. Other companies, such as Ice Barrel, offer lightweight barrels that can be used indoors or out, and have insulating features that keep the water cold for longer periods of time.

The Cold Tub Revolution: Why Every Home Needs One

Whether you’re looking for something to use daily or just on occasion, these options are worth considering—if you can afford it. The price tags vary, but they’re generally comparable to high-end saunas or steam rooms, with some offering free shipping and warranties.

When choosing a cold tub, be sure to look for a tub that’s easy to drain and has a built-in filtration system. The most expensive options also feature internal cold regulation to ensure that the water stays at an optimal temperature. To help prevent frostbite or hypothermia, you should wear protective clothing, such as swim trunks, shorts, or a swimsuit, and foot booties. You can also wear a sweatshirt to cover your genitals and torso, or even just a pair of socks and shorts if you’re only submerging your lower half.
