TS37-104 Cold Plunge with Integrated Chiller/Heater
One-Piece Cold Plunge Tub – The Ultimate Full-Body Recovery System
Discover the power of cold therapy with our premium one-piece cold plunge tub, thoughtfully designed for maximum results with minimum setup. Whether you're focused on peak performance, accelerated recovery, or daily wellness, this plunge is your solution.
Boost Recovery & Relaxation
Cold therapy helps promote faster muscle recovery — highly beneficial after intense training, long days, or stressful routines.
Even a short dip in cold water activates the release of endorphins and norepinephrine, improving mental clarity and elevating mood, and may even improve your sleep.
Hot Soak Option for Ultimate Flexibility
With a wide temperature range from 37°F to 104°F, you can switch between cold plunges and warm soaks based on your body’s needs. It takes the tub several hours to go from its coldest setting to its hottest in most environments, so it is best used one way or the other for an extended period. The heater is very useful if for example, you want to have the cold plunge be at 60°F when it will be below 60°F outside.
Clean Water, Always
The powerful dual-filtration system combined with ozone purification keeps your water fresh and clean.
Plug-and-Plunge Simplicity
No need for special wiring, plumbing, or hours of installation. Just plug into a standard 110V / 15-amp outlet, fill and chill, and you're ready to go.
Insulated for Performance & Efficiency
The fully insulated design maintains your desired temperature longer and minimizes energy use — whether you’re keeping it ice cold or soaking warm.
Spacious & Comfortable
The single-piece tub offers generous space to fully immerse — ideal for taller users or those who prefer an open, comfortable plunge.

- Insulated cover
- Drip tray
- Drain valve attachment with garden hose thread, attaches to the port on the left side of the tub

The power cable comes out of the service panel end. We recommend that you put the service panel end of the tub at least 16" away from a wall or anything else, and the side with the drain port 12" away from anything else so you can easily install the drain attachment if you need to drain the tub. The tub will generate some condensation depending on the environmental humidity so it must be placed on waterproof flooring, or just somewhere that will not be damaged by water.

“It feels like adding cold plunging has really helped me fit more work into my weightlifting routine. I feel like I have fewer days where I struggle on a lift, even keeping the same volume.”
