Cold therapy should fit your life. Not the other way around.
Most cold plunges ask you to give something up. A corner of your home, permanently. A plumber and a weekend of install. Or a freezer full of ice and a new chore every single morning.
It is a self-contained chiller about the size of a carry-on. It turns water you already have into a 37°F plunge, then keeps it cold for days. When you are finished, it rolls out of sight.
The Science-Backed Perks People Actually Feel After Cold Immersion
Plug and play, and we mean it
There is no setup. Hang the hose arm over the side of your tub so the intake sits below the water line. Plug into a standard outlet. Set your temperature. The entire process takes under two minutes.
37°F, on demand, and stable
A 1 HP, 3.5 kW cooling system pulls your water down fast and holds it steady. No babysitting, no topping off with ice, no temperature creep through your session. Set it and forget it.
Works with the tub you already own
This chiller is built for water, not for one specific tub. If your vessel holds 10 (30 L) to 130 gallons (492 L), our chiller chills it. Renters, homeowners, garage gyms, and backyards all work. Nothing is bolted down.
Clean water for months, not one plunge
Built-in ozone filtration keeps your water circulating and clear between sessions. Most owners keep the same water for about a month and refresh once a month, instead of draining after every plunge.
From box to plunge in minutes.

FAQ
Will this chiller work with my tub?
If your tub holds 10 to 500 gallons of water, yes. We have run it with standard alcove tubs, freestanding soakers, inflatable plunge tubs, acrylic spa tubs, barrels, and stock tanks. The hose arm hangs over the side. No plumbing changes.
How fast does it cool?
The powerful 1HP chiller cools your water from room temperature to 38°F in about 40 minutes, making it one of the fastest systems in its class.
Do I have to drain the tub after every plunge?
No. Built-in filtration keeps the water circulating and clean between sessions. Most owners keep the same water for about a month, then refresh.
How cold does it get?
Down to 37°F. You set your target temperature, and the this chiller holds it. Achievable temperature depends on your room temperature, which should be between 50°F and 104°F.
