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.
How is the water kept clean?
A 3-stage ozone purification system maintains clear, bacteria-free water with minimal maintenance.

I didn’t want to buy a whole new cold plunge, so I went with the Modouge chiller and connected it to a tub I already had. Setup was pretty straightforward and the 1 HP chiller gets the water nice and cold. I’ve been using it several times a week and so far it’s been working great.
