DIY Cold Plunge Kit with Heating (1 HP)

  • Build Your Own Cold Plunge!

Transform your existing tub or tank into a cold plunge and hot tub with the DIY Cold Plunge + Hot Tub Kit by Chilly.

The kit includes everything you need — a powerful cooling and heating unit (including pump, UV ozone, and filtration), tubing, and the fittings to convert your existing bath tub or water tank. No more buying ice every day: simply plug it in and enjoy energy-efficient, perfectly cold (or hot) water 24/7, or any time you want it.

All purchases include plans, parts lists (including the tubs we use), and instructions (normally $200) on how to build your own luxury cold plunge that's identical to our Chilly Bath cold plunge for less than $1,000 in extra parts and 5-6 hours of easy labor.

The Bathtub Conversion Kit includes the chiller, hoses, and suction cups to temporarily turn your home bath tub into a cold plunge, no drilling required.

The Tank Installation Kit includes the above, as well as drill bits and fittings to turn any water vessel (e.g., tub, stock tank, Rubbermaid) into a permanent cold plunge.
