Eliminate the expensive dedicated outdoor tub - use your existing bathtub and cold plunge with privacy. The H3 will have your water cold before you finish your morning coffee.

Never miss a day due to the weather outside. Speed up muscle recovery, reduce inflammation, and improve sleep quality. Consistent cold therapy delivered right in your own bathroom — available whenever your body needs it most.

On a tight schedule in the morning? Want it ready for you after your activity? Schedule your system or turn it on from the car on the way home from the gym. 

H3 won at CES and TIME's Best Innovations in its debut year, 2025.

Don't spend hundreds on monthly cleaning kits and more importantly, your time, on pH testing your water when instead you could simply drain the tub.
