How it Works

HomePlunge is different from the typical Cold Plunge as it is designed to be used with your existing home bathtub unlike an outdoor permanent installation.
- Hidden water tubes - Patented and award-winning water transfer device. The inlet and outlet water hoses are concealed in a bend-and-stay insulated arm.
- Instant Setup - The hose-arm CLICKS into the top of the chiller making an air-tight vacuum seal. No fasteners, no plumbing. Press the button to release and stow away.
- Ready when you are - Put the hose-arm into the tub water. Set your temperature from the touch screen. Come back after your coffee and cold plunge.
