Find your chiller
H3 or Bella?
Four questions. Both turn the bathtub you already own into a cold plunge, so this is only about how cold you want to go, how fast, and how much room you have.
Question 1 of 4
How often do you plan to plunge?
When do you want the water cold?
How cold do you want to go?
How much room does the chiller have?
The HomePlunge H3
The flagship. 1 HP of compressor pulls a typical bathtub down at 20 to 30°F per hour, so you are plunge-ready in 45 to 60 minutes, all the way to 34°F in 1°F increments. Built for daily use, deep cold, and larger tubs.

The HomePlunge Bella
The compact one. A 1/2 HP compressor chills at 6 to 10°F per hour, so most tubs reach plunge temperature in 2 to 4 hours, down to 41°F. Smaller, lighter, and engineered for apartments and tighter bathrooms.
