Same award-winning system. Same plug-in setup. Two different chillers — one tuned for speed and power, one for compact spaces and a quieter footprint. Here's how they compare to each other, and to the alternatives.
CES Innovation Award winner. Maximum power, fastest chill times — for athletes, daily plungers, and larger tubs.

The 1/2 HP chiller. Smaller, quieter, and more accessible — designed for tighter bathrooms and first-time plungers.
0% APR · Free shipping · Accessories included
20–30°F per hour means a 34°F tub before your coffee is done. Built for athletes and daily protocols where every minute matters.
Set it from the app on your way home. Bella chills steadily in the background — perfect when "ready when I am" matters more than raw speed.
34°F target, dialed in 1°F increments. For full deep-cold protocols and the lowest end of the temperature range.
Smaller, lighter, whisper-quiet — and engineered to live happily in apartments, condos, or any tight footprint where the H3 won't quite fit.
1 HP of compressor delivers full performance even in oversized soaking tubs. More water, same chill window.
The most accessible way into HomePlunge — same award-winning system, lower entry price, and a quieter experience as you build the habit.
Cold plunging used to mean a $5,000+ permanent fixture or a freezer's worth of ice every morning. HomePlunge replaces both with a chiller you roll into a closet when you're done.

Bella holds your water down to 41°F — cold-plunge cold by every clinical definition. H3 reaches 34°F, the deepest end of the cold-plunge range, in 1°F increments.
If you're targeting deep-cold protocols (sub-41°F) or you train at the lowest end of the temperature curve, choose H3. For most plungers — and anyone targeting a comfortable 50–55°F session — Bella is the right number.
H3 chills at 20–30°F per hour — a typical bathtub goes from warm to plunge-ready in 45–60 minutes. Bella runs at roughly a third of that rate (6–10°F per hour), with most tubs reaching plunge temperature in 2–4 hours.
If you usually plunge on demand, H3 fits the rhythm. If you tend to schedule sessions in advance — set it from the app, plunge when you walk in the door — Bella will be waiting either way.
Dedicated plunges run $5,000–$10,000+, take up 4′ × 8′ of permanent floor space, and often need new electrical. They're great if you have the room and the budget.
HomePlunge starts at $1,899, uses the bathtub you already own, plugs into a standard outlet, and rolls into a closet when you're done. Same therapeutic cold — none of the bathroom remodel.
No. Both H3 and Bella simply dip into the water in your existing tub via the click-on hose-arm — there are no physical connections to your plumbing, no faucet adapter, and no permanent install. Fill the tub, drop the arm in, press start.
H3 runs at 65–75 dB during operation — typical for a residential chiller. Bella's 1/2 HP compressor is meaningfully quieter and was specifically engineered for apartments and bedrooms-adjacent bathrooms where sound matters most.
Both run only while actively cooling — usually under an hour per day once water hits target temperature.
Both ship with the chiller, the click-on hose-arm, the smart-app login, and a 1-year manufacturer warranty (extendable up to 4 years with SureBright at checkout). Free U.S. shipping. 0% APR financing via Affirm.
