HomePlunge Bella — 1/2 HP Cold Plunge Chiller for Your Bathtub

About the HomePlunge Bella

The HomePlunge Bella is a compact cold plunge water chiller that transforms your bathtub into a personal cold therapy station — no ice, no dedicated tub, and no plumbing required. Designed as the streamlined entry point in the HomePlunge lineup, the Bella delivers real cold plunge performance in a smaller, quieter, and more affordable package that fits seamlessly into everyday life.

How It Cools

The Bella is powered by a 1/2HP compressor that circulates and chills your bathwater steadily and efficiently. It won't race to temperature quite as fast as its bigger sibling, the H3, but for most standard bathtubs you're still looking at cold plunge–ready water well within a reasonable window — especially if you schedule your session in advance and let the Bella do the work while you go about your routine. Digital temperature control lets you set your target anywhere down to 37°F and the Bella holds it there with precision. No thermometer guessing, no temperature swings, no ice melt math.

Why a Chiller Instead of Ice

Anyone who's tried a DIY ice bath knows how quickly the novelty wears off. Buying ice in bulk is expensive. Hauling it from the car to the tub is tedious. And even when you get it right, the temperature is wildly inconsistent — it spikes the second you sit down and shifts unevenly as the ice melts at different rates across the tub.

The Bella eliminates all of that. It delivers consistent, repeatable cold water at the exact temperature you choose, session after session. The built-in smart app lets you schedule cooling in advance, so your bath can be chilled and waiting before you wake up or right when you walk through the door after a workout. No prep, no cleanup, no daily ice runs. Just step in.

And over time, a chiller costs less than ice. A single bag gets you one session. The Bella runs on standard household electricity with a modest energy draw — its smaller compressor sips power, often using less energy per day than a space heater running for an hour.

Setup and Portability

If you're short on space, the Bella was made for you. It requires zero plumbing modifications — two insulated hoses connect the chiller to your tub using a simple faucet adapter, and the unit plugs into a standard wall outlet. Setup takes minutes, and nothing about the installation is permanent.

The Bella's smaller footprint makes it ideal for apartments, small bathrooms, and rental homes where space is tight and permanent equipment isn't an option. When you're done, disconnect the hose-arm with a button and tuck the unit into a closet, under a sink, or behind a door. It's one of the most portable cold plunge chillers on the market — designed to disappear when you don't need it and perform when you do.

Built-In Filtration

The Bella includes a built-in reusable water filter that keeps your bathwater clean between sessions. It captures particulates and maintains water clarity, so you're not draining and refilling after every use. When the filter needs attention, just rinse it — no replacement cartridges to order, no recurring filter costs. When the water has run its course, drain the tub and start fresh.

The Benefits of Cold Plunging at Home

Cold water immersion is used by professional athletes, physical therapists, and wellness practitioners around the world — and the body of research supporting it continues to grow. Regular cold plunge sessions are associated with faster muscle recovery after intense training, reduced inflammation and joint soreness, a measurable boost in dopamine and norepinephrine that supports mood, energy, and mental clarity, and improved sleep quality when practiced consistently.

The barrier has always been access. Gym plunge pools have limited hours. Cryotherapy sessions are expensive. Ice baths are a hassle that most people abandon within weeks. The Bella removes every obstacle by bringing cold therapy into the space you already have — your bathroom — at a price point and size that make it easy to commit.

Who the Bella Is For

The HomePlunge Bella is built for anyone who wants the real benefits of cold water immersion without the bulk, the noise, or the premium price tag of a full-size chiller. That includes first-time cold plungers looking for an accessible way to build a consistent practice, apartment dwellers and renters who need a compact and portable solution, athletes and active individuals who want reliable post-workout recovery at home, and wellness-focused individuals incorporating cold exposure or breathwork into their daily routine. If you have a bathtub and a standard outlet, you have everything you need to start cold plunging today.

HomePlunge Bella vs. HomePlunge H3

Not sure which model is right for you? The Bella and the H3 share the same core technology — digital temperature control, smart app scheduling, built-in filtration, and zero-plumbing setup. The difference comes down to size and speed. The H3's 1HP compressor cools faster and is built for users who want the quickest possible cooldown or who are running larger tubs. The Bella's 1/2HP compressor takes a bit more time to reach target temperature but runs quieter, draws less power, and fits into tighter spaces. If you plan ahead and schedule your sessions, the Bella delivers the same cold plunge experience in a more compact and budget-friendly package.
