The Plunge All-In is the tub we point most people to first, and it's our Best Overall cold plunge. It isn't the coldest or the cheapest — it's the one that's easiest to actually live with, which is what turns cold plunging from a phase into a routine.
What it is
The All-In is Plunge's flagship: an acrylic laydown tub with the chiller, pump, and filtration all contained in one unit instead of bolted on as a separate box. It cools to about 37°F, runs a 20-micron filter plus ozone so the same water stays clean for weeks, and is controlled from the Plunge app. A Hot & Cold version adds heating up to 104°F if you want contrast therapy in the same tub.
What's good
- It's genuinely low-hassle. Plug-and-plunge setup, no plumbing, and filtration that means weeks between water changes rather than draining every few uses.
- Comfortable and easy to use. The acrylic shell is warm to the touch and the laydown shape makes entry and exit easy — small things that decide whether you keep at it.
- Strong cooling. 37°F is cold enough for the full cold-shock dose; you're not waiting around or fighting the chiller in summer.
- Best support in the category. Reviewers consistently rank it at or near the top — Fortune and BarBend have scored it around 95/100 — and the brand's service network is the deepest here.
What to watch
- It's expensive, and the Hot & Cold version pushes well past $9,000.
- It's big and heavy. Plan the footprint before you buy; this is not a tub you'll move on a whim.
- Cooling-only on coldness. If you want sub-37°F water and ice formation, the Sun Home Cold Plunge Pro goes colder — see the head-to-head.
Who it's for
Buyers who will plunge several times a week and want the least friction possible. If you're still testing whether the habit sticks, don't start here — start with an ice setup like the Ice Barrel 400, or a value chiller like the Hydragun Supertub, and graduate up.
The bottom line
The Plunge All-In is the most complete all-around cold plunge: fast cooling, easy maintenance, optional heat, and the best support — worth it if you'll plunge often and want zero hassle. Confirm it fits your space and budget with the cold plunge quiz, and if room is tight, check best cold plunges for small spaces.
