Overview
Residential cold plunge with a built-in compressor. Cools to 33°F, ozone sanitation, no plumbing and no external chiller.
The coldest unit in this range and the simplest to install: the compressor is inside the tub, so there is no separate chiller box, no hoses to route and nothing to plumb. It runs on a standard GFCI household outlet.
33°F, which is as cold as water gets
Water freezes at 32°F. A unit rated to 33°F is running at the practical floor, which matters because the gap between 40°F and 34°F is where most of the protocol literature sits. Ambient operating range is -20°F to 120°F, so it will hold temperature in an unheated garage in winter.
Nothing to plumb
Built-in compressor, chlorine-free ozone disinfection and filtration in one shell. The liner is FDA-certified non-toxic material and the unit is heavily insulated, which is what keeps the compressor duty cycle — and the running cost — down.

HOW A SESSION RUNS
A session, start to finish.
Nothing to plumb, nothing to drain, nothing to schedule around.
Set and hold
Set the temperature and let the chiller bring the water down. It is rated to 33°F, so the useful range is entirely yours to choose. Once it is at temperature it stays there, which is the entire argument for a chiller over ice.
Get in
Exhale on entry and keep breathing slowly — the gasp reflex is the part to manage. Two to three minutes is a normal working session; there is no prize for longer.
Get out and rewarm
Dry off and let your body rewarm on its own rather than jumping straight into a hot shower. Shivering is expected and is part of the response.
Rated to run in an unheated garage
