The portable cold plunge with a real chiller

Most ship with a 1/3 HP chiller. Ours is 1/2 HP, so it holds 39°F all summer. $999

Get Your Plunge

Portable shouldn't mean underpowered

Inflatable plunges got a bad reputation for a good reason: most of them are sold with a 1/3 HP chiller that cannot hold temperature once the weather turns. We fixed the part that actually matters. Same portability. A chiller that keeps up.

How It Works

  • Step 1: You Pick The Chiller That Keeps Up

    You order the kit for $999. We start hand-assembling your connection kit in San Diego the same day.

  • Step 2: It Ships In Three Boxes

    Chiller and tub come straight from the factory. Your connection kit comes from our bench in San Diego. Three tracking numbers, no freight truck, and no delivery window you have to stay home for.

  • Step 3: Thirty Minutes To Your First Plunge

    Inflate the tub, hand-tighten two quick-connect fittings, fill it and plug it in. No glue, no tools, no plumber. Set it to 39°F and get in the same day.
