Every Morning Starts at 39°F

A portable cold plunge, cut, assembled and pressure-tested by hand in San Diego. Complete kit $999, free shipping.

Get Your Plunge

Most Portable Plunges Fail the Same Two Ways.

They leak at the seams, or the chiller gives out. Both are the parts that get cheapened when a kit is built down to a price. We cut and assemble the plumbing ourselves, pressure test every kit before it leaves, and oversized the chiller so it isn't running flat out just to hold temperature.

The rows that matter are the first two. Kits fail at the seams or at the chiller, and both are what gets cheapened to hit a price. Those are the two parts we build and test by hand before anything ships.

San Diego Based

Every connection kit is cut, assembled and pressure tested by hand before it ships. Not inspected at the end of a line. Built from parts, on a bench, in San Diego.

That is the part of a cold plunge that leaks, and it is the part most kits cheapen. We would rather do it ourselves and put our name on it.

Frequently Asked Questions

Should I get the complete kit, the tub, or just the chiller?

Three ways in. Nothing yet: the complete kit at $999, which includes everything. Already have a tub, barrel or stock tank: just the chiller at $500. Want to start on ice and add cooling later: the inflatable tub at $400, with the chiller ports already built in.

Is an inflatable actually any good?

Ours is drop-stitch, the same construction used in rigid inflatable boats and high-end paddleboards. At full pressure you can sit on the rim. It insulates better than a lot of rigid shells, does not arrive on a freight truck, and packs away when you want the space back.

Will it hold temperature where I live?

Yes, including through summer. The chiller is 1/2 HP rather than the 1/3 HP most portable kits ship, so it holds 39°F with the room around 100°F instead of drifting up into the 50s. In a mild climate it just runs less to do the same job.

Will I fit?

The tub is 98 gallons and fits users up to 6'7" sitting in a full recline with your legs out, rather than squatting with your knees at your chest. You need about 5 by 6 feet of flat space, including airflow room for the chiller.

How long does setup take?

About 30 minutes, no tools, nothing to glue or cut. The plumbing arrives already cut and assembled, so it comes down to two hand-tight connections. You can watch the full setup before you buy.

Why does the kit arrive in three boxes?

Because moving a 40 lb chiller across the country into a warehouse and back out again costs a few hundred dollars and improves nothing. The chiller and tub ship straight from the manufacturer, and the connection kit ships from our bench in San Diego. Three tracking numbers, no freight truck, and no delivery window you have to stay home for.

What if something goes wrong?

You email us and you get a person. The chiller carries a one-year warranty, and every connection kit is pressure tested by hand before it ships, which is the part that most often leaks on a cheap setup.
