Unpowered tubs & barrels

Cheapest to buy. You supply the cold with ice or a separate chiller.

Ice Barrel

$1,150 - $1,200

The most defensible first cold plunge: ~$1,150, USA-made, a lifetime barrel warranty. You supply the cold.

Portable & inflatable

Inflate, chill, and pack away. Move it or hide it between uses.

Edge Theory Labs

$3,990 - $4,990

A genuinely good portable that inflates and chills in minutes. Held back by a one-year warranty on a multi-thousand-dollar product.

Inergize Health

$4,790 - $5,000

A favorite portable for small spaces and travel. Solid to sit in, but the chiller is modest and the return policy stings.

Powered plunges

A chiller built in that holds temperature for you, set and forget.

Plunge

$1,190 - $6,990

The category leader, from a $1,190 inflatable to a $6,990 hard-shell. Great marketing, real product, the shortest warranty of the premium set.

Sun Home Saunas

$3,999 - $13,999

A well-built 316 stainless Pro that makes its own ice, plus a cheaper portable. Strong hardware, mainstream warranty.

Renu Therapy

$9,699 - $11,999

Beautiful, whisper-quiet Cold Stoic tubs with the best warranty of the powered set. The chiller is on the slow side.

Premium ice baths

Top-of-market build, and the only tubs that form real ice at 32F.

Morozko Forge

$15,500

The only tub that actually forms ice at 32F. Transparent, reliable, and priced for it at $15,500.

BlueCube

$15,999 - $18,999

Handbuilt, commercial-grade tubs trusted by gyms and spas. Unmatched build, top-of-market price.
