Our verdict

Roomy enough for two, this ice bath packs down small and sets up in minutes, worth considering if backyard cold plunge space and easy storage matter more than a hard-shell tub.

ASIN: B0CZB38TTXModel: CB03Category: Cold Plunge Tubs

Overview

A soft-sided inflatable cold plunge tub sized at 35.5 x 29.5 inches, built to seat two adults for shared ice bath sessions. It suits home recovery setups for athletes, backyard gyms and anyone doing regular cold therapy without a hard-shell tub.

The eight support legs are rated to 680 pounds and the insulated cover is said to hold cold water near its starting temperature for about 5 hours, which matters more than tub size for anyone doing back-to-back sessions. It folds down with a carry bag for storage or travel, and the same tub doubles as a warm soak since it isn't limited to cold water.

  • 35.5 x 29.5 inch two-person interior
  • Eight-leg frame rated to 680 lbs
  • Insulated cover for extended cold retention
  • Folds flat with an included carry bag

Who it's for

Best suited to people setting up a cold plunge routine at home, in a garage gym, or in a backyard where a permanent hot tub isn't practical. Less useful for anyone wanting a single-person soak, since the extra width is built for two.

Pros and cons

Pros
  • Fits two adults for shared sessions
  • Insulated cover said to hold cold for about 5 hours
  • Folds down with a carry bag for storage or travel
  • Legs rated to support 680 pounds
Cons
  • Soft-sided construction, not a rigid tub
  • Requires periodic water changes and drainage

Performance notes

Setup is inflate-and-fill: the support legs go in, the top ring inflates, and the tub is ready once filled with ice water. The insulated cover is the piece doing the real work between sessions, credited with keeping the water cold for roughly 5 hours rather than the tub material itself. An easy-flow drain lets the water out for periodic changes rather than requiring a full lift-and-dump.
