Full Review

Overview

The Inergize Cold and Hot Plunge Tub is a customizable inflatable cold plunge that offers both cold therapy and hot immersion in a single portable unit. The drop-stitch construction creates a rigid structure when inflated, and the included chiller provides automated temperature control.

Design and Build Quality

At 25 pounds for the tub, the Inergize is ultra-lightweight. The drop-stitch material creates rigid walls when inflated. The 51-inch by 28-inch by 30-inch dimensions and 80-gallon capacity accommodate most users. The tub is slightly taller than competitors, providing better shoulder immersion.

Cooling Performance

The included chiller cools to 37 degrees Fahrenheit and heats to 105 degrees, controlled via the smartphone app. The 0.5 HP chiller balances cooling performance with noise levels.

Who It Is Best For

Good for users who want an app-controlled portable plunge with hot and cold capability. The included chiller eliminates the need for ice.
