Full Review
Overview
The Hydragun Supertub is a portable inflatable cold plunge that doubles as a hot tub. Built from SGS-certified military-grade marine vinyl, the same material used in military life rafts, it offers surprising durability in a lightweight, portable package.
Design and Build Quality
The double-walled construction uses drop-stitch technology that creates a rigid structure when inflated. At just 21 pounds for the tub alone, it is the most portable chiller-equipped cold plunge we have tested. The 52-inch by 28-inch by 24-inch footprint is compact but sufficient for users up to about 6 feet tall.
Cooling Performance
Available with 0.6 HP ($2,999) or 0.8 HP ($3,999) chiller options. The chiller reaches 37 degrees Fahrenheit for cold therapy and 108 degrees for hot tub mode. A 6-inch touchscreen on the chiller and Tuya Smart app provide precise temperature control.
Maintenance
The triple-layer Permafrost chilling system includes a commercial-grade ozone generator for automated water sanitation. The self-cleaning cycle can be scheduled through the app.
Who It Is Best For
Best for users who need portability, want hot and cold functionality, or live in apartments where a permanent installation is not possible.
