Inergize Cold & Hot Plunge Tub

Reviewed by
Michal Zucker · Fitness, Movement & Wellbeing Editor
The best hot-and-cold pick: a true 37-107F range and good filtration in a compact, fast-setup package. Accept the inflatable build and it's a lot of versatility for the money.
The Inergize pairs a drop-stitch inflatable tub with an included 1,800-watt WiFi chiller that both heats and cools across a true 37-107F range, all app-controlled. A four-stage filter with ozone keeps water clean, and the whole thing sets up in about 20 minutes. It's the easiest way to get both an ice bath and a hot soak in a small space.

How we know
High confidenceLast checkedGarage Gym Reviews scores the Inergize around 8.1/10 and mindbodygreen tested it for a year, both calling it strong value with a genuinely useful hot-and-cold range (37-107F) and a four-stage filter plus ozone. Reviewers like the ~20-minute inflatable setup and compact footprint for patios. The reservations center on inflatable construction feeling less premium and the chiller adding cost and noise next to the tub.
