SaunaBox® SmartSteam Pro V2

The traditional sauna experience has always come with strings attached — a gym membership, a spa visit, or a permanent home installation that costs as much as a used car. The SaunaBox® SmartSteam Pro cuts all of that out. It's the original at-home portable steam sauna, refined over multiple generations and now trusted by professionals and everyday athletes alike, setting up anywhere in your home in about 15 minutes.

Steam heat isn't just hot air. The SmartSteam Pro reaches 130–140°F with near-100% humidity — and because water carries heat energy far more efficiently than dry air, that translates to a physiological experience comparable to a dry sauna running 30°F hotter. You get deep sweat, elevated heart rate, and real recovery benefits at temperatures your body can handle longer. Seven heat levels and a 0–60 minute timer give you precise control over every session.

What sets the SmartSteam Pro apart from cheaper competitors is its materials story. Every component — the ThermoShield tent, silicone tubing, and steam chamber — has been independently tested for microplastics, heavy metals, phthalates, and volatile organic compounds. It's the only portable steam sauna that is Certified Microplastics Free by Simple Lab®, California Prop 65 compliant, and RoHS certified. When you're sitting inside a steam environment, what your sauna is made of matters — and we have the test results to prove it.
