After taking a deep dive into the portable steam sauna market, I’ve found that the best portable steam sauna is the Durherm portable folding home steam sauna. With a timer allowing up to 60 minutes of 800W energy, this sauna is capable of steam up to 113F, or 45C.
It’s compact, quick to set up, and easy to use, making it the best portable steam sauna.
