I-THERA-U has built a portable sauna that combines two distinct therapies in one compact frame. The 34 x 34 x 72 inch enclosure houses 324 total light beads—108 visible 660nm red light diodes and 216 invisible 850nm near-infrared diodes. That split matters. The red light works on skin surface and muscle tissue, while the deeper-penetrating NIR targets cellular recovery. Together with the steam heat, you get a session that promotes circulation and relaxation while addressing recovery at a deeper level than a standard steam sauna alone.

The unit weighs just over 18 pounds, which makes it genuinely portable. You can set it up in a bedroom, home gym, or even pack it for travel. The included lithium polymer battery means you don’t need to stay tethered to a wall outlet. Heat-up time is quick, and the steam function produces consistent, soothing warmth without the intensity of a traditional far-infrared sauna. The chair inside is simple but adequate for sessions up to 30-40 minutes.

One practical note: at 34 inches wide, the footprint is manageable but still requires a clear corner or dedicated spot. The fabric construction feels durable for home use, though frequent folding and unfolding may wear the zippers over time. If you want targeted light therapy paired with heat in a package you can move room to room, this setup delivers on both fronts without compromise.
