iTHERAU’s infrared sauna is designed for two people who actually want to sit together without feeling cramped. At 71 inches tall and 49 inches wide, the cabin gives each person enough shoulder room to lean back comfortably. The 41.3-inch depth means you’re not knocking knees with your partner. It’s a genuine side-by-side setup, not a tight squeeze.

The dual 1400-watt steamers push heat evenly through the cabin. You get 360-degree steam distribution, so the air warms up in minutes rather than waiting through a slow preheat. The 3-liter tank capacity is enough for a full session without refilling. Red light therapy panels are built into the unit, adding low-level light exposure that some users find helpful for muscle recovery. The entire sauna weighs just 29.5 pounds, which makes assembly and repositioning far easier than the 200-pound cedar boxes you might have hauled before.

One honest limitation: the lithium polymer battery is listed as required and included, but that’s likely for a control panel or remote, not for heating. The sauna needs a standard wall outlet. If you’re expecting a plug-and-play setup that runs off-grid, this isn’t that. For home use, though, the combination of infrared heat and red light therapy in a genuinely roomy two-person package is a practical upgrade from a solo pod.
