INFRADELUX TR170S 4-Person Barrel Sauna

The INFRADELUX TR170S is built from Japanese cedar, which offers natural resistance to decay and provides a pleasant, aromatic scent when heated. The round barrel shape is structurally smart, naturally promoting efficient air circulation so the heat rolls evenly from top to bottom rather than getting trapped in the corners. At roughly 65 by 79 inches, the interior bench layout comfortably accommodates four seated adults for social sessions, though stretching out flat is a two-person job.

Driving the heat is a 6KW Harvia traditional sauna heater, a dependable brand staple in the industry. Because it is a 6KW electric unit, it requires a heavy-duty 240V electrical connection—standard household 110V outlets will not cut it. The package includes a waterproof asphalt shingle roof kit, which is crucial for protecting the cedar exterior from rain, snow, and UV rays without requiring you to build a custom overhead shelter.

Assembly is required and typically takes a weekend for two people with basic carpentry skills. The kit comes with handy extras like a wooden bucket, ladle, sand timer, and thermometer, though you will need to source your own sauna stones separately before firing it up. Overall, it is a straightforward, heavy-duty outdoor build designed to last for years with proper exterior maintenance.
