INFRADELUX TR150S 4-Person Barrel Sauna

The INFRADELUX TR150S utilizes a curved barrel structure built from Japanese cedar, which helps reduce empty overhead space so the cabin heats up faster and circulates warmth more efficiently than standard rectangular rooms. Cedar is naturally resistant to moisture and decay, making it well-suited for outdoor setups, especially when paired with the included waterproof asphalt shingle roof that sheds rain and snow.

Powering this unit is a 6kW Harvia electric heater, which delivers traditional, steam-capable heat once you add your own sauna stones. Because it runs on a 6kW output, you will need a dedicated 240V electrical hookup installed by a professional electrician. The interior benches comfortably accommodate four adults in a seated position, though two people lying down will find it much cozier.

Assembly is required, and taking your time to level the foundation makes a significant difference in how well the stave joints fit together. The package comes with a handy accessory kit including a bucket, ladle, thermometer, and sand timer, giving you the essentials right out of the box aside from the stones.
