Finnmark 4-Person FD-6 Combo Hybrid Barrel Sauna

Step into a sauna experience like no other with the Finnmark FD-6 — a 4-person cedar barrel sauna that combines the charm of traditional steam with the innovation of advanced infrared technology. Built from premium 1.5" thick Canadian Cedar staves, this outdoor retreat is as beautiful as it is durable, filling the air with a naturally soothing cedar aroma every time you step inside.

The interior features dual-level benches and backrests made from satin-smooth, antimicrobial cedar, designed for comfort even in high heat up to 185°F. Whether you’re enjoying the classic steam experience with the 4.5kW heater or switching on the Finnmark Spectrum Plus™ infrared system, you’ll feel the deep, detoxifying sweat—up to 25 times more effective than standard carbon saunas.

Thoughtful details like an 8mm tempered glass door, matching side windows, and a weatherproof shingle roof add to the luxury. With built-in Wi-Fi controls and customizable under-bench RGB lighting, the FD-6 gives you total control of your relaxation—right in your backyard.

Your Thermory Barrel Sauna comes with our step-by-step installation guide. And there’s no cutting necessary, thanks to our pre-cut and pre-milled staves and cradles.
