The Finnmark Trinity™ FD-6 is a 6×6 outdoor hybrid barrel sauna, built from 1.5" thick FSC™ certified Western Canadian Clear Cedar — antimicrobial, naturally aromatic, and selected for long-term outdoor durability. Five Spectrum Plus™ UL listed short-wave infrared heaters operate on a standard 120V outlet, while a separately purchased 240V traditional heater (up to 6kW) adds rock sauna capability. With both systems running simultaneously, the barrel reaches up to 185°F.

The 8mm solid tempered glass door and window panels bring natural light into a two-tier cedar bench interior. A Wi-Fi Controller 2.0 LCD panel with Bluetooth audio and lighting controls handles remote operation and ambiance. Three stainless steel bands provide corrosion protection, and Shou Sugi Ban torched supports offer long-term rot and decay resistance. Shingle roof with moisture barrier completes the weather-ready build.
