Finnmark FD-2 2-Person Full Spectrum Indoor Infrared Sauna
The Finnmark FD-2 is a two-person indoor infrared sauna that pairs UL-listed Spectrum Plus™ infrared heaters with Spectrum Carbon far infrared panels and near-infrared LED ceiling lights. It plugs into a standard 120V household outlet, heats up to 170°F in under an hour, and is built with a Thermal Plus™ European Aspen exterior around a clear A-grade Western Canadian Cedar interior.
Full spectrum heat for two
Four Spectrum Plus™ heaters surround the bench: two on the back wall, one under the bench, and one on the front wall beside the door. These dual-wave Incoloy heaters produce mid and far infrared, carry 0.99 emissivity, and are rated for about 40,000 hours. Spectrum Carbon panels on both side walls add long-wave far infrared with low EMF/ELF technology and are rated for about 30,000 hours. Near infrared comes from the Spectrum LED ceiling lights, so all three ranges work together in one session.
Thermal Aspen outside, cedar inside
The exterior is Thermal Plus™ European Aspen, a wood that is heat and steam treated with no chemicals and is made to resist rot, warping, decay, and chipping. The walls, bench, and backrest inside are clear A-grade Western Canadian Cedar, which is naturally antimicrobial and mold resistant. Tongue and groove, double-walled construction with non-toxic wool insulation and an 8mm tempered glass door help keep the heat inside the cabin, and an ergonomic cedar backrest makes longer sessions more comfortable.
Smart, simple, certified
The V2 controller with Wi-Fi lets you start the sauna from an app on your phone, while the interior LCD touchscreen controls temperature, lighting, and music. Bluetooth audio plays through 6" HiFi speakers, and the LED ceiling lights add color therapy across the bench and backrest. The FD-2 runs on a standard 120V / 15A outlet (NEMA 5-15P) with no hardwiring, on a dedicated 15A circuit. The cabin is ETL certified, the Spectrum Plus™ heaters are UL listed, and EMF levels are third-party tested. You can review the test log and certificates in the documents below.

Warranty basics
The Finnmark FD-2 comes with a 10-year Finnmark Designs warranty on the cabin, plus an unconditional lifetime warranty on the Spectrum Plus™ heaters. Outdoor and commercial use are each covered for 5 years. For infrared saunas in the USA, "lifetime" is considered 7 years.
Coverage conditions
The sauna must be installed and maintained as instructed. The FD-2 is designed for indoor use; using it outdoors without an outdoor cover voids the warranty.
