Finnmark FD-1 1-Person Full Spectrum Indoor Infrared Sauna
The Finnmark FD-1 is a compact one-person indoor infrared sauna that pairs UL-listed Spectrum Plus™ infrared heaters with Spectrum Carbon 360 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 in a one-person cabin
Two Spectrum Plus™ heaters sit on the back wall and a third sits under the bench. These dual-wave heaters produce mid and far infrared from an Incoloy outer layer, a ceramic layer, nichrome wire, and a magnesium oxide filling, and are rated for 40,000 hours. Spectrum Carbon 360 panels on both side walls add far infrared with low EMF/ELF technology and 0.99 emissivity. 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. Inside, the cabin is lined with clear A-grade, FSC-certified Western Canadian Cedar, which is naturally antimicrobial. Tongue and groove, double-walled construction with non-toxic wool insulation and an 8mm tempered glass door help keep the heat inside the cabin.
Smart, simple, certified
The V2 control with Wi-Fi lets you turn the sauna on or off from an app on your phone, while the interior LCD display shows the set and current temperature. Bluetooth audio plays through 6" HiFi speakers, and the LED ceiling lights offer color settings with a slow color cycle. The FD-1 runs on a standard 120V / 15A outlet (NEMA 5-15P) with no special wiring, and a dedicated 15A circuit is recommended. 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-1 comes with a 10-year Finnmark Designs warranty on the cabin, plus an unconditional lifetime warranty on the Spectrum Plus™ Incoloy 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-1 is designed for indoor use; using it outdoors without an outdoor cover voids the warranty.
