The Finnmark FD-2 Full-Spectrum Infrared Sauna is a 2-person full-spectrum infrared sauna measuring 44" (111.7 cm) wide × 48" (121.9 cm) deep × 78" (198.1 cm) high, running on a 120V 15A supply. It reaches 170° F on infrared.
The only infrared saunas in the industry that combine UL Listed Spectrum Plus infrared heaters with Spectrum Carbon 360° panels, allowing you to reach temperatures of 170° in less than 1 hour on a standard home outlet - an engineering marvel. Finnmark Designs is the only infrared sauna manufacturer that combines long-wave carbon 360 infrared panels with UL listed short-wave Spectrum Plus infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and an experience better than any other sauna.

Finnmark states the cabin is ETL certified and that the short-wave Spectrum Plus infrared panels are UL listed. Ask us for the certificates if your inspector or insurer wants to see them.
The FD-2 Full-Spectrum Infrared Sauna seats 2. Interior 44" (111.76 cm) × 40" (101.6 cm) × 70" (177.8 cm); exterior 44" (111.7 cm) × 48" (121.9 cm) × 78" (198.1 cm).
Measure the exterior against your space, and the door against the route you will carry the panels through. The cabin arrives flat as panels, so the constraint is usually the doorway rather than the room.

What Finnmark publishes about infrared heat. These are the manufacturer's claims, not medical advice.
- The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna. As a result, you're able to work up the best possible sweat in the least amount of time.
- Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and better experience than any other sauna.
- Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
- Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.
Finnmark makes these to fit the FD-2. All sold separately.

Does the FD-2 need special wiring?
No. It runs on a 120V 15 A circuit — an ordinary household supply. That is the main practical advantage of an infrared cabin over a traditional sauna heater, which normally needs a 240V hardwired circuit.
How hot does the FD-2 get?
170° F. Finnmark states it reaches that in under an hour on a standard outlet. Infrared warms the body directly rather than heating the air, so it works at a lower air temperature than a traditional sauna.
Will the FD-2 fit through my doorway?
It ships flat as panels rather than assembled, so the doorway is rarely the problem — the largest single panel is what matters, not the 44" (111.7 cm) × 48" (121.9 cm) assembled footprint. Measure your space against the exterior dimensions above.
