Questions? We’re a small team and happy to help. Just reach out. There’s nothing like a traditional Finnish sauna, but this is as close as it gets with infrared. The Finnmark FD-3 reaches 170°F, the highest IR cabin temperature in the industry, plugging into a standard 240V outlet (NEMA 6-15P). How do they pull this off? It starts with walls insulated up to 4” thick using mineral wool and a radiant barrier. Western red cedar lines the interior. Thermo-Aspen clads the exterior. You won’t find this level of construction in cheaper kits. The FD-3 is the only 3-4 person infrared room that combines long-wave Carbon 360° panels with UL-listed short-wave Spectrum Plus™ heaters for true full-spectrum coverage. Each heater is strategically placed for full body coverage, deeper penetration, and the best infrared experience available. Backed by a 10-year warranty with all parts stocked in North America.
