Finnmark FD-3 Full Spectrum Infrared Sauna | 3–4 Person Indoor Cedar Sauna
A Spacious Full Spectrum Infrared Sauna Built for Home Wellness
The Finnmark FD-3 brings a premium infrared sauna experience into the home with a spacious cabin designed for 3–4 people. Crafted with a Canadian Grade “A” Clear Western Cedar interior and a durable Thermal Plus™ European Aspen exterior, the FD-3 is built for customers who want a larger indoor sauna with full-spectrum infrared heat, integrated controls, Bluetooth audio, and ETL safety certification.
The FD-3 features Carbon + Spectrum™ full-spectrum infrared heating — combining Spectrum Plus™ mid and far infrared heaters with Carbon 360° flat panel heaters for full-cabin infrared coverage. Reach up to 170°F in less than one hour on a standard 240V outlet.
Unlike traditional saunas, the FD-3 requires no stones, no water, and no plumbing. The full-spectrum infrared system delivers near, mid, and far infrared heat in a lower ambient temperature environment.
