Finnmark FD-3 Full-Spectrum Infrared Sauna (4-Person)

Bring the luxury of a high-end wellness spa home with the Finnmark FD-3 Full-Spectrum Infrared Sauna, designed for up to four people. Spacious, elegant, and engineered with unmatched precision, this model delivers the most advanced infrared experience available.

The FD-3 is powered by Finnmark’s exclusive combination of UL-Listed Spectrum Plus™ short-wave and Spectrum Carbon 360° long-wave infrared panels. Together, they provide faster heating, deeper muscle penetration, and total-body infrared coverage that no single-technology sauna can match.

Built for both beauty and durability, the FD-3’s Western Canadian cedar interior naturally resists mold, bacteria, and odors, while its Thermal Plus™ Aspen exterior remains pristine for years—never warping or decaying. Reaching up to 170°F in under one hour, this sauna transforms daily self-care into a restorative, full-spectrum therapy session.
