Finnmark FD-5 Trinity XL Infrared & Steam Sauna Combo

The Finnmark Designs TRINITY-4X6 (FD-5) is the most advanced hybrid home sauna on the market. This 3-in-1 wellness solution combines full-spectrum infrared, a powerful traditional steam heater, and red light therapy into one meticulously engineered sanctuary.

Unlike other combination saunas that use lower-grade panels, the Trinity features UL-listed Spectrum Plus™ short-wave infrared heaters, offering deeper tissue penetration and hotter temperatures—up to 170°F infrared and 190°F traditional—all in under an hour. Add in the Harvia KIP Series 4.5kW electric sauna heater, and you're stepping into a true Finnish-style steam experience. Splash water on the rocks, breathe deep, and let the heat do the healing.

But it doesn’t stop there. The integrated medical-grade Spectrum Red Light™ panel enhances skin health, circulation, and recovery. Encased in Thermal Plus™ Aspen wood and lined with antimicrobial Western Canadian cedar, the Trinity is built for longevity and purity. This is more than a sauna—it’s the cornerstone of a life well lived.
