Finnmark FD-5 Trinity XL Combination Sauna
A spacious 3-4 person home sauna combining full-spectrum infrared heat, a traditional 4.5 kW Harvia sauna heater, and integrated red light therapy in one premium cedar and aspen cabin.
The Finnmark FD-5 Trinity XL Infrared and Steam Sauna Combo is designed for homeowners who want a larger all-in-one sauna experience. It combines Finnmark’s Spectrum Plus™ infrared heating, a Harvia KIP 4.5 kW traditional sauna heater, and a 192-diode 650 nm red light panel inside a spacious cabin with two-tier seating.
Western Canadian Cedar lines the interior, while Thermal Plus™ Aspen forms the exterior. A Wi-Fi touchscreen, Bluetooth audio, tempered glass, and integrated lighting make the FD-5 a strong fit for premium home gyms, recovery rooms, finished basements, and dedicated wellness spaces.
