The Finnmark FD-4 Trinity is a premium 2-person infrared and steam sauna combo that brings three powerful wellness modalities into one elegant home cabin. Combining UL-listed Spectrum Plus™ infrared heaters, an authentic Harvia Vega Compact 1900 Finnish steam heater, and Spectrum Red Light™ therapy panels, the FD-4 Trinity delivers a truly versatile sauna experience unlike any other. Built with a naturally antimicrobial Western Red Cedar interior and durable Thermo-Aspen exterior, this ETL-certified, low EMF sauna reaches up to 170°F (infrared) or 190°F (steam), all on a standard 120V home outlet.

The spacious 48"W x 48"D x 83"H cabin features extra-large two-tier benches comfortably accommodating two people, while double-walled construction ensures efficient heat retention. The built-in LCD Wi-Fi touchscreen, Bluetooth audio, and 6" Hi-Fi speakers bring modern convenience to every session.
