The Ultimate Infrared & Steam Sauna Experience—No Compromises
Why choose between an infrared sauna and a traditional steam sauna when you can have both? The Finnmark FD-4 Trinity Infrared & Steam Sauna Combo is the only sauna on the market that seamlessly combines UL-listed infrared heaters, a traditional 120V sauna heater, and medical-grade Spectrum Red Light™ Therapy—all in one luxurious and compact 2-person unit.
Experience the deep, detoxifying heat of infrared therapy, the intense sweat of a Finnish steam sauna, and the rejuvenating effects of red light therapy, all while using standard 120V power—no electrician required.
Whether you’re looking for muscle recovery, detoxification, or pure relaxation, this sauna delivers every wellness benefit possible in one powerful system.
