Finnmark FD-4 Trinity Infrared & Steam Sauna Combo (2 person Hybrid)
Description
Experience the best of both worlds with the Finnmark FD-4 Trinity Infrared & Steam Sauna Combo — a revolutionary 3-in-1 hybrid sauna that combines the benefits of full-spectrum infrared, traditional Finnish steam heat, and medical-grade red light therapy into one luxurious system.
With the Trinity 3-IN-ONE, you’ll enjoy full-spectrum infrared therapy that reaches up to 170°F, powered by UL-Listed Spectrum Plus™ heaters for deep muscle penetration and detoxification. At the same time, you can immerse yourself in the authentic steam experience of the Harvia Vega traditional heater, which delivers a Finnish-style sauna that relaxes muscles, improves circulation, and cleanses the skin through powerful, soothing steam.
Add to that the rejuvenating power of Spectrum Red Light™ Therapy, designed to stimulate collagen production, enhance skin tone, and promote healing — all while you relax in comfort.
The FD-4 Trinity Sauna is constructed with Western Canadian Red Cedar on the inside and Thermal Plus™ Aspen on the outside — both naturally antimicrobial, moisture-resistant, and built for decades of home wellness. No compromise, no shortcuts — just the complete sauna experience designed for the modern wellness lifestyle.
