The Ultimate 3-in-1 Sauna for Maximum Wellness
Why settle for just one type of sauna when you can have all three? The Finnmark FD-5 Trinity XL Infrared & Steam Sauna Combo is the largest and most advanced home sauna available, offering infrared therapy, a Finnish steam sauna, and medical-grade red light therapy—all in one beautifully crafted unit.
Whether you want the deep-penetrating detox of infrared, the intense heat and steam of a traditional sauna, or the skin-rejuvenating benefits of red light therapy, this sauna delivers it all.
Designed for up to four people, the Trinity XL is engineered for performance and luxury, with Finnmark’s UL-listed Spectrum Plus™ infrared heaters, a powerful Harvia KIP 4.5kW traditional sauna heater, and medical-grade Spectrum Red Light™ Therapy.
Built with premium Western Canadian cedar and Thermal Plus™ Aspen, this sauna is naturally antimicrobial, warp-resistant, and designed to last a lifetime.
