Finnmark FD-5 Trinity XL Infra-Steam Sauna
4-Person Home Sauna with Infrared & Traditional Heat
Dimensions: 72"W × 48"D × 78"H
The Finnmark FD-5 Trinity Combination Sauna is the most advanced home sauna available—combining true UL-listed Spectrum Plus™ infrared heaters, a traditional stone sauna heater with steam, and medical-grade red light therapy into one uncompromising wellness system.
This is the only sauna that delivers authentic infrared heat, traditional Finnish steam, and red light therapy together in one beautifully engineered design.
Overview – Why Trinity Is Different
Unlike basic “combo” saunas, the FD-5 Trinity uses real UL-listed infrared heater panels combined with a 4.5kW traditional sauna heater and vulcanite sauna stones, allowing you to splash water onto hot rocks for a true steam sauna experience.
- Infrared + Traditional Sauna + Red Light Therapy in one unit
- UL-listed infrared heaters (not carbon film panels)
- Traditional rocks and steam for authentic Finnish sauna sessions
- Fast heat-up with deep muscle penetration
Infrared, Steam & Red Light Therapy
- Spectrum Plus™ UL-listed short-wave infrared heaters — penetrate muscles and joints and make you sweat up to 25× more than standard carbon panels
- Traditional 4.5kW sauna heater — splash water onto stones for a luxurious steam sauna
- Spectrum Red Light™ Therapy — 192-diode medical-grade LED panel emitting 650nm red light with chromotherapy
Red light therapy supports collagen production, circulation, recovery, and skin health—making it a powerful enhancement to your sauna ritual.
