The Ultimate Home Wellness Sanctuary

The Finnmark FD-5 Trinity XL is an industry-leading hybrid sauna that merges three distinct therapies into one spacious 4-person cabin. Whether you want the deep detox of infrared, the intense 190°F heat of a Finnish sauna, or the skin-rejuvenating benefits of red light, the Trinity XL delivers it all without compromise.

The Power of 3 Therapies in One

1. Full-Spectrum Infrared (Spectrum Plus™ & Carbon)
A combination of Spectrum Plus™ Short-Wave heaters and Spectrum Carbon 360° Long-Wave panels. The UL-listed short-wave heaters penetrate deep into muscles (25x deeper than standard carbon) for pain relief, while the large carbon panels surround the cabin to efficiently raise core body temperature for a profound, healthy sweat.

2. Traditional Steam Sauna (Harvia KIP 4.5kW)
Includes a robust Harvia KIP 4.5kW stainless steel heater. Splash water on the 50 lbs of included vulcanite stones to create authentic steam (löyly), creating varying humidity levels and high temperatures up to 190°F.

3. Medical-Grade Red Light Therapy
A dedicated Spectrum Red Light™ panel utilizes 192 medical-grade LEDs to produce therapeutic 650nm red light. This supports collagen production, reduces inflammation, and improves skin tone while offering full-color chromotherapy for mood enhancement.
