Finnmark FD-4 Trinity Combination Sauna (Infrared + Traditional + Red Light Therapy)

Experience the best of all worlds with the Finnmark FD-4 Trinity — the only combination sauna that blends full-spectrum infrared, traditional steam heat, and true red light therapy in one elegant design.

Powered entirely by standard 120V outlets, the Trinity combines UL-listed Spectrum Plus™ infrared heaters, a Harvia Vega 1.9 kW traditional heater, and medical-grade red light panels for a complete wellness experience. No electrician required — just plug in, heat up, and relax.

Enjoy deep infrared heat that penetrates muscles and joints, complemented by the soothing steam of the Harvia Vega heater for the ultimate detox and recovery session. The short-wave far-infrared technology produces up to 25 × more sweat than standard carbon heaters, while the Vega rocks let you pour water for an authentic steam sauna effect.

Enhance every session with red light therapy, proven to stimulate collagen production, support cellular recovery, and elevate mood. The FD-4 Trinity delivers the full spectrum of heat, light, and rejuvenation — redefining what a home sauna can be.
