Infrared, steam and red light in one
The FD-4 Trinity puts three sessions in one cabin. UL Listed Spectrum Plus™ infrared heaters bring you to 170°F, a Harvia™ Vega traditional heater gives you hot rocks and steam, and a Spectrum Red Light™ panel adds 650nm red light therapy.
The interior is antimicrobial Western Canadian cedar and the exterior is Thermal Plus™ Aspen. An extra-large two-tier bench gives you room to lie back while the heat works.
Three sessions, one cabin
Finnmark describes the Trinity as the only combination sauna with true UL Listed infrared heaters alongside a Harvia traditional heater that produces high-heat steam. You get infrared warmth, traditional rocks with steam and a medical-grade red light therapy LED panel in the same session.
Heat that builds fast
Finnmark says these are the only heaters that have passed the tests Underwriters Laboratories requires for use alongside a traditional steam sauna stove. Short-wave far-infrared penetrates muscles and joints, and Finnmark rates it to make you sweat 25x more than typical carbon panel heaters. It calls them the best infrared heaters on the market.
Steam when you want it
Take your infrared session further with a Harvia™ traditional heater. Splash some water on the rocks and enjoy the steam. The wall-mounted, stainless steel Vega is designed, engineered and made in Finland.
Red light therapy, built in
A 192-diode medical-grade LED panel produces 650nm red light therapy, combined with chromotherapy for the days you need a little love.

Can I run the infrared and the Harvia heater together?
Yes. Finnmark says its Spectrum Plus™ heaters have passed the Underwriters Laboratories tests needed for use in combination with a traditional steam sauna stove, and the Trinity is built around that pairing.
Do I need to buy sauna stones?
The Harvia Vega needs at least 29 lbs of sauna stones (1 Box-AC3000). Each natural stone is unique in shape and size, so Finnmark recommends an extra box to choose the best stones for fit, form and function; additional freight charges apply. Keep the stones well maintained, since Harvia's warranty depends on it.
What electrical does it need?
Finnmark lists the traditional heater at 120V and 1.9kW. The spec sheet below covers the full cabin requirements, and any electrical work must be done by a licensed electrician.
Where do you ship, and can I talk it through first?
