FD-5 Trinity XL Infra-Steam Sauna
FD-5 Trinity XL Infra-Steam Sauna
Best for larger hybrid sauna setups: The FD-5 Trinity XL combines a four-person cabin, full-spectrum infrared, integrated red light, and a 4.5kW traditional Harvia heater in one home sauna system.
4-Person Home Sauna with Infrared & Traditional Heat, 72"W × 48"D × 83"H
The Finnmark FD-5 Trinity XL is built for buyers who want more space and the flexibility to choose between full-spectrum infrared heat and a traditional sauna experience. Its larger four-person cabin combines Finnmark Spectrum Plus™ infrared heaters, Spectrum Carbon 360° panels, integrated red light, and a Harvia KIP Series 4.5kW traditional heater.
Use the infrared system for lower-air-temperature sessions, or use the traditional heater and sauna stones for higher heat with the option to add water to the stones for steam. The FD-5 is the largest hybrid model in the Finnmark Trinity lineup and is designed for dedicated home wellness rooms, larger home gyms, and households that want room for multiple users.
