Full-Spectrum Infrared Heating

The FD-4 Trinity incorporates Finnmark's Spectrum Plus™ infrared heating technology, providing an alternative heating experience to traditional high-temperature sauna bathing.

Infrared heating allows users to enjoy radiant warmth in a controlled indoor environment.

The integrated heating system gives the Trinity additional versatility for users who appreciate different sauna experiences.

Traditional Finnish-Style Sauna & Steam

For those who prefer the classic sauna experience, the FD-4 Trinity includes a built-in 1.9kW traditional sauna heater.

When operated according to the manufacturer's instructions, water can be applied to properly heated sauna rocks to create steam and adjust the humidity within the cabin.

This feature allows users to enjoy the distinctive warmth and atmosphere associated with traditional Finnish-style sauna bathing.

Integrated Spectrum Red Light™ Technology

The Trinity incorporates a 192-diode Spectrum Red Light™ panel as an additional feature within the sauna environment.

This integrated lighting technology offers users another way to personalize their sauna routine without requiring a separate standalone red light device.

The red light system is presented as a wellness feature and is not intended to diagnose, treat, cure, or prevent medical conditions.

Together, these materials contribute to a refined sauna environment designed for everyday enjoyment.

Designed for Personal Wellness
