Overview

The Finnmark FD-5 Trinity is a premium 3-in-1 hybrid sauna that combines full-spectrum infrared heat, a traditional 4.5 kW sauna heater with vulcanite stones, and integrated red light therapy into one advanced home wellness system.

Designed for homeowners who want both modern infrared performance and authentic Finnish steam, the FD-5 Trinity allows you to choose your preferred heat experience — or combine them. The UL-listed Spectrum Plus™ infrared heaters deliver short-wave infrared heat designed for fast warm-up and deep, penetrating warmth, while the traditional heater enables water to be poured over heated stones for a classic steam (löyly) sauna experience.

Integrated medical-grade red light therapy adds another dimension to your wellness routine, supporting recovery-focused sessions and enhancing the overall sauna environment.

Unlike standard infrared-only saunas, the FD-5 Trinity offers the versatility of hybrid operation while running on standard residential electrical connections. This makes it a practical solution for homeowners seeking the benefits of infrared, steam, and light therapy in a single, space-efficient design.

For those looking for a hybrid infrared and traditional sauna with red light therapy in one unified system, the Finnmark FD-5 Trinity delivers a powerful, flexible, and premium home sauna experience.
