Finnmark FD-4 Trinity Infrared and Traditional 2-Person Hybrid Sauna

2-Person Home Sauna with Infrared & Traditional Heat – 48"W x 48"D x 78"H

The Trinity Combination Sauna is the only sauna available that combines Finnmark’s UL listed Spectrum Plus infrared heaters with a Harvia Vega 120V traditional heater, plus red light therapy.


Eco-Friendly and Efficient Design

No need to compromise. The Finnmark FD-4 Trinity Combination Sauna features UL listed infrared heaters together with a traditional sauna heater. Experience the combined benefits of infrared heat and traditional steam sauna rocks.


Contemporary Amenities for an Enhanced Sauna Experience

Get hot fast. The infrared heaters used in this system have passed rigorous Underwriter Laboratories testing and are used alongside a traditional sauna stove.

Short-wave far infrared heat penetrates muscles and joints, helping promote deep sweating and a more intense sauna experience compared to standard carbon panel heaters.

The Harvia Vega 1.9kW traditional heater allows you to pour water over hot stones for an authentic steam sauna experience.

Enjoy both intensity and relaxation only available in a true steam and infrared combination sauna.


Red Light Therapy Benefits

Red light therapy is a form of phototherapy using low-level wavelengths that penetrate the skin and support the production of collagen and other proteins, offering potential wellness benefits.

It is a powerful enhancement to your sauna wellness routine.
