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

The Best of Both Worlds — Infrared Meets Traditional

The Finnmark FD-4 Trinity Hybrid Sauna combines the deep-penetrating warmth of full spectrum infrared with the classic heat of a traditional sauna heater. Perfect for 2 people, this hybrid design gives you the freedom to switch between therapies or blend both for a custom sauna experience — all in the comfort of your home.

Why Choose the Finnmark FD-4 Sauna?

Dual Heating Technology

Unlike standard saunas, the FD-4 offers both:

• Full Spectrum Infrared — UL-listed Spectrum Plus™ short-wave + Spectrum Carbon 360° long-wave panels for fast heat-up, deep muscle penetration, and low EMF performance.

• Traditional Sauna Heater — Authentic Finnish-style heating for a classic, high-heat sweat experience with steam capability.

Compact 2-Person Design

The FD-4 is crafted for couples or individuals who want spacious comfort without taking up too much room. Its smart footprint allows it to fit seamlessly into homes, gyms, and wellness studios.
