Overview
The Finnmark FD-5 Trinity XL is the flagship of the Finnmark lineup — a 3-person, full-spectrum infrared and steam sauna combo that delivers the most complete home sauna experience available anywhere. Built on the same dual-modality Trinity platform as the FD-4, the XL adds a larger cabin, expanded heater array, and greater capacity for families, training groups, or wellness enthusiasts who want the ultimate home recovery environment. Switch between full-spectrum infrared (up to 170°F) and wet steam (up to 212°F) at the touch of a button.

How It Compares
The FD-5 Trinity XL is the largest and most capable sauna in the Finnmark lineup. Compared to the FD-4 Trinity, it adds a third seat, a larger cabin, and an expanded heater array for more even infrared distribution across all three positions. Compared to standalone 3-person infrared saunas, the Trinity XL adds a full steam generator — no other 3-person home sauna combines full-spectrum infrared and steam at this level. For buyers evaluating commercial-grade saunas vs. premium home units, the FD-5 delivers commercial performance at a fraction of the cost and footprint of a built-in steam room.
