Finnmark FD-5 Trinity XL Infrared and Steam Sauna Combo, 4 Person
Product Description
The Finnmark FD-5 Trinity XL puts two kinds of heat in one cabin. Sit under the infrared panels for a lower, dry warmth, or load the Harvia stove and ladle water over the stones for steam. It is the largest room in Finnmark's Trinity line, a four-person cabin finished in clear Western Red Cedar.
The FD-5 is a freestanding cabin that stands on any level, load-rated floor indoors. A Thermal Plus Canadian Aspen shell wraps the cedar interior, a two-tier bench seats four, and an 8mm tempered glass front opens the room. A 5-inch LCD touchscreen with Bluetooth audio, 6-inch marine-grade speakers, and multi-color LED lighting sit inside.
Per Finnmark Designs, the traditional Harvia KIP stove reaches up to 190 degrees Fahrenheit and the full-spectrum infrared side up to 170, with the infrared drawing 2.7 kW on a dedicated 240-volt circuit and the 4.5 kW stove on its own. The infrared comes from Spectrum Plus short-wave panels paired with Spectrum Carbon panels, and the stove ships with one box of sauna stones. It runs on dedicated 240V circuits; have a licensed electrician confirm the connections before installation.
We confirm your exact shipping timeline within 1-2 business days of your order - or email us before you buy for the current lead time on this product. Your order ships with free standard shipping to the lower 48. The FD-5 carries a limited warranty from Finnmark Designs, with a 2-year warranty on the Harvia stove.
