Finnmark
We sell Finnish saunas for a living, and Finnmark is the infrared brand we stand behind. The FD-1, FD-2 and FD-3 pair UL-listed Spectrum Plus short-wave heaters with Spectrum Carbon 360 long-wave panels and are rated to 170°F, and the FD-2 gets there in under an hour on a 120V outlet. Spectrum Plus is a sheathed element behind a reflector rather than a carbon panel, which is why it works in the Trinity models beside a rock heater making steam.
We carry seven FD models, and they go out right across the US and into Canada. The FD-4 Trinity, part FD-KN004, moves the most: a 1.9 kW Harvia rock heater and the panels in one 86 cubic foot room. Indoor walls are western red cedar over mineral wool and a radiant barrier up to four inches thick, and the FD-6 and FD-7 barrels put the same 1,750 watt Spectrum Plus panels outside. Freight to the lower 48 is free, and we size the room with you at (844) 565-1113.
Finnmark questions
Does a Finnmark sauna need a 240V circuit?
The FD-1 at 1,500 watts and the FD-2 at 1,750 watts both run on a standard 120V 15-amp outlet. The FD-3 draws 3,150 watts and takes a 240V 15-amp outlet on a NEMA 6-15P plug. The FD-4 needs two circuits: the infrared plugs into 120V, and the Harvia heater is hardwired at 120V and 15.9 amps or 240V and 8.
What is the difference between the FD-4 Trinity and the FD-5 Trinity XL?
The FD-4 is a 2-person cabin of 86 cubic feet with a 1.9 kW Harvia Vega Compact, which Harvia rates for 70 to 106 cubic feet and stacks with at least 29 pounds of stones. The FD-5 Trinity XL seats four at 130 cubic feet on a 4.5 kW KIP rated for 100 to 210, minimum 50 pounds of stones.
How much floor space does a Finnmark cabin need?
Exterior footprints are 38 by 38 inches for the FD-1, 48 by 44 for the FD-2, 72 by 46 for the FD-3, 48 by 48 for the FD-4 and 72 by 48 for the FD-5 Trinity XL. The FD-1, FD-2 and FD-3 stand 78 inches tall. The FD-2 weighs 393 pounds once it is built.
How long is the wait on a Finnmark sauna?
When a model is between shipments the wait has run about three months, and that lead time is the same at every authorized dealer. These ship LTL, and the carrier calls you to book a delivery appointment. Call (844) 565-1113 for the current timeline before you order.
