FIN Series 4.5KW Sauna Heater
Finlandia FIN-45
Overview
The Finlandia FIN-45 electric sauna heater is engineered for saunas up to 210 cubic feet (CF). In the rich tradition of authentic Finnish saunas, the wall-mounted FIN-45 sauna heater generates a satisfying, penetrating heat. The 4.5-kilowatt FIN-45 includes professional-grade stainless-steel heating elements and stainless-steel components. The unit is designed so that the sauna rocks are in direct contact with the heating elements for improved efficiency. The FIN-45 sauna oven features triple-wall construction for greater safety and lower surface temperatures. Its exceptionally large rock capacity provides optimal heat storage. When you buy a sauna, quality and value are important. Finlandia sauna heaters are engineered to provide years of safe, reliable, and efficient operation. Finlandia sauna heating units are made by Harvia and imported from Finland, the home of sauna. The FIN-45 electric sauna stove creates a traditional sauna experience by blanketing the room with an intense heat. Finlandia FIN Series heaters are perfect for any home sauna kit. The Finlandia FIN-45 heater is available in 240V, single-phase (1PH) or 208V, three-phase (3PH) configurations. The unit may be ordered with the standard red finish or the optional stainless-steel exterior (FIN-45-S). The FIN-45 sauna heater requires a control for operation, sold separately. For 240V/1PH operation, the CX170 control or F1T control can be used. For 208V/3PH operation, the CX170 control or FT2 control with FX303 contactor can be used. For commercial applications, the FIN-45 can be run 24 hours a day with the CX170 control and 24H7D time clock, or the F2 control with its respective contactor and 24H7D time clock. The Digital control comes with a power supply. The manual F-2 and F-2T controls require a contactor. The FIN45 carries a limited lifetime warranty and is fully serviceable. All Finlandia and Harvia sauna heaters are UL and ETL listed and tested for your safety.

to a friend
We're not chasing fancy features and this delivers a proper hot, dry bake with a good burst of steam when you want it. Took a touch longer to arrive than the website estimated, but a quick note to support got us an honest update rather than a canned reply, so we didn't mind the wait.
Sized it for a 6x5 and it brings us to temperature in about thirty minutes flat. The dial is refreshingly simple — my husband refuses to learn anything with a screen. A rep named Marcus walked us through clearances over the phone before we bought, which saved us repositioning the bench. Freight was prompt and the driver helped us get it to the side gate.
Our old heater finally died and this dropped right into the same footprint. Heats more evenly than the one it replaced and the stones hold warmth long after shutoff. I appreciated that the rep didn't upsell me — he confirmed the FIN-45 was plenty for our space and left it there.
Bought this partly because it's built in Oregon, not shipped halfway around the planet, and the fit and finish prove the point. Welds are tidy, the guard is solid, nothing rattles. Showed up well-packed on a pallet with zero shipping rash. The order team even confirmed my voltage before processing so there'd be no surprises.
Flip the timer, wait half an hour, climb in. That's all there is to it, and I love it for that. Packaging was overkill in the best way, and a follow-up email checked that everything arrived intact. Small touch, but it told me they actually pay attention.
What strikes me is how silent it runs. No ticking, no fan, just clean radiant warmth climbing the walls. We've used it most nights since October and it hasn't skipped a beat. Communication was a bright spot too — I got a real tracking number and an actual human reply when I asked about rock arrangement.
For the money there's nothing on the market this well made. Thick stainless, generous stone capacity, and a heat that feels gentle on the lungs even up high on the top bench. Sauna Co. shipped same-week and texted me the delivery window so I wasn't stuck home all day guessing.
No complaints about the unit itself — sturdy, quiet, throws lovely steam off a ladle of water. Knock one star only because I needed an electrician for the 240v hookup and that wasn't obvious to me as a first-timer. To be fair, the Sauna Co. order confirmation did flag it, and when I emailed to double-check they replied within the hour with the amperage spelled out.
I wanted a plain, honest heater with no app and no nonsense, and the FIN-45 is exactly that. The stainless shell barely warms to the touch and the rock basket swallows more stones than I expected, so the heat comes soft and round instead of harsh. Sauna Co. answered my pre-order questions the same afternoon and the box showed up three days early, double-walled and dented-free.
