Most wood sauna stoves top out somewhere around 400 cubic feet. The PRO 26 is built for the rooms past that. It is a graphite black steel wood burning sauna stove made in Finland, part number WKPR26M, rated at 26.6 kW and covering rooms from 353 to 918 cubic feet. That is a commercial or club-sized room, or a large private sauna with high ceilings.
The PRO 26 carries 110 lbs of stone, which is less than the Legend or the Cilindro. That is deliberate. This stove is sized for air volume rather than for a long steam column, and it heats a big room quickly rather than storing heat for a long soak. The cast-iron glass hatch takes a 39 cm log, so you are not cutting firewood down to fit, and the 6 mm fire chamber cover is built for the duty cycle a commercial room asks of it.
Safety distances to combustible material are 14.76 inches at the front, at the rear and at each side, plus 50.4 inches from the top of the stove to the ceiling. Those side and rear figures are four times what the Linear 18 needs, so a room that suits a smaller Harvia may not take this one. Do not carry a clearance figure across from another model. The floor must be non-combustible with load-bearing capacity for a 143 lb stove plus 110 lbs of stone. A concrete slab of 60 mm or more takes it directly; anything else, including tile, needs the WX018, WL100 or WL110 protective bedding. No North American listing is published for this stove, which matters more on a commercial installation than a private one, so confirm what your authority and your insurer require.
BEST FOR
NOT IDEAL FOR
Harvia publishes the WL700 and WL750 sheaths for the PRO 26, and unlike the Legend it publishes the clearances that apply once one is fitted. They are worth reading carefully. With the sheath on, the sides and rear drop from 375 mm to 73 mm, which is the reason most people fit one. But the front distance goes the other way, from 375 mm up to 526 mm. So a sheath buys you width and depth and costs you room in front of the door. Plan the layout around that rather than assuming a sheath shrinks everything.

If your room is under 353 cubic feet, the Harvia Linear 18 Compact at 14.3 kW or the Harvia Legend 150 at 16 kW will suit it better and cost less to run. If you want the same output class with a water tank, ask us about the PRO 20 ES, LS and RS variants.
A 26.6 kW stove in a room that cannot give it 14.76 inches on every side is a fire risk, not a bargain. Send us your room dimensions, your wall and floor construction and your flue route, and we will tell you whether the PRO 26 fits or whether a smaller stove serves you better. We stock the sheath, the bedding and the stones alongside it. Call 866-861-6317, 9am to 6pm EST, Monday to Friday, or book a call. Financing is available at checkout. White glove delivery options available as a paid add-on.
14.76 inches to combustible material at the front, rear and each side, and 50.4 inches from the top of the stove to the ceiling. This is the most demanding stove in the Harvia range on clearance, so measure before you buy.
Yes on the sides and rear, which drop from 375 mm to 73 mm with the WL700 or WL750 fitted. But the front distance increases from 375 mm to 526 mm at the same time, so you gain depth and lose room in front of the door.
No. No North American listing is published for this stove and no CE or EAC mark is published for it either. It is tested to EN 15821:2010 through VTT in Finland. On a commercial installation this is worth confirming with your authority and your insurer before you order.
110 lbs of 10 to 15 cm split-face stone, which is three 44 lb boxes of Harvia AC3020. Stack loosely so air can move through, and stand elongated stones on end.
Not directly. Tile adhesive and grout are not heat-radiation resistant. A concrete slab of 60 mm or more takes the stove directly. Anything else needs the WX018, WL100 or WL110 protective bedding.
