Harvia Pro 20: a 24 kW wood sauna stove for rooms from 283 to 706 cubic feet
The Harvia Pro 20 is a graphite black, wood-burning steel sauna stove made in Finland for a medium-sized room, rated at 24 kW for saunas from 283 to 706 cubic feet. It measures 17 inches wide, 20 inches deep, and 30 inches tall, weighs 127 pounds, and has adjustable legs to keep it level. A large stone chamber holds 88 pounds of stones for full, lasting steam. The fire glows behind a glass door set in a cast iron frame.
The box comes with the stove, its door, an ash box, the legs, and the manual. Sauna stones are sold separately, so add the 2 boxes it needs on the page. A chimney is not included, so pick the chimney kit, any extensions, and the adapter to 6 inch US pipe on the page. A protective sheath, a floor plate, a pipe-mounted water tank, and a bucket and ladle set are optional. Want it all in one order? The Harvia Pro 20 stove package includes the chimney, sheath, floor plate, water heater, and stones. The Harvia Pro 20 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What makes a wood-burning stove different from an electric sauna heater?
Wood-burning stoves bring the most authentic sauna experience: the room is heated by a real fire rather than electric elements, and here the flames glowing behind the cast-iron-framed glass door become part of the sauna’s atmosphere. This stove is designed for vigorous sauna bathing, with a large stone compartment that delivers pleasant, hearty steam. You can compare other wood-burning sauna stoves by size and style.
What size sauna is the Pro 20 designed for?
The Pro 20 is a 24kW stove rated for medium-sized sauna rooms from 283 to 706 cubic feet, with a minimum room height of 82.2 inches (2090mm). If your room sits near either end of that range, confirm fit and clearances in the installation manual linked on this page before ordering.
Do sauna stones come with the stove?
The stove requires a minimum of 88 lbs of stones, which is two boxes — select them with the Required Stones option on this page so they ship with your order. Since each natural stone is unique in shape and size, Harvia recommends adding an extra box so you can choose the highest quality stones for fit, form, and function (additional freight charges apply).
How is the stove vented?
The flue connects at either the back or the top of the stove. A chimney isn’t part of the standard package, but chimney and assembly kits, chimney extensions, smoke pipes, and a 4.5-inch-to-6-inch Euro-to-USA pipe adapter are all available as add-ons on this page. Plan the full chimney run according to the installation manual and your local building codes.
Can I pour water over the stones for steam?
Yes — the Pro 20’s large stone compartment is exactly why its steam is as pleasant and hearty as you can hope for. If you’d like a matching bucket and ladle for throwing water, a bamboo and aluminum sauna bucket set in black or white can be added to your order on this page.
What firewood does it take?
Use firewood up to 15 inches (390mm) long with a diameter of 3 to 5 inches (80-150mm) — that’s what the fire chamber is sized for. For loading and burning guidance, follow the installation and operation manual that comes with the stove; a copy is also linked in the Manual tab on this page.
What's in the box, and what's the warranty?
You get the sauna stove, adjustable legs, stove door, ash box, and the installation and operation manual, backed by a 2-year warranty for consumer use. The stove is steel construction in a graphite black finish, designed, engineered, and made in Finland. It’s a floor model, and the adjustable legs make it easier to set level during installation.
