Harvia Legend 300 Duo: a two room wood stove and fireplace for saunas up to 1,059 cubic feet
The Harvia Legend 300 Duo is the largest Legend wood-burning stove, built to sit in a wall between two rooms. Its stone-filled steel frame heats the sauna, while the extended firebox faces the next room as a fireplace, with a wide glass door set in a brushed stainless frame. Rated at 23.5 kW, it suits saunas from 529 to 1,059 cubic feet and holds 572 pounds of stones for heat that lingers long after the last log. It measures 23.6 inches wide, 30.7 inches deep, and 40.9 inches tall and weighs 214 pounds before stones. The door opens from either side, the legs adjust, and the flue exits from the back or the top.
The box holds the steel frame, stove body, door, firebox extension, wall flange, ash box, and manual. Sauna stones are sold separately, so add the 13 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 smoke pipe cover, a floor plate, a pipe-mounted water tank, and a wood safety rail are optional. Smaller sauna? The Harvia Legend 240 Duo stove covers 353 to 848 cubic feet. The Harvia Legend 300 Duo ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
How does the stove and fireplace combo work?
The Legend 300 Duo is designed to be heated from outside the sauna or from an adjoining room, so one fire serves two rooms: a sauna stove on one side and a fireplace on the other. The included flange and fire chamber extension support the through-wall installation, and the installation manual on this page walks through the exact setup.
What size sauna can it handle?
This stove is rated 23.5kW and suits sauna rooms from 529 to 1059 cubic feet. The abundant stone mass held in its black steel frame keeps giving off good heat even when the fire dies down, which helps a larger room stay evenly warm between firings.
How many stones does it take, and are they included?
This heater requires a minimum of 572 lbs of stones, which is 13 boxes. They are supplied through the Required Stones selector on this page, so add the 13 boxes to your order. Harvia recommends one extra box so you can hand-pick stones for the best fit, form, and function.
Is the chimney included?
No. Chimney and assembly kits, chimney extensions, smoke pipes, and a 4.5-inch Euro to 6-inch USA pipe adapter are all available as add-ons on this page. The stove has both upper and rear connection openings plus a soot opening for cleaning; run the chimney per the installation manual and your local codes.
What is included in the box?
The delivery includes the steel frame, stove body, stove door, ash box, flange, fire chamber extension, and the installation and operation manual, covered by a 2-year warranty. Sauna stones and chimney components are chosen through the add-on selectors when you place your order, along with options like the Legend series safety railing and protective sheath.
How heavy is the Legend 300 Duo?
The heater itself weighs 214 lbs, and the full shipment with sauna stones comes to about 830 lbs. Because of that weight it ships on a wooden pallet by special-appointment freight with curbside delivery only, and the store contacts you before shipping to arrange the details.
Can the stove door be repositioned?
Yes, the direction of the door opening can be changed, and the adjustable legs make the stove easier to level and place. For protection around the stove, the WL200 protective sheath panel, protective bedding, and the SASPO240 safety railing are listed in the recommended add-ons on this page.
