Heats your sauna while serving as a fireplace in the next room.

The Harvia Legend 300 Duo is a powerful 2-in-1 wood-burning sauna stove and fireplace heater, designed for those who value both performance and ambiance. With its through-the-wall firebox, you can heat your sauna from an adjoining room or outside the building—while enjoying the warm glow of a real fire on the other side.

Built with Harvia’s signature black steel frame that holds an impressive 573 lbs (260 kg) of stones, the Legend 300 Duo provides a soft, even heat and abundant steam, even after the fire has faded. Its open-frame structure allows optimal airflow around the stones, ensuring steady warmth and long-lasting comfort.

The fire chamber features Harvia’s advanced grate design, which separates combustion air for cleaner, more efficient burning—enhancing both heating performance and stove durability. Compact safety distances allow for flexible bench placement, while adjustable legs make installation simple and secure. The reversible door adds even more versatility for various sauna layouts.

For added functionality, the Legend 300 Duo can be paired with a chimney-mounted water tank (sold separately), allowing you to heat water as you enjoy your sauna.
