The Harvia Legend 240 SL Wood-Burning Sauna Stove brings authentic Finnish sauna tradition to your home with a powerful, efficient design. Its black steel frame holds an impressive number of stones, delivering rich, consistent heat even at lower temperatures. The large stone capacity ensures long-lasting warmth—perfect for extended sauna sessions.

Engineered with a modern grate structure, the Legend 240 SL separates combustion air for cleaner, more efficient burning and extended stove life. Adjustable legs make installation easy, and reduced safety distances provide flexible bench placement.

This model features a through-the-wall fire chamber, allowing you to heat the sauna conveniently from an adjacent room or exterior space. The reversible door adds flexibility for any layout, while optional accessories like the pipe-mounted water heater further enhance your setup.

Durable, efficient, and visually striking, the Harvia Legend 249 SL is built to provide a traditional wood-fired sauna experience with modern performance and reliability.
