Harvia M3 SL Wood-Burning Sauna Stove

The Harvia M3 SL is designed for those who want the convenience of heating their sauna from an adjacent room or from outside the building. With its through-the-wall firebox design, you can load firewood without stepping inside the sauna, keeping the bathing area cleaner and more comfortable.

Compact and efficient, the M3 SL is ideal for small to medium-sized saunas. Its glass door lets you enjoy the natural glow of the fire, enhancing the sauna atmosphere, while the door’s opening direction can be reversed to suit your layout. For added convenience, this model can also be paired with a pipe-mounted water heater to heat water while you enjoy your sauna.

Like all Harvia stoves, the M3 SL is built with durability and user-friendliness in mind. Adjustable legs (available on the 20-series) help ensure stable installation, even on uneven floors, making setup simple and reliable.
