The Harvia M3SL is a compact wood-burning sauna stove with a through-the-wall firebox — perfect for heating your sauna from an adjacent room or outside. Ideal for small to medium-sized saunas.

It features a durable black steel body, a glass door for fire visibility, and a reversible door for flexible installation.

Note: Includes a 115mm (4.5") flue connection. A 6" (155mm) adapter is required for North American installation and must be purchased separately.
