The Harvia 20SL offers the convenience of through-the-wall heating, allowing you to heat your sauna from an adjacent room or from outside. This setup keeps firewood and ash out of the sauna, helping maintain a clean and relaxing environment. The reversible door makes it easy to adapt the stove to your sauna’s layout, offering flexible installation options.

Built with a durable black galvanized steel and stainless steel finish, the 20SL combines strength with a modern look. Its glass door lets the warm glow of the fire shine into the sauna, creating a cozy, inviting atmosphere. Ideal for small to medium-sized saunas, this stove can also be connected to a separate water tank for added functionality.

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