Harvia Pro 20 SL Wood-Burning Sauna Stove

The Harvia Pro 20 SL is a powerful and versatile wood-burning sauna stove designed for medium-sized sauna rooms. It allows convenient heating from an adjacent room or even from outside the building—keeping the sauna clean, quiet, and free of wood debris.

Built with Harvia’s renowned craftsmanship, the Pro 20 SL features a large stone capacity (up to 88 lbs / 40 kg) and a durable 10 mm fire chamber cover that ensures even, long-lasting heat. The cast-iron-framed glass door reveals the warm glow of the fire from the other side of the wall, adding both atmosphere and practicality.

Adjustable legs make installation easy and secure on uneven floors, while the reversible door hinge offers flexible setup options. The stove’s graphite black steel finish adds a modern look that complements any sauna design.

For added convenience, the Harvia Pro 20 SL can be paired with a chimney-mounted water tank (sold separately) to heat water while you enjoy your sauna.
