Harvia M3 16.5kW Wood-Burning Sauna Stove Kit | Complete Package with Olivine Diabase Stones, Chimney Kit & Protective Sheath — Silver or Black

The Authentic Wood-Burning Sauna Experience, Complete Right Out of the Box

The Harvia M3 16.5kW Wood-Burning Sauna Stove Kit is a fully equipped, professional-grade sauna heating solution built for spaces between 212 and 459 cubic feet. Designed and engineered by Harvia — one of the most trusted names in sauna manufacturing — the M3 delivers the kind of deep, radiant heat and crackling ambiance that electric heaters simply cannot replicate.

Everything Included. Nothing Left to Source. This all-in-one kit eliminates the hassle of compatibility guesswork. Every component needed for a complete installation arrives together, including the M3 heater, olivine diabase stones, protective bedding, chimney kit with extension, and protective sheath — ready to install from day one.

Powerful, Consistent Heat Output At 16.5kW, the M3 delivers steady, even heat throughout your sauna room. The wood-burning design creates a natural convective heat flow that warms the room thoroughly and maintains optimal temperature throughout your entire session.

Superior Stone Performance The included olivine diabase stones (4"–6") are specifically chosen for their exceptional heat retention and thermal stability — outperforming standard sauna stones in both longevity and consistent heat release. Löyly (steam) performance is notably smooth and sustained.

Durable Construction, Compact Footprint Built from high-grade stainless steel in your choice of silver or black, the M3 is engineered to withstand sustained high-temperature exposure without warping or degrading. At just 97 lbs with a compact 15"W x 18"D x 28"H profile, it fits comfortably into most sauna layouts without dominating the room.
