The Cozy Heat Quattro Sauna Stove is a Cozy Heat wood-burning sauna stove, handmade in Estonia. Quattro is the wider, layered-stone presentation — same 12/18 kW choice, different look. Listings here offer 12 kW and 18 kW. Manufacturer ranges: 12 kW about 210–423 cu ft; 18 kW about 317–635 cu ft. Our older combined line of 210–635 cu ft covered both sizes on one page — pick kW from the option list, not from a blended number.
How it heats
Wood fire under a large stone pile. No electric heater circuit. Pour water for löyly. Standard: load from inside the sauna. Top flue. Follow the Cozy manual for clearances and chimney. First firing is smoky — do it as the manufacturer says.
What’s included
Stove in the finish/model named
Stones sold separately unless a package names them
