Wood Burning Sauna Heater Casares III Istan VII

The Casares III Istan VII combines the raw heating power of the Original series with the advanced steam properties of the Iivari line to deliver an unparalleled sauna experience. Featuring an expanded, open-mesh stone compartment that holds 75–85 kg of stones directly above the fire chamber, it heats up rapidly and allows you to pour water over both the top and sides for exceptionally soft, long-lasting steam. Any unevaporated water safely drains to a built-in bottom reservoir for gradual release, creating a perfectly humid, customizable löyly. Certified with the prestigious Finnish Avainlippu (Key Flag), every individual stove is custom-built from start to finish by a single artisan and arrives with a personalized nameplate showing its unique serial number and builder's name.
