Cozy Heat elevates traditional sauna stove design with the OG 12kW Wood-Burning Sauna Stove, engineered for durability, performance, and refined aesthetics. One of the most critical components—the flame cutter—is constructed from 5 mm-thick stainless steel to support long-term, high-temperature use.

Handcrafted in Estonia, where sauna bathing is a way of life, the Cozy Heat OG 12kW Wood-Burning Sauna Stove delivers steady, long-lasting heat and is designed for pouring water over heated stones to create smooth, consistent steam. Its contemporary trilateral design features clean lines and subtle curves, making it a functional centerpiece that complements both traditional and modern sauna interiors.

Important: Sauna stones are required for operation and are sold separately. This stove requires 6 boxes of sauna stones.

Cozy Heat OG 12 is ideal for small to medium sauna rooms (210–423 cu. ft.).
