COZY elevates the traditional craft of sauna stove building with thoughtful engineering and durable construction. One of the most heat-exposed components—the flame cutter—is made from 5 mm-thick stainless steel, giving COZY wood-burning heaters exceptional strength and longevity.

Handcrafted in Estonia, where sauna bathing is deeply rooted in national culture, the Cozy Heat O 12kW Wood-Burning Sauna Stove is designed to deliver mild, long-lasting heat. It allows water to be poured over hot stones to produce rich, satisfying steam throughout your session.

At the core of the Cozy Heat 12 O is its distinctive circular rim design, which enhances visual appeal while promoting efficient, even heat distribution across the sauna room.

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

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