Hand-made in Estonia, where sauna bathing is a national tradition, Cozy Heat has taken the time-honored craft of building sauna stoves to a higher level with its SW wood-fired sauna stove.
The Cozy SW features an appealing sleek and contemporary cylindrical shape. Its smooth curves create a sense of elegance and style while contributing to efficient heat distribution. This design ensures that the sauna reaches and maintains your desired temperature. The part of the wood-burning heater that must be the strongest, the flame cutter, is made of sturdy, 5mm-thick stainless steel making COZY heaters extremely durable.
Perfect for mild, long-lasting heat, the Cozy Heat SW wood-burning sauna stove is perfect for pouring a ladle of water over hot stones for an intense, luxurious steam and a more gratifying sauna experience.
