COZY has taken the ancient craft of building a sauna to a higher level. The part of a wood-burning heater that must be the strongest, the flame cutter, is made of sturdy, 5mm-thick stainless steel making COZY heaters extremely durable.
This unique wood-fired sauna stove is hand-made in Estonia, where sauna bathing is ingrained in the national culture.
The Cozy Heat O wood-burning sauna stoves are perfect for mild and long-lasting heat, designed for pouring water over hot stones to create intense and luxurious steam for a more gratifying sauna experience. At the heart of the Cozy Heat O is its innovative circular rim design, which not only enhances the heater's aesthetic appeal, but also ensures efficient heat distribution throughout your sauna space.
