COZY has taken the craft of building a wood-fired sauna stove to a higher level. The SW-TW’s convenient through-the-wall design lets you feed the firebox from outside your sauna so you don’t need to bring wood into the room.

Cozy Heat’s SW-TW wood-burning sauna stoves are made in Estonia, where sauna bathing is a way of life. Designed for performance and durability and strength. 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 robust.

Wood-fired sauna stoves produce a mild and long-lasting heat and are designed for ladling water over hot stones to create the most satisfying steam sauna.
