Cozy Heat Sauna Stove

Made in Estonia, where sauna is a way of life, for smaller saunas. Wood-fired sauna stoves are ideal for gentle, long-lasting heat, and are designed for pouring water over the hot stones for a wonderful, steamy sauna.

COZY has taken the ancient craft of wood-burning sauna stoves to a completely new level and has created a unique wood-burning sauna stove hand-made in Estonia, where sauna bathing is a way of life.

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

Enjoy the satisfying experience that only a traditional wood-fired sauna heater provides.
