COZY has taken the craft of building a wood-fired sauna stove to the next level. This Cozy Heat though-the-wall wood-burning sauna stove is hand-made in Estonia - where sauna is a way of life - and is perfect for intimate sauna spaces. 

Wood-burning saunas are best for mild and long-lasting heat, designed for pouring water over hot stones to create the perfect amount of steam. Its through-the-wall design allows you to feed firewood into the stove from outside your sauna room.

The most sensitive part of the wood-burning heater, the flame cutter, is made of 5mm-thick stainless steel making COZY heaters extremely durable.
