Cozy Heat SW Through-Wall Sauna Stove Package

Cozy has taken the craft of building a wood-fired sauna stove to a higher level. The through-wall design lets you feed the firebox from outside your sauna, so you don't need to bring wood into the room. Crafted in Estonia, where sauna bathing is an integral part of life, the Cozy SW TW is built for performance and durability. Its flame cutter, made from robust 5mm-thick stainless steel, delivers exceptional strength and long-lasting reliability. Wood-fired sauna stoves produce a mild, long-lasting heat, designed for ladling water over hot stones for a satisfying steam sauna.
