The stylish and elegant Quattro TW from Cozy Heat will complement the rustic appearance of your home sauna, and its through-the-wall design allows you to load firewood from outside your sauna. COZY has taken the ancient wisdom of building a sauna to a higher level. This unique wood-burning stove is hand-made in Estonia, where sauna bathing is part of daily 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 most sensitive part of the wood-burning heater, the flame cutter, is made of 5mm-thick stainless steel, making COZY heaters extremely durable. 

The Quattro TW's clean lines and minimalist design create an understated elegance, and the large viewing window allows you to view the mesmerizing glow of the dancing flames. Experience the timeless allure of a traditional wood-fired sauna and discover the true essence of relaxation with the Cozy Heat Quattro TW.
