Handcrafted in Estonia—where sauna culture runs deep—the Cozy Heat 18kW Thru-Wall Wood-Burning Sauna Stove is designed for compact sauna spaces and dependable performance.
Wood-fired sauna stoves are valued for their mild, long-lasting heat and the ability to pour water over hot stones to generate smooth, satisfying steam. The Cozy 18 TW model features a practical through-the-wall design, allowing firewood to be loaded from outside the sauna for a cleaner and more convenient setup.
Built for durability, the flame cutter—one of the most heat-exposed components—is made from 5 mm-thick stainless steel to withstand repeated high-temperature use. With its robust construction and thoughtful design, the Cozy 18 TW delivers a classic wood-fired sauna experience with reliable heat and timeless appeal.
