COZY has taken the ancient craft of building a sauna to a higher level. The part of a wood-burning heater that must be the strongest, the flame cutter, is made of sturdy, 5mm-thick stainless steel making COZY heaters extremely durable.

The Cozy Heat O wood-burning sauna stoves are perfect for mild and long-lasting heat, designed for pouring water over hot stones to create intense and luxurious steam for a more gratifying sauna experience.
