Saunatonttu Heater

Heat Storing Heater: Ready When You Are

A collaboration between Finnleo and world-renowned designer Ristomatti Ratia, the Saunatonttu is the ultimate sauna heater. Incorporating several patented features and superb European design, Saunatonttu is truly the “best sauna heater in the world”, bar none. Its secret is in the constant heat retention by the large quantity of rocks within the super-insulated shell. This means soft, perfect heat is always available, letting you enjoy a sauna without preheating.
