Helo and renowned designer, Ristomatti Ratia, created the ultimate sauna stove – the Helo Saunatonttu. Incorporating several patented features and superb European design, Saunatonttu is truly the “Best sauna stove in the world”, bar none. The secret of Saunatonttu is in the constant heat retained by the large quantity of stones (ca. 220 lbs) within the super-insulated stove. The stove creates soft, rich and moist steam. Small safety distances make Saunatonttu flexible in interior design.
