Otra shares a common design with the Akko masonry heater. The narrower Otra fireplace is equipped with a high, vertically oriented door. The protruding decorative trim and rounded corners at the top and base lend a feeling of old-world elegance and atmosphere. The placement of the tiles has been designed so that decorative trim can be placed on the tile rows running on both sides of the door by using surfaces that have been treated in different ways, such as the naturally cut or water-cut soapstone. The efficiently heat-retaining fireplace is available in three heights.
