Description
Thanks to its clean, compact design, the UTU wood‑burning sauna heater fits easily into saunas of various sizes. Made from durable black steel and fully cladded for a modern appearance, the UTU combines rugged construction with a sleek, contemporary aesthetic.The door of the stove can be modified to open either on the left-or right-hand side, giving more options for the placement of this heater.
Correct amount of stones to be purchased separately.
We recommend 60kg (10-15 cm) of either olivine diabase or vulcanite sauna stones.
