You load wood, poke the fire and empty the ash from outside the sauna, and none of the bark, splinters or smoke ends up on the benches. The stone cage of angular diamond expanded mesh stays in the hot room where it belongs. The COZYTW12 heats a home sauna room of 210 to 423 cu ft and the COZYTW18 covers 317 to 635 cu ft.
