## Description

### Cozy Heat SW Thru-Wall Sauna Stove: tend the fire from beyond the sauna wall

The Cozy Heat SW Thru-Wall Sauna Stove is a floor standing wood burning sauna stove. You load wood and remove ash from a changing room or outdoors, so logs stay out of the path past the benches. A steel extension carries the fire chamber through the wall, while the stove and stones sit inside the sauna. Curved steel slats surround the stones, with gaps showing the stones between them. The slats rise to their tallest point at the back.

The smaller size takes logs about 13 inches long, and the larger takes logs a little under 16 inches. Choose 12 kW for 210 to 423 cubic feet or 18 kW for 318 to 636 cubic feet. Stones are essential and sold separately by the box on this page. The chimney is also sold separately. Prefer to load wood inside the sauna? See the [Cozy Heat SW Sauna Stove](https://norsesteam.com/product/cozy-heat-sw-sauna-stove-wood-burning-sauna-stove-up-to-18kw/). The Cozy Heat SW Thru-Wall Sauna Stove ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
