## Description

### Cozy Heat Thru-Wall Sauna Stove: keep firewood, bark, and ash outside the sauna

The Cozy Heat Thru-Wall Sauna Stove is a floor standing wood burning sauna stove. Its eight sided frame holds stones inside black steel mesh, while the fire door sits beyond the sauna wall. You load wood and remove ash from that side, keeping firewood, loose bark, and ash out of the sauna. The stove and stones stay inside. Choose the size to suit your sauna: 12 kW for 210 to 423 cubic feet or 18 kW for 318 to 636 cubic feet.

A steel extension of the fire chamber passes through an opening in a brick or concrete wall. A bare wood wall will not do. The stones cover the heater body, and you pour water over them for steam. Stones are required for use but 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 Sauna Stove](https://norsesteam.com/product/cozy-heat-sauna-stove-wood-burning-sauna-stove-up-to-18kw/). The Cozy Heat Thru-Wall Sauna Stove ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
