## Description

### Cozy Heat O Thru-Wall Sauna Stove: a round stone column with firewood kept outside the sauna

The Cozy Heat O Thru-Wall Sauna Stove is a floor standing wood burning sauna stove. Its round black steel mesh cage holds a full column of stones inside your sauna. A steel extension passes through the wall, putting the loading door and ash removal on the other side. That keeps the firewood mess out of the sauna room. Pour water over the stones for steam. The maker says its stoves use about a quarter less firewood than comparable sauna stoves.

Choose 12 kW for a sauna of 210 to 423 cubic feet, or 18 kW for 318 to 636 cubic feet. Stones are required and sold separately by the box on this page. The smaller size needs about 265 pounds, and the larger needs about 353 pounds. The chimney is not included. Prefer to load wood inside your sauna? See the [Cozy Heat O Sauna Stove](https://norsesteam.com/product/cozy-heat-o-sauna-stove-wood-burning-sauna-stove-up-to-18kw/). The Cozy Heat O Thru-Wall Sauna Stove ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
