Its square tower of stones sits inside the sauna. The fire chamber extends through the wall, putting the door, wood loading, and ash removal on the other side. Stacked steel frames leave stripes of stones showing between them. The size options are 12 kW for 210 to 423 cubic feet and 18 kW for 318 to 636 cubic feet. Stones are required for use and sold separately by the box on this page. Water poured over them makes steam. The chimney is not included. You can add a KOLO bucket and ladle set or decorative stones. Norse Steam contacts you before shipping to discuss delivery. The stove comes by truck, and the driver lowers it to the curb. Prefer loading wood inside?
