Its fire chamber extends through the wall, letting you add wood from the room next door. That keeps firewood and ash out of the sauna. The glass door has a cast iron frame and lets you watch the flames from the adjoining room. Designed and made in Finland, this 16.5 kW stove suits saunas from 212 to 459 cubic feet. The fire chamber extension comes with the stove. The stove needs two boxes of sauna stones, which are sold separately and can be added on this page. The chimney is not included, so you choose it on this page. You can also add a protective sheath, a shield that allows the stove to sit closer to wooden walls. Rather load wood inside the sauna? See the [Harvia M3 wood burning stove](https://norsesteam.com/product/harvia-m3-16-5kw-wood-burning-sauna-stove/), which is the same size. The Harvia M3 SL ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee. ### The Heart of the Sauna Be it an electric or a wood-burning heater, steamy or dry, one thing is for sure; it heals you.
