Description
The Harvia Legend Duo is a wood-burning sauna stove and fireplace in one. The Legend stone cage sits in the sauna, and a fireplace front with a large glass door opens into the adjoining room, where you load the wood. Sauna stones are included.
Two rooms
The sauna side heats the stones while the fireplace side gives the next room the view and warmth of a fire. Loading from outside the sauna keeps wood and ash out of it.
Build
It is made in Finland with a black steel stone cage that takes a large load of stones, a minimum of 572 lb. The grate is designed for cleaner, more efficient burning. It has adjustable legs, a door that can open either way, upper and rear flue openings, and a soot opening for cleaning.
Choosing an output
The 21 kW model suits rooms up to 848 cubic feet and the 23.5 kW model suits rooms up to 1,059 cubic feet.

Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- The Legend Duo is a sauna stove and fireplace in one: the stone cage sits in the sauna, and the glass fireplace front opens into the adjoining room, where you load the wood.
- The 21 kW model suits rooms up to 848 cu ft and the 23.5 kW up to 1,059 cu ft. It takes at least 572 lb of stones, which are included.
- It has upper or rear flue openings, a door that opens either way and adjustable legs, which gives you some freedom when planning the wall and chimney.
- Clearances to walls, ceiling and benches come from the installation manual, and a wood stove also needs a proper chimney run. Check local code and your insurer before you build around it.
- It usually ships within 1 to 3 business days and arrives in about 5 to 10 business days, so it can be on site before your build is finished.
