Frequently asked questions

What makes the Legend 300 Duo different from a standard wood burning sauna stove?

The 300 Duo is a two room heater and fireplace combo.
It allows you to enjoy a real fireplace on one side of the wall while heating your sauna on the other. This creates a relaxing, warm atmosphere outside the sauna while delivering authentic steam sessions inside.

What size sauna room is this stove designed for?

The Legend 300 Duo is ideal for rooms between 529 and 1059 cubic feet, making it perfect for medium to large saunas.

How many stones does this heater require?

This model requires a minimum of 572 lbs of sauna stones (approximately 13 boxes). The large stone capacity produces soft, rich, smoke sauna style steam.

What type of heat experience does the 300 Duo offer?

You can expect:

- Fast, powerful heating

- Moist, gentle steam similar to a traditional smoke sauna

- A long lasting heat cycle due to its massive stone volume

- Cleaner burning compared to typical wood stoves

Can I heat the sauna from outside the room?

Yes. The 300 Duo is designed so the firebox loads from outside the sauna, keeping ashes out of the sauna interior and offering a cozy fireplace view.

Is the stove easy to keep clean?

Yes. Because it loads from the outside, ash and debris never enter the sauna room. A soot opening makes maintenance simple and safe.

What materials is the stove made from?

The unit features a hand welded black steel frame that surrounds a large bed of stones. Its open stone design ensures efficient heat transfer and a unique aesthetic.
