Picture this: the soft crackle of fire, the glow of embers, and the deep, restorative warmth that lingers long after you’ve stepped away. The Harvia Legend 240 Duo turns that feeling into your everyday ritual—a genuine Finnish sauna experience that fills two rooms with steady, soothing heat. This isn’t just a stove; it’s the centerpiece of a home built around recovery, calm, and connection.
Why do you think true sauna lovers insist on wood-burning heat? Because nothing matches the rhythm of real fire or the way it grounds you in the present moment. Every session becomes an act of balance, a reset that pays itself back in focus, energy, and peace of mind.
This isn’t a purchase—it’s a one-time investment in daily wellness. Built with a durable black steel frame and crafted in Finland, the Legend 240 Duo stands for reliability, craftsmanship, and endurance. It’s made to outlast trends and deliver years of restorative heat with minimal maintenance.
Imagine a few weeks from now: stepping into your sauna at dusk, the firelight flickering through the glass, warmth radiating from hundreds of stones. The air is quiet. The day releases its hold. You feel grounded, clear, and alive. That’s not luxury—it’s your new normal.

| C — stove to rear wall | 9.8" (250 mm) |
| D — stove front to opposite wall or bench | 24.8" (630 mm) |
Measured from the stove body to any combustible surface. A non-combustible wall behind a protective sheath may be closer — see the manual for sheathed installations. Always confirm against the Installation and Operation Manual linked below before building.
Safety Distances With the Legend Protection Supplies
| Clearance | Minimum |
|---|---|
| A — side wall to protective sheath WL200 | 1.2" (30 mm) |
| B — rear wall to protective sheath WL200 | 1.2" (30 mm) |
| C — ventilated gap between the WL200 sheath and the stove body | 2.0" (50 mm) |
| D — rear wall to smoke pipe cover WL300 | 6.5" (165 mm) |
These are the letters on the plan view below. Unlike the unprotected distances above, they are the same for every Legend model. The WL100 protective bedding, WL200 protective sheath and WL300 smoke pipe cover are sold separately. Always confirm against the Installation and Operation Manual linked below before building.
Minimum safety distances with various protection options:
Safety Distances by Protection Option
| Measured from | Minimum distance to a combustible wall or bench |
|---|---|
| Smoke pipe WZ050M, WZ100M, WZ45M, WZ90M, WZ90NM | 13.8" (350 mm) |
| Smoke pipe WZ115050, WZ115100, WZ11545, WZ11590, WZ115030SP | 19.7" (500 mm) |
| Steel chimney WHP1500 | 3.9" (100 mm) |
| Smoke pipe cover WL300 | 6.5" (165 mm) |

| Stove body, rear, without a sheath | 9.8" (250 mm) |
| Stove body, side, without a sheath | 7.9" (200 mm) |
The four views below are, left to right: an unprotected smoke pipe; a WHP1500 steel chimney with a WL300 smoke pipe cover fitted; the same with a WL200 protective sheath added; and that arrangement seen from the front, where the side with no sheath still needs its full distance. These distances hold only when the stones have been piled carefully enough to cover the stove body and the smoke pipe completely. The front clearance is not shown here and differs by Legend model — take it from that model's own safety-distance table. Always confirm against the Installation and Operation Manual linked below before building.
