Product Highlights
21 kW Wood-Fired Output
The Legend 240 SL delivers 21 kW of heat output, making it well-suited for sauna rooms between 353 and 848 cubic feet with a minimum ceiling height of 72.8 inches. It reaches operating temperature efficiently and holds heat through the session via its large stone bed.
440 lb Stone Capacity
The generously sized stone bed holds up to 440 lbs of sauna stones (11 boxes recommended, sold separately), absorbing and radiating heat evenly for soft, sustained steam output well beyond the active burn period.
Handcrafted Patinated Steel Frame
Each Legend 240 SL is hand-forged by Harvia's master blacksmiths in Finland. The patinated black steel frame provides a distinctive, traditional aesthetic and is built to withstand sustained high-temperature use.
Cast-Iron Glass Door
The large cast-iron glass door provides a clear view of the fire, contributing to the traditional sauna ambiance. It is constructed to withstand sustained high-temperature operation without warping or degrading.
Extended Firebox
The firebox accommodates logs up to 15 inches (39 cm) in length and 3–5.9 inches (8–15 cm) in diameter, reducing the need to split wood into smaller pieces and supporting longer, more consistent burns.
Dual Flue Connection Options
The stove supports both top and rear flue connections, giving installers the flexibility to route the chimney based on the sauna room layout and local building requirements.
5 mm Fire Chamber Cover
The thick steel fire chamber cover is built for long-term durability, protecting the internal components from the sustained heat of repeated wood-burning sessions.
Manufactured by Harvia in Finland
Harvia has been designing and manufacturing sauna equipment in Finland since 1950. The Legend 240 SL reflects the same build standards and craftsmanship applied across the full Harvia product line.
