Construction & Design

The Laava features a rugged, floor-standing cabinet built to house a generous rock bed while maintaining a minimal footprint inside the sauna room. Its construction is designed to concentrate heating power efficiently, producing the fast heat-up times and steady, radiant warmth associated with authentic Finnish sauna bathing. The heater's compact profile makes it well-suited for both custom-built and prefabricated sauna rooms where space efficiency is a priority.

Controls & Compatibility

The Laava 12.0 kW requires the SL2-C control and a matching contactor box for operation. Buyers can choose a Heater Only configuration or a bundled package that includes the SL2-C control — available in 60-minute or 24-hour Wi-Fi enabled versions — along with the correctly rated contactor box for a 240V, 1-phase circuit. When paired with the SaunaLogic2® system, the heater can be integrated with sauna lighting and audio for a unified, app-controlled bathing experience.
