Construction & Design

The Laava's floor-standing cabinet is built to house a generous rock bed while keeping its footprint minimal inside the sauna room. Its construction concentrates heating power efficiently, producing the fast heat-up times and steady, radiant warmth associated with authentic Finnish sauna bathing. At 14.4 kW, this model is best suited to larger sauna rooms, rooms with higher heat loss, or commercial settings that need extra recovery speed between sessions. The compact profile makes it a practical fit for both custom-built and prefabricated sauna rooms.

Controls & Compatibility

The Laava 14.4 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.
