Finnleo Laava Sauna Heater

Finnleo Laava Sauna Heater Series

The Finnleo Laava Sauna Heater Series is a family of high-output, floor-standing electric heaters engineered for extra-large residential and standard commercial saunas. Built by Sauna360 in Cokato, Minnesota, the Laava concentrates serious heating power into a compact, minimal-footprint cabinet, giving sauna owners fast heat-up and consistent, authentic Finnish heat for larger rooms without sacrificing valuable floor space. The series is available in three power outputs—10.5 kW, 12.0 kW, and 14.4 kW—each offered in single-phase (240V 1PH) or three-phase (208V 3PH) configurations to match virtually any electrical setup.

Key Features (All Laava Models)

• Floor-standing design built for extra-large home saunas and standard commercial installations
• Compact footprint that delivers high heat output without crowding the sauna room
• Approximately 132 lb (60 kg) of sauna rocks included with every heater for deep, radiant, steady heat
• Rock capacity supports authentic Finnish löyly (steam) when water is ladled over the rocks
• Durable, corrosion-resistant heating elements designed for long service life in high-heat, high-humidity conditions
• Safety-tested and listed for use in North America
• Compatible with the SaunaLogic2® (SL2-C) control system for app-based, Wi-Fi-enabled operation
• Available as Heater Only or as a complete package bundled with the SL2-C control and matching contactor box
• Offered in single-phase (240V 1PH) or three-phase (208V 3PH) electrical configurations across all three power outputs

Laava Series Model Lineup

The Laava series covers a wide range of sauna sizes and electrical requirements. Choose the output and phase configuration that matches your room volume and available power supply:

• Laava 10.5 kW (240V 1PH) — Entry point of the series, sized for saunas from approximately 390 to 660 cubic feet.
• Laava 10.5 kW (208V 3PH) — Same heating output and room sizing as the 240V model, configured for three-phase commercial or residential electrical service.
• Laava 12.0 kW (240V 1PH) — Mid-range output for larger sauna rooms, extending coverage up to roughly 780 cubic feet.
• Laava 12.0 kW (208V 3PH) — Same 12.0 kW output on a three-phase circuit for facilities wired for 208V 3PH power.
• Laava 14.4 kW (240V 1PH) — The most powerful single-phase Laava, built for extra-large rooms up to approximately 950 cubic feet.
• Laava 14.4 kW (208V 3PH) — The top-output Laava heater in a three-phase configuration for large residential or commercial saunas.

Construction & Design

Every Laava heater shares the same floor-standing cabinet architecture across the series. The compact, upright housing is engineered to sit directly on the sauna floor, minimizing the footprint required inside the room while still holding a substantial ~132 lb rock load. This construction allows the Laava to deliver commercial-grade heat output in sauna rooms that would otherwise require a much larger or wall-mounted unit. The rock bed sits atop the heating elements, allowing heat to radiate evenly through the stones and enabling steam production when water is applied—preserving the traditional Finnish sauna bathing experience at scale.

Heating Performance

Because the Laava is available in three distinct power outputs, sauna builders and homeowners can size the heater precisely to the cubic footage of the room rather than over- or under-powering the space:

• 10.5 kW heaters are suited to rooms in the smaller end of the extra-large sauna range.
• 12.0 kW heaters step up output for mid-to-large rooms that need faster heat recovery.
• 14.4 kW heaters provide the highest output in the series, intended for the largest residential and standard commercial sauna rooms the Laava line supports.

All three outputs are available in either 240V single-phase or 208V three-phase wiring, so the electrical configuration can be matched to the building's existing service without changing the heater's performance characteristics.

Controls & Compatibility

Every Laava heater requires an SL2-C control and a matching contactor box to operate—these are not optional accessories but essential operating components sized to each heater's voltage, phase, and kW rating. Buyers can select:

• Heater Only — for installations where a compatible SL2-C control and contactor box are already in place.
• Complete Package — bundles the heater with the correctly sized SL2-C control (available in 60-minute mechanical-style or 24-hour Wi-Fi-enabled versions) and the matching contactor box for the selected voltage and phase.

The SaunaLogic2® ecosystem allows the Laava to be integrated with sauna lighting and audio, giving users a single app-controlled experience for start times, temperature, and ambiance across every model in the series.

What's Included

• Laava heater unit (10.5 kW, 12.0 kW, or 14.4 kW, in your selected voltage/phase configuration)
• Approximately 132 lb of sauna rocks
• Owner's manual and installation instructions
• Factory warranty coverage
• Complete Package option adds: SL2-C control (60-minute or 24-hour Wi-Fi) and the correctly matched contactor box for your heater's voltage and phase

Note: The SL2-C control and contactor box are required for operation on every Laava model and are not included with the Heater Only option—they must be purchased separately if not already owned.

Technical Specifications

Sauna room sizing scales with output, spanning approximately 390 to 950 cubic feet across the full Laava series, from the 10.5 kW entry model to the 14.4 kW top-output model.
