Finnleo Laava 10.5 kW (240V 1PH) Sauna Heater

Finnleo Laava 10.5 kW (240V, 1-Phase) Floor-Standing Electric Sauna Heater

The Finnleo Laava 10.5 kW sauna heater is a high-performance, floor-standing electric heater engineered for extra-large residential saunas and standard commercial sauna installations. Designed to deliver powerful, even heat while occupying minimal floor space, the Laava is one of Finnleo's most efficient large-format heaters, making it an ideal choice for spacious home saunas, spas, gyms, and wellness facilities that demand consistent high-volume heat output. Within the Finnleo electric heater lineup, the Laava sits above the wall-mounted Designer and Himalaya models and below the larger Magma heater, positioning it as the go-to choice for sauna rooms between 390 and 950 cubic feet.

Construction & Design

The Laava features a rugged, free-standing construction that is secured directly to the sauna floor rather than mounted to a wall, allowing it to safely handle higher wattages and larger rock loads than typical wall-mounted units. Its compact footprint (approximately 22" W x 22" D x 35" H) is designed to maximize usable sauna space while still supporting a substantial rock bed for superior heat retention and steam quality. Every Laava heater includes a built-in high-limit safety control that automatically shuts the heater off if the sauna room temperature exceeds safe operating limits, ensuring reliable and secure operation.

Rock Capacity & Heat Quality

This model holds up to 132 lbs of sauna rocks, the maximum rock capacity in its class, allowing more stones to sit in direct contact with the heating elements. This design produces a softer, more even heat and better steam response when water is ladled onto the rocks, delivering the classic, authentic Finnish sauna bathing experience. Rocks are included with every Laava heater package.

Power & Sauna Sizing

At 10.5 kW and 240V single-phase power, this Laava configuration is sized for sauna rooms ranging from approximately 390 to 950 cubic feet, making it suitable for large custom home saunas as well as standard-sized commercial sauna rooms. The Laava series is also available in 12.0 kW and 14.4 kW outputs, and in both single-phase and three-phase electrical configurations, so bathers and installers can match heater output precisely to room volume and available electrical service.

What's Included

• 1x Finnleo Laava 10.5 kW electric sauna heater (240V, single-phase)
• Sauna rocks, included at the heater's full 132 lb capacity
• Built-in high-limit safety shutoff control, factory-installed
• Installation and owner's manual with wiring and clearance guidelines
• Manufacturer's factory warranty

Note: the Laava is offered as a heater-only purchase or bundled with the required SaunaLogic2 (SL2-C) control and matching contactor box. Because the heater will not operate without a compatible control and contactor box, be sure to select a bundled package or order these components separately if choosing the heater-only option.

Controls & Operation

The Laava heater is designed to work with Finnleo's SaunaLogic2 control system, allowing users to manage heat-up time, temperature, and run duration from a wall-mounted control panel or the SaunaLogic2 mobile app. A properly matched control and contactor box is required for operation, ensuring the heater's higher amperage draw is handled safely. Through the SaunaLogic2 ecosystem, sauna owners can also coordinate heater operation with compatible sauna lighting and audio components for a fully integrated, app-controlled sauna environment.
