The Finlandia FIN-45S Electric Sauna Heater is designed for home saunas from 100 to 210 cubic feet, delivering consistent, traditional Finnish sauna heat in a compact wall-mounted form.

Built with professional-grade stainless steel heating elements and components, the FIN-45S places sauna stones in direct contact with the heating elements for efficient heat transfer and even temperature distribution. Its triple-wall construction enhances safety by keeping surface temperatures lower while maintaining strong heat output.

With a large stone capacity for improved heat retention, the FIN-45S creates a classic sauna environment with steady, penetrating warmth. Designed and manufactured in Finland by Harvia, all Finlandia heaters are UL or ETL tested and listed for safety and reliability.

The FIN-45S is available in 240V single-phase or 208V three-phase configurations, with a stainless steel exterior. A compatible control unit is required for operation and sold separately.
