Bring your wood-burning sauna heater closer to surrounding surfaces without compromising safety. The Harvia Protective Sheath WL590 is a full protective enclosure specifically engineered for compatible Harvia 20 LS and Harvia 20 RS Pro wood-burning sauna heaters. By significantly reducing the required safety distance to combustible materials, it allows greater flexibility when designing smaller sauna rooms or maximizing usable interior space.
Manufactured from durable black-painted steel, the protective sheath is shaped to follow the contours of the heater, creating a clean, integrated appearance while maintaining Harvia's rigorous safety and performance standards. Because each sheath is designed specifically for its corresponding heater model, there are no compromises in fit, function, or heat protection.
The WL590 is available as a full protective sheath for complete coverage, while a separate one-sided protective sheath is also available for installations requiring protection on only one side of the heater. For a coordinated installation, pair the sheath with the Harvia WL100 Protective Bedding, designed to provide floor protection while matching the same premium black finish.
Whether you're building a compact home sauna, upgrading an existing installation, or creating a professional wellness environment, the Harvia WL590 Protective Sheath helps maximize space while maintaining the safety and craftsmanship expected from Harvia.
