    Harvia WL590 Protective Sheath for Harvia Pro 20 RS/LS

    A model-specific black steel sheath for the Harvia 20 RS/LS Pro. Harvia’s own safety-distance table drops the side and rear clearance from 11.9 in bare to 2.5 in with the sheath fitted, and asks for 16.7 in at the front instead of 11.9 in. 25.6 x 22.5 x 32.3 in, 18.73 lb, ships with its installation and operation manual.

    Built for

    • Harvia Pro Series

      Harvia Pro Series
      The Pro line page, where the Pro 20 RS and Pro 20 LS this sheath is cut for are sold. Our page describes the Pro Series as the value line for medium saunas, with options like built-in water tanks (ES) and through-wall feed (SL), and notes it has “great short clearances when paired with the surround and floor protector”.

    What’s included

    • Protective sheath, black
    • Installation and operation manual

    Wood stove clearances exist because of radiation. The casing beams infrared at the nearest surface and a timber wall absorbs it. A sheath is a steel plate that takes that radiation instead, with an air gap behind it so convection carries the heat away rather than the wall soaking it up.

    Harvia’s description of this one: it is “designed and approved for wood-heated Harvia wood burning heaters such as the Harvia 20 RS/LS Pro” and “considerably reduces the safety distance to combustible materials”. Note that it is model-specific, cut for that stove, not a universal panel.

    What it buys you, in Harvia’s numbers

    Clearance 20 RS/LS Pro bare With WL590
    Side (B) 11.9 in 2.5 in
    Rear (C) 11.9 in 2.5 in
    Front (D) 11.9 in 16.7 in
    Ceiling (A) 51.2 in 51.2 in
    Gap behind sheath (F) — 1.2 in

    Note the trade. The sheath buys back the sides and the rear, and Harvia asks for more room at the front. Plan the bench layout around that before you commit, and check the ceiling height separately, the sheath does not change it.

      PLAN THE WHOLE SAUNA

      The room and heater still have to work as one system.

      Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.

      Compare sauna heaters

      See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
