Harvia Warranty
When a Harvia Spirit is recessed into a bench, the HSP1 is the stainless flange that finishes the opening. Harvia’s description is that it ‘ensures a neat finish and also acts as a thermal radiation shield for your benches’; Note that it protects the bench structures from water and heat and that the stainless steel is easy to keep clean. It measures 22.44 x 17.32 in, weighs 1.43 lb, and is designed, engineered and made in Finland.

Harvia HSP3M Safety Railing for Harvia Spirit | Heat-Treated Birch
The companion Spirit fitting: a heat-treated birch railing that fastens to the heater and gives the room a touchable surface. See the full product and build your package →
Embedding a Spirit into a bench puts bench timber right up against the heater, and in the path of any water thrown at the rocks. The HSP1 is a stainless flange that closes that opening.
Harvia’s own wording is that the flange “ensures a neat finish and also acts as a thermal radiation shield for your benches”. It does two jobs: it protects the bench structures from water and heat, and the stainless steel is easy to keep clean. It is designed, engineered and made in Finland.
One thing to plan for: the flange finishes the opening, it does not create it. The bench cut-out has to be built to suit the heater, so bring the flange dimensions to whoever is building the benches rather than fitting it afterwards.

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