What owning traditional cabins involves
OwnershipWhat it means
UpkeepTwo jobs, on different clocks. The stones are checked at least once a year, rearranged, and any that have broken, crumbled or discoloured are replaced, which keeps the heater from working against a packed bed. The exterior is resealed or restained every 2 to 4 years with an exterior-grade product carrying UV inhibitors, sooner under strong sun, snow or coastal salt, with a look each year for fading and dry patches. Inside, benches and backrests are wiped down after a session and nothing is sealed: sealant and wood protectant are not used anywhere inside a sauna, and tired interior wood is sanded back instead.
What you rebuySauna stones (checked yearly, replaced as they crumble), Exterior stain or sealant with UV inhibitor (every 2 to 4 years)
Where they failStones crumbling into the heater bed, with broken pieces underneath as the tell; Discolouration or limescale on the heater elements, which Harvia gives as the signal to replace the heater; Exterior wood left unsealed past its interval, where fading and dry patches show first
