Warranty: every traditional cabin
The warranty term on every traditional cabin, and who stands behind it.
Warranty terms run 2 to 3 years across the 190 traditional cabins, with 1 covered for life. 168 carry no clean term, so the manufacturer's own wording is shown instead of a number.
How these are worked out
The term comes from the record. What a term actually covers is a brand promise rather than a product one, and it is rarely one number: a cabinet, a heater, controls and glass are usually covered for different lengths of time. Each brand page carries that full table with the date it was captured, so the brand here is a link to it rather than a summary of it.
Assumptions: electricity at $0.17 per kWh (US average), cost per session over 3 years at about 1 session per week (price divided by 156), sauna running cost at a 30-minute session. These are estimates for comparison, not quotes.

| Ownership | What it means |
|---|---|
| Upkeep | Two 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 rebuy | Sauna stones (checked yearly, replaced as they crumble), Exterior stain or sealant with UV inhibitor (every 2 to 4 years) |
| Where they fail | Stones 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 |
These apply to the class, not to this record alone, and they are sourced from the manufacturer guidance for it. Anything a source does not state is left out rather than estimated.
