What owning infrared cabins involves
OwnershipWhat it means
UpkeepThere is no water and no stone bed, so upkeep is the cabin and the emitters. Benches and backrests are wiped down after a session, and the emitter faces are kept clear of dust. Inside, nothing is sealed: sealant and wood protectant are not used anywhere in a sauna, and tired wood is sanded back instead.
What you rebuyNothing
Service lifeCarbon fibre and full-spectrum emitters are rated 30,000 to 50,000 hours, which Sun Home puts at 15 to 25 or more years on three 45-minute sessions a week. Ceramic elements are rated far shorter, 5,000 to 10,000 hours, so the emitter type is what sets the replacement clock.
Where they failHeat output falling below 85% of baseline, the point at which Sun Home puts an emitter due for replacement; Visible cracking of an emitter face; An unexplained rise in energy draw with no change in use

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.
