## Start with the heater, not the cabin Heat source decides your groundwork, supply and running costs. Electric heaters above roughly 6kW usually need a dedicated circuit, and in older properties that supply upgrade can cost more than the cabin. Gas and wood-fired options avoid that but introduce flue, ventilation and clearance requirements.
## Size honestly Most private saunas are used by one or two people. Larger cabins take longer to reach temperature and cost more to run.
## Position and access Consider distance from the house, changing and shower provision, drainage, and whether you will walk out to it in February.
## Before you buy, confirm with the supplier Cabin volume suitability, heat-up time, insulation build-up, certification, warranty terms, installation responsibility and lead time.
