Method, as of 2026-09-21: 41 Helsinki public or rentable sauna venues were found and verified independently of Service Map, from municipal and operator pages. Each Service Map result for the exact query “sauna” with a Helsinki address was then classified by hand. The other 13 results are shops selling sauna goods, place-name matches such as Saunalahti, member-only or restricted saunas, and units whose sauna could not be verified. Service Map and LIPAS (both CC BY 4.0) are used here only to measure coverage; no row below is copied from them.
