The 2026 Sauna Index

Five honest cuts of the atlas — most affordable, best for contrast, on the water, broadest range, deepest heritage.

Published April 2026 · 88 curated venues · 7 of 57 cities qualify (≥3 venues) across 5 countries

The Sauna Index is our annual attempt to make the atlas citeable. Each ranking below is computed directly from the curated venue data — nothing is padded, and cuts we can't defend with the data we have (late opening hours, per-capita counts, first-timer friendliness) are left out entirely.

Cities with fewer than three curated venues are excluded from every ranking so the numbers aren't swung by a single operator. The methodology under each table names the exact field and rule we used; copy, paste, link to us.

Most affordable sauna cities

Cities ranked by the average listed price band across their curated venues — more £ pips filled in means a more expensive scene.

Amsterdam leads the atlas on affordability — its curated venues average 1.0 / 3 on the £–£££ price scale across 5 venues.

Methodology · Price-band mean: average of each venue's £/££/£££ price band (encoded 1–3), ascending. The pip bar shows this mean on the three-band scale; the number beside it is the raw mean. Cities with fewer than 3 curated venues are excluded so the mean isn't thrown off by a single operator.

Best cities for contrast therapy

Cities ranked by the share of curated venues that pair their sauna with an on-site cold plunge.

In Vancouver, 100% of curated saunas run a cold plunge on site — 6 of 6 venues.

Best cities for waterside sauna

Cities ranked by the share of curated venues that sit on a lake or sea — a session with an open-water plunge instead of (or as well as) a cold pool.

63% of curated saunas in Helsinki open onto lake or sea — 5 of 8 venues.

Most diverse sauna scenes

Cities ranked by the number of distinct sauna types represented across their curated venues — Finnish, smoke, floating, steam, and infrared.

Helsinki runs the broadest range in the atlas, with 2 distinct sauna types across 8 venues.

Cities with the deepest heritage scene

Cities ranked by the absolute number of curated venues tagged as historic — a measure of how many original or preserved bathhouses still trade.

Helsinki carries 2 historic venues of 8 curated venues — the deepest heritage stack in the atlas.
#CityHistoric venues
1HelsinkiFinland2
of 8 curated venues
Methodology · Historic count: absolute number of venues where `features` includes `historic`, highest first. We rank on count rather than share because heritage scenes are additive — one more preserved bathhouse matters even if the overall city has also added modern ones. Cities with fewer than 3 curated venues are excluded.

What we're not ranking in 2026: venues per capita (we publish the atlas we've curated, not a census), late-night availability (we don't parse opening hours into structured fields), and ratings or reviews (we don't collect them — curation is our signal). When new fields arrive we'll add new cuts; we won't retrofit them.

The index will be reissued each year under its own URL, so 2026 stays citeable even after 2027 ships. Data source: the live Ember atlas, as of publication.
