How we rank
The Recovery Space Score
Specific, currently-operating venues the public can book or walk into. Heritage bathhouses and modern recovery studios are scored on the same scale; beauty salons and medical-aesthetic clinics do not qualify.
Reach is log-scaled and recomputed from each venue's researched follower counts. The five judgment factors — legacy, experience, facility, community, destination — are calibrated across research segments so no category is scored on an easier curve. Counts marked verified were browser-checked at the listed date; the rest are approximate.
Details are editorial estimates (2026) and the ranking is reviewed monthly. Inclusion is not an endorsement; venues renovate, change access rules, and close — check before you travel.

Candlelit thermal-bath circuit in a landmark building, recreating Roman/Ottoman bathing tradition; day pass and treatment bookings.
