Germany
Oer-Erkenschwick is a city of 30,000 in the Recklinghausen district, at the northern edge of the Ruhr conurbation. A former mining town now characterised by residential suburbs, its sauna scene is part of the Ruhr's dense network of public leisure centres and Freizeitbäder that serve the region's high-density population. Larger sauna destinations in Recklinghausen, Gelsenkirchen, and Münster are accessible within 20–30 minutes. German textile-free norms apply; Aufguss on published schedules.
Aquarell leisure pool has a sauna section. For better options, Recklinghausen (10 km east) and Dortmund (25 km east) have larger Saunalandschaft facilities.
No — a local option for residents. International sauna visitors to the Ruhr will find meaningfully better options in Dortmund, Düsseldorf, or Cologne.
The post-coal identity of the western Ruhr has driven some investment in leisure as economic alternatives. But sauna provision here remains standard municipal-pool format.
