Most Finns still go to a sauna weekly to supplement the modern daily showers. In Finnish cities, old apartment buildings don't have a sauna room in every apartment (like in the 1980s) or a time-shared sauna suite in every building (like since maybe the 1940s?). Instead, there were big public saunas in every block or so, and people went bathing there once a week.

In Helsinki, only a handful of those old public saunas remain today, but they are now protected by UNESCO and there's been a revival with several fancy public saunas built downtown in the last years, and the wood-heated ones are still considered the best: https://www.myhelsinki.fi/en/see-and-do/activities/the-best-...
