Hey kenda,

Check out StreetComplete 61.2
https://github.com/streetcomplete/StreetComplete/releases/tag/v61.2

There are now more quests available for toilets and showers, so you should also be able to check i.e. if the shower next to it still exists (at least, it should ask for it, it hasn't been updated in 9 years..)

(of course many toilets and showers are usually permanent.)

Regards,

Daniel
