imo this is what locker rooms are for.
the design can have a lot to do with it though. the old YMCA near me was downtown and had a locker room with multiple rows of waist/chest high lockers in an otherwise open space, and communal pole showers. made it easy to be social. its demolished, the replacement is outside the city center, a weird alienating locker room design and only private showers.
