Were the showers in your high school locker rooms private (separate stalls) or shared?

My high school had one big shower room with 3 shower heads.
My step daughter is in 7th grade and recently showered at school... her friends all wore swimsuits since it's a shared stall and they weren't comfortable being naked.

In college the shared showers had separate stalls and curtains.

My thoughts are that they should all have separate stalls... high school kids can be mean, and frankly even as an adult I'd have no desire to shower naked with other people.
