My gym/swimming pool has only two private cubicles, so most of us get dressed in the open area. In my experience (I have several very obvious/large body scars) nobody notices, or if they do, cares.
I’ve recently signed up at David Lloyd, just for the pool, but have yet to go. I hope to goodness that there are more than 2 cubicles! I really do not do communal changing rooms any more, not that I was ever happy to use them.
I did have a ‘pre’ visit but was unable to see the pool or changing areas, since it was all being renovated.
