In my much younger days (1970s-1980s) I sought out room without private baths because they were substantially cheaper. I don't do that now, and things may certainly have changed. Back in the old days, there was always a wash basin in my room. That took a lot of pressure off the hall bath, because one could brush teeth and wash face right in the room. I would be surprised if those wash basins have been ripped out, but I can't say for sure.
A few years ago I accepted a room with a private bath (which included toilet/wash basin/shower) down the hall. It was a lot more irritating than I thought it would be. Anytime I wanted to use it, I had to go through these steps:
Find room key and bathroom key (might have been the same key--I don't remember).
Exit room and lock door.
Walk down hall to bathroom.
Unlock bathroom.
Enter bathroom.
Lock bathroom.
Use bathroom.
Exit bathroom.
Lock bathroom.
Walk down hall to my room.
Unlock room.
Enter room.
Lock room.
It was a real drag. The one time I didn't immediately lock the bathroom (I was quickly returning to my room to grab something I had forgotten, like soap), a teenager from one of the other rooms on the floor (which had a private bathroom) popped in there before I could return. So it was obviously important to keep the bathroom locked if I wanted to have immediate access to it.
That private bath down the hall was in some respects more annoying than a shared bath down the hall. The latter are not kept locked when empty, so there's less fumbling with keys.
