We had one of these bathrooms last year but where the glass is in front of the wash basin they had a blind. Maybe they realise that people don't care for these bathrooms?
We had one of these rooms in building 5. You just have to swing the shower door in front of the toilet. The shower door is frosted, so it gives some privacy. We also tried to use the toilet when the other person wasn't in the room.
Sometimes we found the door to be more of a hindrance than a help. I stubbed my toe a few times on the door. D
