I was looking at house design/style magazine and came across a bedroom with only a half wall on the ensuite shower room. It looks nice but it seems so impractical! Your whole bedroom would end up steamy and damp, surely? Although I guess the window will help but I wouldn't want to open it in winter!
Discussed with friends and we are split down the middle!
I don't think there was a loo in there as well, although it didn't say there wasn't and it's possible it's not just visible in the picture.
YABU - Open plan ensuite/shower room is fine
YANBU - Ensuites need doors
