We chose shower curtain for our tub/shower combo in the hall bath. In my opinion, glass looks nice but for a tub, it restricts access too much, particularly for bathing small children when you want full access. For our master shower, which is a shower only, we are going with frameless glass (still undecided on slider vs swinging doors but that's another topic ...)

it depends who will use it and how. if its only adults showering, then glass is nice. but if you ever want to take a bath, or will bathe small children, a shower curtain is nicer.

If you are not worried about bathing kids I like just a glass shower screen and a sqeegee that should be used after anyone showers. I think shower curtains get yucky really fast and so i would always be washing it.

linlac i agree its a lovely look. but you still need a plastic liner if you are going to shower with it.
