I love the notch they cut out. You know you're right, scubadave, I know in my parents' house there a bathroom door that only opens 90 degrees. Thinking about it, even if it was to code to be slightly less it just would look or flow right.
We had thought about a pocket door, but I've heard that they can be a pain in the butt, and we also would have to deal with an outlet and the main wall switch, and nowhere else to really put it. But it would definitely be nice to not have the door constantly hitting the shower door.
