If your bathroom door swings inward and a pocket door isn't an option, consider flipping it around so that it opens out away from the room. Yes, it will require some work on the framing around the door, but it can be worth it to not have to try to scoot around the door when it is open and taking up space in your room. You also might need to open your door with a little more caution to avoid whacking someone coming down the hall — but this may be an acceptable trade-off when you are desperate for a little extra room. Tip: Let your door do double duty as a message center or a full-length mirror. If family members get ready at different times of the morning, this is a perfect spot for everyone to post messages. If you need a full-length mirror and don't have wall space for one, then putting a mirror on the door also would be a great idea.
I like the idea of a chalk panel somewhere I each kids rooms so they can doodle, write song lyrics and hateful angry teen msgs to us ;) at least we would kno what's in their heads ;)
