The tiny hall baths on the main floor of many homes constructed within the last 10 or 15 years are paralyzingly boring.  The ceilings are often high, but the walls are narrow.  I see a lot of hall baths with zero personality.

I have an easy fix.  Add a chandelier. 

Simply remove the light fixture above the mirror.  Choose a chandelier that suits your decor.  Smaller versions are better.  The faceplate can be mounted on the wall where the old fixture was wired.  Install a heavy plant hook to the ceiling and string the chandelier cord over the hook so that it hangs directly over the sink.  (High enough to avoid tall person head collisions.)

Add an interesting color, or better yet some wallpaper, and problem solved!
