I love frosted glass, for showers, for water closets, for doors interior and exterior. Here's a pocket door with frosted glass for a master bathroom, part of a renovation project bringing a 1928 house back to historical integrity while adding contemporary features. Not my cup of tea, but it is lovely.
we ordered a door from Home Depot that had 5 frosted glass panels in it. Perfect for letting light radiate through, but also enough to give anyone in the bathroom the privacy they need. - See more at: http://www.thehouseofsmiths.com/2014/05/our-master-bathroom-sliding-door-basin.html#more
