Before and After- Bathroom Window
A great way to let light in and maintain privacy: Artscape are available at Home Depot for around $20. Perfect for bathrooms, there are many designs to choose from and are easy to install and remove (no adhesive). My only tip would be to cut them a little larger as they shrink a bit from the moisture and steam.
P.S.- The Crescent Rod also seen in this picture is one of the best inventions ever(I got mine at HomeGoods for $20. It gives a regular sized shower a roomy feel. That and the attack of the plastic shower liner saga is officially over!
