Oh another thing I remembered is Home Depot sells window cling that looks like stained glass.

We bought some and put it in our bathroom window also. It was so easy to install and looks great. Let's in light but still you get a lot of privacy. It's more expensive than the faux stained glass, but goes up way faster. I mean it took less than 5 mins.
