I do no think curtains are appropriate in a bathroom, although it could depend on the space. I like drapes in some rooms, although I also know they can "harbor" dust/mites/allergens regardless of what you do. (When I walk through homes with curtains in the bathroom, it does gross me out a bit.) Because our window is behind the tub/hard to reach and we don't have a pretty view out the bathrooms, we got frosted window glass. There is pretty natural light that comes through constantly, but we have privacy.

After reading all the responses it seems people are split between recommending shutters and roman blinds (cloth coverings in general). I have plantation blinds throughout my home and they give a very clean look that I like. I have not noticed that they block light. I also have not noticed my bathroom blinds collecting more gunk. It also could be that we do clean them regularly. Just a weekly wipe down keeps it all at bay. Having said that, your bathroom looks so serene and lovely. I can only imagine how beautiful the rest of your house is and I am anxious to see more of it as you decorate it (hint, hint)!! Enjoy your decorating!!

Plantation shutters would look great but they are also very expensive for that size window and we don't plan on staying here too much longer. My husband and I plan on selling the house within a couple of years so I have been looking for ways to do some updates. My style is more traditional with oil rubbed bronze fixtures and deep rich colors like browns, cremes and a touch of burgundy. I the colors I have a pretty solid decision on, just looking for ideas on the styles. Since the window is on the main floor and it on the front of the house, privacy is a must.
