I don't want to make it easy to peak behind and see shelving.

If you have stuff you have to hide here, well, maybe you have too much stuff?

And if they peek behind it and see shelving.....so what. They can just as easily open up a medicine cabinet....and...so what.

I live in a condo and storage is always a problem. Like the idea of white shade to blend in. Thank you all for taking the time to respond

i'd do the shade full length (to the floor).... it might be even less obvious. and make it washable since its that close to the toilet.

Thank you. I was thinking sliding doors. But starting to think white shade is good :)
