Get tension rods and get some curtains to gather on the rods...or you can buy some flat sheets and thread the rod through the hem. You can even buy a tablecloth and get the clip rings and hang it off the tension rods.

I don't know how nice the temporary solution needs to look. If looks aren't an issue, you can stick up most anything with painters tape that will be easily removable. Most hardware store carry the repositionable privacy film that you put up with soapy water, another easy fix.

Thank you, both. A privacy film on the lower windows combined with a cafe curtain and tension rod sounds like a really simple temporary fix.

Now on to the long-term plan ...

A roll of wax paper from the grocery store will solve the immediate problem - cut in strips and tape the wax paper to the glass.

White cafe curtains will give you the privacy you need. I took sheer white fabric triple the width of the window and shirred it on a rod. We have gone outside at night to with the lights on to test it and you see only vague shadows inside.

Thanks for the tip, graywings. I'm surprised that shirring white sheer curtains works for privacy. That would be great and may be our long-term answer.

Our painters still need to do some exterior work, so the wax paper might be our temporary fix on the upper windows while they're working on ladders outside our bathroom.

graywings - It's good you mention an important detail about your sheer white cafe curtains....the fabric is : triple width of the window. That gives it the fullness and all the folds. Nice pretty picture that shows the folds/fullness.
