Suggestions for bathroom privacy? (Renting—no drilling)

My wife and I can make eye contact when one of us is in bed and the other is on the toilet. We don’t, because that’s weird, but it would still be nice to have some privacy. We’re renting, so installing a door isn’t an option. I previously put up long curtains on a shower rod, but it kept falling and I was worried that would hurt our small dog. I searched for some kind of wide roll-up blinds with suction cups that I could use sideways and hook when it’s closed, but no luck. Any suggestions?
