Installing privacy curtain for rp 178

If you want it to stay there, adhesives are not a good option. Screws (anchors better) are better. however, if you can find a spring tension shower rod, consider that instead. Look at my mods. Go wall to wall with a small bracket to make sure it stays there. You will be happier with that, I think. Look at my mods to see what I did. I don't remember which post, but it is in there somewhere.

We added a tension rod in the bathroom in a 177 nine years ago to give extra space for drying wet towels and additional room for drying wet clothes.  No damage or wall 'separation' after 9 years; you should be good with the tension rod(s) for your application.
