We are tired of the shower organizers that hang from the shower head. IÂve found an online source for flat back ceramic shelves that can be mounted directly on top of existing tiles  but have been unable to find directions on the adhesive to be used or comments (pro or con) from anyone who has done this.

Our shower has the original 1960Âs tile set in the traditional cement/metal mesh/lathe and is solid as a rock. None of these tiles will ever just pop out so we could retrofit a set in shelf  so this is why we are looking into the flat back style.

I know I could contact the source or call a local tile store  but we were hoping that someone here has had experience w/ these. Any pics or opinions if you have added these?

Thanks!
