I have slate tile on a wall in my bathroom and I want to mount a couple of robe hooks on this wall. My plan was to use a couple of spring toggles, as the wall is approaching 1" thick with the tile and backer board behind it. There are no studs where I want the robe hooks mounted.
The problem I've got is that the two holes in the robe hook bracket are only 5/8" apart on center. The smallest spring toggle available is 1/8", which requires a 3/8" hole to be drilled. I'm worried that drilling a couple of 3/8" holes through the tile that close together - leaving only about 1/4" of tile between the holes, edge to edge - will cause the tile to crack.
I know I can offset the holes a little bit to leave more material between the holes, but I don't have much wiggle room there either without the hole being exposed outside of the hook itself. At best, I might be able to leave 1/2" between the holes.
Any other suggestions from anyone? I'd really like to get away with drilling some smaller holes, but as far as I can find, I don't have that option with any other types of anchors that I can find. Or maybe I give up drilling all together and use some sort of adhesive?
