I'm putting up hooks on the tile wall in my bathrooom. I have to use hollow wall anchors because the tile is over drywall or possibly cement board. But, I'm having a problem. I've used these types of anchors in drywall many, many times with no problem. But with the tile, after I drill the hole the anchor won't fit into it. If i try to pound it in with a hammer the anchor just breaks. I'm using the drill bit size called for with the anchors. With drywall the anchors are able to bite into the wall some, but they can't do that with tile, hence they don't fit. There must be an obvious solution to this, but I can't figure it out. drilling a bigger hole would be an option, but I don't know how much bigger to go and it would seem that this should be something that would be mentioned on the anchor packaging.
Is there a particular type of anchor for tile walls that I don't know about?
