Hey all!

I've just about finished remodeling my master bath and am trying to put the towel ring & towel rack up following Kohlers' instructions and their cheap wall anchors. Here's the problem: The instructions say to drill a 1/4" hole in the ceramic tile and install the wall anchor. I had my tile guy do it since he's the pro and I didn't want to break the nice tile work he did. Upon trying to install the post for the towel ring, the wall anchor just spun with the screw - no grip. As I pushed harder, it went halfway and then the wall anchor went through the wall. I have tried 5/16" wall anchors and pretty much everything else at Home Depot/Lowes. One person suggested Liquid Nails, however, after reading the instructions, it says not recommended for ceramic. Anyone have a magic suggestion?
