I used some grab bar wingits in a tiled wall...solid as a rock! Note, though, you must position them VERY carefully (depending on the bar you use), as they WON'T move once you install them, and most grab bars don't have slots for the screws. The grab bars they sell have a small slot that will give you a little leeway. I used a polished stainless steel bar...really hard to tell from polished chrome.
