My bathroom is tiled with an extremely ridged ceramic tile and I would like to mount a floating shelf on the wall.
Since the tile is ridged, the tiler is reluctant to drill holes in it for fear of tile breakage.
Do diamond drill bits work on ridged tiles?
Are there any other recommendations on how to mount such shelves (glue, plaster, etc.) onto ridged tile? The shelves are simple planks made of laminated wood, and when loaded will weigh about 4-5 lbs.
