How do you install handrails in tile?

Hold your ADA handrail where you want it. Pencil mark your hole pattern. They make drill bits to drill tile. I find the massonary style bit to work best. Dip the bit in water every once in a while to keep it cool. Drill a 1/4 " hole at each mark, tap in a blue "moly" in your FOUR locations. (use the 4 hole pattern) and screw your rail to the wall. ADA height is 34" to the center of the pipe. GL
