We have a porcelain tile shower and need to attach handicapped grab
bar. How do we drill this tile? Diamond bit? What do they cost? What
is procedure...small hole first then move to 1/8 bit?

The ohthers have good tips. Use a carbide tipped drill. To start with you
may want to use a center punch or other sharp harden tipped tool to break
the glaze of the tile. Don't hit too hard or you will crack the tile.
