Hi,

A contractor built these very unattractive cubby holes in our bathroom
wall so we came with this brilliant idea to have custom made hammered
copper inserts and had those made in Mexico at a considerable cost. Of
course, they were made larger than the specs and they do not fit. I
can see the picture here.

My first reaction is to grind the tile down a little bid around the
edges (only the edges of pieces facing the viewer) and I think that
might just get them in there.

Is there a tool that would do it for me "in place"? I do recall
drilling 1/4" holes in these tiles and that taking me about an hour
per hole so I'm apprehensive about the strength of the material. So
I'm open to ideas!

Thank you very much in advance,

Aaron Fude.
