I have an old tub with a 2 valve shower faucet with diverter. The
valves are 10" center to center, and I haven't been able to find a
replacement with this dimension. Everything seems to be 8" on center
now, so if I can't find one of the proper size, then I will have to
mess up the tile--something I would prefer not to do.

Does anyone know where I might find a 10" unit online? If not, are
there any options other than ripping out the tile and starting over?

All suggestions appreciated.
