Replacing triple handle shower/tub faucets

[Nussm]

Dear Terry:
We have an older bathroom with a three handled faucet, i.e.,two faucets and a diverter in the middle. The faucets are ten inch center! We have not been able to find a faucet that meets our specs yet. We do not want to change to a one faucet system, because of the expense of breaking tiles and having old holes in the wall to cover somehow. Any suggestions?
P.S. Can a pressure balancer be inserted in this type of older faucet?

Thnks for any help,

Marvin Nussbaum

You might look at "Sterling" faucets online . Have an older neighborhood that has all 11" centers and these are the only ones that will work.

Check with a couple plumbing houses. 12" is a special item , but I believe you can still get them. That would be my first choice.
