        I have an older bathroom sink, and am trying to replace the faucett. There are three holes, but the middle hole is only a 1/2 inch diameter. On the previous faucett, the only thing that went through the middle hole was the “pop-up” thing for the drain.

        I can’t find any new faucetts where the pop-up goes right down the center (they all require a center hole that is at least 3/4 inches in diameter).

        Any ideas on this one?

            Mike is correct. The Lav you have was a modification of the old style two faucet (hot and cold) design with the addition of a central drain stop lever. This was NOT the current design with a central mixer spout.

            The only way you can make this work is to use older style fittings. You cannot make it work as a mixer with current fittings, unless you can somehow enlarge the central hole.

              If you can get the porcelin away from hole you can use a hole saw and cut the hole bigger. You have to make a wood template and fasten it to lav. and use that as a guide. The only way to get porcelin off is use a chisel, protect your eyes.
