Sink job hits a curve

Q: Hi, Ed. My husband and I have done some remodeling of our bathroom, which includes a new granite top, new undermount sink and a new faucet. The three faucet holes on the granite top were cut in a slight semicircle pattern to follow the sink and the middle hole is about three quarters of an inch behind the outer holes to follow that curved pattern. The faucet that we purchased requires three holes, which we have, but when we went to mount the faucet, we found the base and copper pipes are in a straight line and won't fit the curved hole pattern. Do we curve the copper faucet connections? What can we do to make this faucet fit? Linda (Alaska)

A: Hi, Linda. The short answer is that the faucet will not fit. But the long answer is that it's not all bad news. Let me explain. Bathroom faucets come in two basic mounting styles and sizes: deck mount or component mount. The spread size will usually be eight-inch or four-inch center set. Your issue is not the size, since your holes have been cut to match the faucet spread.

However, you are trying to install a deck-mount faucet on a countertop that will require a component-mount faucet. Deck-mount faucets are on a straight rectangle deck that sits atop the counter. They are installed as one unit, usually ready to go right out of the box. Basically you are trying to fit a square peg in a round hole!

What you need to do is return the deck-mounted faucet, if you can, and purchase a component faucet with flexible water connections. Component faucets are just as the name says: Instead of being one unit, the faucet will consist of several pieces that need to be installed separately on each hole. The left hole will have the hot-water handle, the center hole will have the spout and the right hole will have the cold-water handle. Because they are three components, they will follow the curved hole pattern.

Under the sink, the flexible water lines can be installed to fit all the necessary water connections to the components. Usually lav sinks with pre-drilled holes can use deck mount or component faucets. Custom counter tops like yours usually will only accept component faucets, but they will give your bathroom a very nice look.

As you realize by now, getting a nice look does require some extra work and, on the average, installing a component faucet is usually twice the work of installing a deck-mount faucet.

Sorry, but this problem has no quick fix. Since the granite is already drilled, you seem to have gotten yourself in a hole and will have to start from scratch.
