Q. Do all faucets fit all bathroom sinks and tub/showers?

A. Yes. Standard-size sink openings and faucet dimensions are used throughout the plumbing industry, and flexible hook-ups allow for variability. However, since there are a few exceptions, it is a good idea to check sizes first. For single-handle tub/shower faucets, the existing opening must be smaller than the faceplate of the new unit.

Q. Can I replace a two- or three-handle faucet with a single-handle model?

A. Single-handle bathroom sink faucets use 4-inch centers, which is the distance between the centers of the hot and cold inlets or mounting bolts. Some two-handle faucets also use 4-inch centers and can, therefore, be replaced by a single-handle model. However, wider spreads are common so be sure to check your size before purchasing a new faucet.

Two- and three-handle tub and shower faucets can be replaced with a single-handle faucet but pipe changes are necessary. The wall opening will have to be enlarged slightly for this but can be covered by special plates, such as the Moen Remodel Cover Plate, that allow you to keep your existing tile or wall covering intact.

Q. Can a new tub/shower faucet be connected to my existing shower and tub spouts?

A. Yes. And this can have a safety benefit as modern shower valves, such as Moen's Posi-Temp and Moentrol, are pressure balancing. That means they control water temperature within +/-2¡ F to help prevent hot or cold water surges such as when a toilet is flushed.

Q. Can I use my existing drain assembly when installing a new faucet?

A. In most cases, yes. But if you're changing finishes, e.g. chrome to brass, you'll probably want to change the drain assembly.
