Bathroom faucet shopping trips up more people than kitchen faucet shopping, and it almost always comes down to one confusing word: configuration. Widespread, centerset, single-hole — these terms describe how the faucet mounts to your sink or countertop, and getting it wrong means a faucet that simply won't fit. Here's a clear breakdown from The Fixture Physician so you order the right one the first time.
It All Comes Down to Hole Spacing
Bathroom sinks and countertops are drilled with mounting holes, and the distance between them — measured from the center of the outer holes — determines which faucets fit. The three main configurations are single-hole, centerset, and widespread.
Single-Hole Faucets
As the name suggests, a single-hole faucet mounts through one hole. The spout and a single handle are combined into one unit. Benefits:
- Cleanest, most modern look
- Easiest to install and clean around
- Perfect for compact powder rooms and contemporary vanities
Many single-hole faucets include an optional deck plate, so they can also cover a three-hole sink if you change your mind later.
Centerset Faucets
A centerset faucet fits a three-hole sink where the outer holes are 4 inches apart. The spout and handles are mounted on a single base plate, so even though there are two handles (or one handle with a decorative base), it installs as one connected unit. Centerset faucets are:
- Common on standard and smaller vanities
- A familiar, traditional look
- Easier to install than widespread because everything is connected
Widespread Faucets
A widespread faucet also uses three holes, but the spout and two handles are separate pieces, with the outer holes typically spaced 8 to 16 inches apart (adjustable within that range). This is the upscale, custom look found in primary bathrooms across the Peninsula. Benefits:
- Premium, designer appearance
- Flexible spacing to fit larger vanities and vessel sinks
- Easier to clean between the separate components
The trade-off is a slightly more involved installation, since the three pieces connect beneath the deck.
Don't Forget Wall-Mount
For vessel sinks and freestanding tubs, a wall-mount faucet skips deck holes entirely and mounts on the wall above the basin. It's a stunning, space-saving look — but it requires in-wall rough-in, so plan it during a remodel.
How to Measure Before You Buy
If you're replacing a faucet and keeping the sink, measure first:
- Count the holes. One hole or three?
- Measure center-to-center on the outer holes. 4 inches means centerset; 8+ inches means widespread.
- Check the spout height and reach against your sink and any mirror or backsplash behind it.
If you're choosing the sink and faucet together for a remodel, you have full freedom — just make sure the sink's drilling matches your chosen faucet configuration.
Brands and Styles
All the major brands offer faucets in each configuration. Moen, Delta, and American Standard cover the practical middle, while Brizo, hansgrohe, and TOTO bring design-forward widespread and single-hole options for primary baths. You can compare configurations and finishes on our products page.
Spout Height, Reach, and Sink Type
Configuration tells you how a faucet mounts, but you still have to match the spout to the basin. Three pairings come up constantly in Bay Area bathrooms:
- Vessel sinks sit on top of the counter, so they need a tall faucet with enough height and reach to pour cleanly into the raised bowl. A standard-height faucet will splash off the rim. Many manufacturers make dedicated "vessel" single-hole faucets for exactly this.
- Undermount and drop-in sinks work with standard-height faucets. Just confirm the spout reach lands the stream near the drain, not the front rim.
- Pedestal sinks are usually pre-drilled for either single-hole or 4-inch centerset, rarely widespread — check the sink's drilling before you buy.
One Handle or Two?
Configuration and handle count are related but not identical. Single-hole faucets are almost always single-handle. Centerset faucets come as two-handle or as a single-handle unit on a base plate. Widespread faucets are two-handle by definition, with the handles physically separate from the spout. Single-handle operation is quicker and easier for kids and anyone with limited grip strength; two-handle gives precise, classic temperature control and a more traditional look. Neither is "better" — it's about how your household uses the bathroom.
Replacing an Old Faucet Without Surprises
If you're swapping a faucet on an existing sink, the safest path is to match the configuration you already have so the holes line up. Going from centerset to widespread, or vice versa, usually isn't possible without a new sink or counter, because the hole spacing is fixed. The exception is moving to a single-hole faucet with a deck plate, which can cover an existing three-hole 4-inch sink for an updated look without replacing the basin.
Finishes and Coordinating the Bathroom
Whichever configuration you choose, the finish ties the room together. Coordinate the faucet with your cabinet hardware, towel bars, and the trim on your shower and tub for a cohesive look. Chrome and brushed nickel are timeless and forgiving; matte black and brushed gold make a bolder statement. In a widespread set, remember that the spout and both handles should share the exact same finish — mixing even slightly different shades of "brushed nickel" between pieces looks like an accident rather than a choice, so buy the spout and handles as a matched set from one brand.
