About faucet installation
A faucet is the fixture you reach for dozens of times a day, so installing a new one is a small project with an outsized payoff in how a kitchen or bathroom feels and works. The work falls into two parts. The first is choosing a faucet that actually fits, which is more about the sink's hole layout and the type of faucet than the finish or brand. The second is the connection underneath: shutting off the water, mounting the new faucet, and hooking up the supply lines so there are no drips once the water is back on.
Kitchen and bathroom faucets are not interchangeable. Kitchen faucets sit taller, often include a pull-down or side sprayer, and may tie into a disposal or a water filter. Bathroom faucets are sized to the sink's hole spacing, whether that is a single hole, a four-inch centerset, or an eight-inch widespread layout. The connections matter too: the under-sink shutoff valves and the flexible supply lines are easy to refresh during the swap, and replacing tired ones then is far simpler than after a leak appears. Plumbing Advisors is a national service that helps you confirm compatibility and connects you with plumbing professionals who handle the installation in your area.
When a faucet installation makes sense
The old faucet leaks at the base
When water seeps from where the faucet meets the sink rather than the spout, the seal underneath has usually failed. That is hard to repair reliably, so installing a new faucet is often the cleaner fix.
You are remodeling or replacing the sink
A new sink or countertop is the natural moment to fit a new faucet, since the old one may not match the new hole layout. Doing both together avoids fitting a faucet twice.
You want new features
A pull-down sprayer, a touchless handle, or a filtered-water tap are common reasons to upgrade. These features are easiest to plan for before the install so the right model and fittings are ready.
The finish is worn or dated
Pitting, flaking, or a finish that no longer cleans up can make a faucet look tired even when it still runs. A new fixture refreshes the look of the whole sink area for a modest cost.
Repairs keep adding up
If a faucet has needed repeated cartridge or seal work, or parts are getting hard to find, a new one can be the better long-term value than another repair on an aging fixture.
The hole layout no longer suits you
Switching from separate handles to a single-handle faucet, or covering unused holes with a deck plate, is straightforward during an installation. It is a chance to match the faucet style to how you actually use the sink.
What to know
When you need it
- You are upgrading an old or worn-out faucet
- A new sink or countertop needs a faucet fitted
- You want a pull-down sprayer, touchless, or filtered model
- The current faucet leaks at the base and is not worth repairing
Common causes
- An aging faucet at the end of its lifespan
- A kitchen or bath remodel changing the fixtures
- A new sink with a different hole layout
- Wanting added features like a sprayer or filtered water
- A leak where the faucet meets the sink that repair will not fix
What to check first
- Count the mounting holes in the sink or counter (one, three, or four)
- Measure the spacing between the outer holes for bath faucets
- Check that the under-sink shutoff valves turn and hold
- Note whether the supply lines reach and are in good shape
When to call a pro
- The new faucet's hole layout does not match the sink
- The shutoff valves are stuck, corroded, or will not seal
- The supply lines are old, too short, or the wrong fittings
- You are adding a sprayer, filtration, or a touchless model
Choosing the right faucet for your sink
The faucet that fits is decided mostly by where it is going and how many holes the sink has. A professional can confirm compatibility before anything is bought.
Kitchen faucets
Kitchen faucets stand taller to clear pots and usually offer a pull-down or side sprayer. Many install in a single hole, often with a deck plate to cover extra holes, and some pair with a separate soap dispenser or filtered-water tap. Match the number of holes and decide on sprayer and filter features before buying.
Bathroom faucets
Bathroom faucets are sized to the sink's hole spacing. A single-hole faucet fits one opening, a centerset suits holes about four inches apart, and a widespread faucet needs separate holes eight inches or more apart. Measuring the spacing is the key step, since a mismatch will not mount correctly.
Shutoffs, supply lines, and add-ons
Whatever faucet you choose, the under-sink shutoff valves and flexible supply lines are part of the job. Refreshing old, corroded, or stiff valves during the install prevents future leaks, and a filter or sprayer is far easier to fit while the connections are already open.
What a typical faucet installation visit includes
- Confirming the sink's hole configuration and that the new faucet fits
- Shutting off the water at the under-sink valves and relieving pressure
- Removing the old faucet and cleaning the mounting surface
- Mounting the new faucet and securing it to the sink or countertop
- Replacing the supply lines and, if needed, the shutoff valves
- Connecting any sprayer, soap dispenser, or filtration that comes with it
- Turning the water back on and checking every connection for leaks

Frequently asked questions
How do I know if a new faucet will fit my sink?
It comes down to the mounting holes. Count how many holes your sink or countertop has, usually one, three, or four, and for bathroom faucets measure the spacing between the outer holes. A single-hole faucet often includes a deck plate so it can cover three holes, but a widespread faucet needs the holes spaced to match.
Should the shutoff valves be replaced when installing a faucet?
Not always, but it is often a good idea. The under-sink shutoffs are right there during the job, and old valves that are stiff, corroded, or will not seal are far easier to replace then than after a leak starts. New supply lines are inexpensive and worth installing at the same time.
Can I add a sprayer or water filter during installation?
Often, yes. Many kitchen faucets come with a pull-down or side sprayer built in, and an under-sink filter or a separate filtered-water tap can be added if there is an open hole or room to drill one. It is worth deciding on these features before the install so the right fittings are on hand.
What is the difference between a centerset and a widespread bathroom faucet?
A centerset faucet combines the spout and handles on one base, typically for holes four inches apart, while a widespread faucet has separate pieces for holes spaced eight inches or more. The sink's hole spacing determines which style fits, so it is the first thing to check before buying.
