Changing a faucet may seem daunting, but it’s a relatively simple DIY project that can be completed in an afternoon. Whether you are replacing an old faucet or installing a brand new one, you can save money by handling the job yourself.

This guide will walk you through the process with the steps you need to successfully replace your bathroom or kitchen faucet.

How to Replace a Faucet in 8 Steps

Let’s look at the steps you should follow to replace a faucet in your bathroom or kitchen successfully.

Step 1: Gather the Tools You Need

First, you’ll want to ensure you have the following tools:

Adjustable wrench or basin wrench
Channel-lock pliers
Screwdriver
Plumbing tape (also called Teflon tape)
Towels or a small bucket
Pipe joint compound
Replacement faucet and necessary hardware

Step 2: Turn Off the Water Supply

Before you do anything, make sure to turn off the water supply to the faucet. Most sinks have shut-off valves, either beneath the vanity or behind the sink. Turn these valves clockwise to shut off the water.

Once the water supply is off, turn on the faucet to release any leftover water in the lines. This will prevent any unexpected spills when you disconnect the faucet.

A faulty water faucet is disconnected from the water supply to repair a leak.

Step 3: Disconnect the Water Lines

Before disconnecting the water lines, place a towel or a small bucket underneath the connections to catch any water that may leak out when you disconnect the lines. Then, use an adjustable wrench to loosen and disconnect the water supply lines from the faucet. These are typically located at the base of the faucet and connect to the hot and cold-water lines beneath the sink.

To get a better grip, you may need pliers or a basin wrench (which has a long handle for working in tight spaces).

Step 4: Remove the Old Faucet

Next, you’ll need to remove the old faucet. Faucets are usually held in place by a few screws or nuts located beneath the sink. You might need a basin wrench or an adjustable wrench to unscrew these fasteners.

Once you’ve removed the securing hardware, gently pull the faucet upward and away from the sink. If the faucet is stuck, it may be because of mineral deposits or corrosion around the base. In this case, try gently wiggling it or using a rubber mallet to tap it loose.

Step 5: Prepare the New Faucet

Before installing your new faucet, you’ll want to prepare the area to ensure a proper fit. Clean the area around the faucet hole in the sink to remove any old caulk, debris, or mineral buildup.

Most new faucets come with instructions, so follow the manufacturer’s guidelines for your specific model. Typically, you must install a gasket or rubber seal around the base to prevent water leaking from the faucet.

Step 6: Install the New Faucet

Place the new faucet into the sink’s faucet holes and secure it with the provided hardware. This often includes nuts or screws that need to be tightened beneath the sink. Use an adjustable wrench to secure these fasteners, but be careful not to overtighten them — the screws may become stripped and can damage the sink or faucet.

If your new faucet has a sprayer attachment, you’ll also need to attach the sprayer hose to it. Ensure all connections are snug and use plumber’s tape (Teflon tape) on threaded connections to prevent leaks.

Step 7: Reconnect the Water Supply Lines

Reconnect the water supply lines to the faucet by tightening them with an adjustable wrench. Ensure the connections are secure but not overtightened, as this can damage the threads.

If you’re using plumber’s tape, wrap it around the threads before tightening the nuts. This helps to ensure a tight seal and prevent leaks.

Step 8: Turn On the Water and Check for Leaks

Now it’s time to turn the water supply back on. Slowly open the shut-off valves and check for leaks around the faucet and water supply lines. If you see any leaks, tighten the connections with a wrench.

Turn the faucet on and let the water flow for a few moments to check if the water pressure is consistent and the faucet works properly. If everything is running smoothly, you’re done!
