A leaking bathroom faucet is more than just a nuisance — it can waste water and increase your utility bills. Fortunately, with some basic tools and guidance, you can often repair a leaking faucet yourself. This step-by-step guide will help you stop annoying drips and restore your faucet to proper working order.

Gather Replacement Parts

Before diving into the repair, it’s essential to identify your faucet type. Most bathroom faucets fall into one of four categories: compression, ball, cartridge, or ceramic disc.

1. Inspect your faucet: Look for identifying marks or refer to the manufacturer’s manual to determine the type.
2. Purchase the right parts: Depending on your faucet, you may need a new cartridge or stem. Additionally, inspect the O-rings and seals — if they appear damaged, you’ll need to replace them.
3. Tools to have on hand: Gather an adjustable wrench, screwdrivers, pliers, and plumber’s grease.

Shut Off the Water

Always turn off the water supply before starting any plumbing repairs. Follow these steps to ensure the water is correctly shut off:

1. Locate the shut-off valves: These are typically under the sink. Turn them clockwise to stop the water flow.
2. Test the faucet: Turn the faucet on to ensure the water is completely off.
3. Protect your workspace: Place a towel or bucket under the sink to catch residual water.

Remove the Handle

Next, you’ll need to access the internal components of your faucet. Follow these steps to remove the handle:

1. Pry off the handle caps: Many faucets have decorative caps covering the screws. Use a flathead screwdriver to gently remove them.
2. Unscrew the handle: Use the appropriate screwdriver to remove the screws holding the handle in place.
3. Lift off the handle: Carefully pull the handle away from the faucet body.

Take Off the Cartridge

The cartridge or stem is often the culprit behind unwanted leaks. Follow these steps to remove it:

1. Inspect for a retaining nut: Some faucets have a retaining nut securing the cartridge. Use a wrench to remove it.
2. Pull out the cartridge: Gently wiggle and pull it out. If it’s stuck, use pliers for added grip.
3. Examine for damage: Check the cartridge or stem for wear and tear. Replace it if necessary.

Remove the Rubber Seals

Rubber seals or O-rings can degrade over time, causing leaks. Follow these steps to remove them:

1. Locate the seals: These are usually at the base of the cartridge or inside the faucet body.
2. Remove with care: Use a flathead screwdriver or pliers to remove the seals without scratching the surrounding metal.
3. Inspect the seals: Look for cracks or deformation.

Reassemble the Faucet with the New Replacement Parts

Now that you’ve replaced the damaged components, it’s time to put everything back together.

1. Install new seals and cartridges: Insert the new rubber seals and slide the cartridge back into place. Secure it with the retaining nut if applicable.
2. Reattach the handle: Screw the handle back on and replace the decorative caps.
3. Turn the water back on: Slowly open the shut-off valves and test the faucet for leaks.
4. Apply plumber’s grease: Lubricate any moving parts to ensure smooth operation.
