How do I fix a leaky faucet in my bathroom?

Fixing a leaky bathroom faucet is a great DIY project that usually takes under an hour. The exact steps depend slightly on your faucet type, but the general process remains the same.

Tools and Materials Needed

• Adjustable wrench
• Hex wrench (allen key) set
• Flathead and Phillips screwdrivers
• Replacement parts (O-rings, washers, or a new cartridge depending on your faucet)
• Plumber's tape (Teflon tape)
• Old rag or towel
• Flashlight

Step-by-Step Repair Guide

1. Shut off the water supply
   Locate the shut-off valves under the sink (one for hot, one for cold) and turn them clockwise until tight. If there are no under-sink valves, turn off the main water supply to your house.
2. Drain the remaining water
   Turn on the faucet handle(s) to let any water left in the line drain out completely. Plug the sink drain with a rag so small screws or parts don't accidentally fall down the drain.
3. Remove the handle
   Look for a decorative cap or a set screw on the faucet handle. Pry off the cap with a small flathead screwdriver or loosen the set screw using an allen key or screwdriver. Lift the handle straight up to expose the internal mechanism.
4. Expose and remove the valve/cartridge
   Depending on your design, unscrew the retaining nut or retaining clip holding the internal cartridge or stem in place. Pull the cartridge, stem, or assembly straight out. You may need pliers or a special faucet wrench if it is stuck due to mineral buildup.
5. Inspect and replace worn parts
   Check the O-rings, rubber washers, or plastic springs inside. If you have a cartridge faucet, inspect the whole cartridge for cracks or wear. Pro tip: Take the old parts or cartridge to a hardware store to ensure an exact match when buying replacements.
6. Clean the valve seat
   Use a small brush, vinegar, or a rag to clean out any mineral deposits or debris inside the faucet body where the new washer or cartridge will sit.
7. Reassemble the faucet
   Slide the new cartridge, washer, or O-rings into place. Secure the retaining nut snugly—do not overtighten, or the handle may become too hard to turn. Reattach the handle and tighten its set screw or snap the cap back on.
8. Test the repair
   Turn the under-sink water supply valves back on slowly. Leave the faucet handle closed for a moment to check for any leaks around the base, then turn the water on and off to ensure proper flow and a tight seal.

If you'd like, let me know:

• What brand or type of faucet you have (single-handle, double-handle, or widespread)?
• Where the leak is coming from (the spout tip, or underneath the handle)?

I can give you more specific troubleshooting advice.

A leaky bathroom faucet is usually caused by a worn washer, O-ring, cartridge, or valve seal. The repair is often a small parts replacement rather than replacing the whole faucet.

What you’ll need

• Adjustable wrench or pliers
• Screwdrivers (Phillips and flathead)
• Allen key set (for some single-handle faucets)
• Replacement washer/O-ring or faucet cartridge (matched to your faucet)
• Towel or rag
• Plumber’s grease
• White vinegar (optional, for mineral buildup)

Steps to fix it

1. Turn off the water

• Close the hot and cold shutoff valves under the sink.
• Turn on the faucet briefly to release pressure and confirm the water is off.

2. Protect the drain

• Put a towel over the sink or plug the drain so small screws don’t disappear.

3. Remove the handle

• Look for a small decorative cap on the handle.
• Pry it off, remove the screw underneath, and lift off the handle.

4. Identify the faucet type

• Two-handle faucet: Often uses a worn rubber washer or stem seal.
• Single-handle faucet: Often uses a replaceable cartridge or O-rings.

5. Replace the worn part

• Remove the stem or cartridge.
• Inspect for cracked, flattened, or damaged seals.
• Replace the washer, O-ring, or cartridge with the same model/size.
• Apply a small amount of plumber’s grease to rubber seals before reassembly.

6. Reassemble and test

• Put everything back together.
• Slowly reopen the water valves.
• Check for leaks around the spout, handle, and faucet base.

If it still leaks

• A drip from the spout after replacing seals often means the cartridge/washer or valve seat still needs attention.
• A leak around the faucet base or handle may point to worn O-rings or a damaged cartridge.
• If parts are corroded, stuck, or the faucet body itself is damaged, replacing the faucet may be easier than rebuilding it.

If you tell me:

1. whether it has one handle or two,
2. where it leaks (from the spout, handle, or base), and
3. the faucet brand (if visible),

I can give you the exact repair steps.

If it’s a bathroom sink faucet that drips from the spout, it’s usually a worn cartridge, stem, washer, or O-ring. The repair is often straightforward.

What you’ll need

• Adjustable wrench or pliers
• Phillips/flat-head screwdriver
• Replacement cartridge, stem, washer, or O-ring
• Towel
• Small container for screws/parts
• Optional: silicone faucet grease

Step-by-step

1. Turn off the water. Close the hot and cold shutoff valves underneath the sink. If there aren't individual valves, shut off the home's main water supply. Open the faucet briefly to relieve pressure.
2. Plug the drain or cover it with a towel. This prevents tiny screws from disappearing down the drain.
3. Remove the handle. Look for a small screw, sometimes hidden beneath a decorative cap. Remove the screw and lift the handle off.
4. Remove the cartridge or stem. Depending on the faucet, you'll typically loosen a retaining/packing nut and pull the cartridge or stem straight out.
5. Inspect the old part. Look for cracked washers, damaged O-rings, corrosion, or a worn cartridge. If you're unsure what replacement you need, take the old cartridge/stem to a hardware or plumbing store so you can match it exactly.
6. Install the replacement. Clean the inside of the faucet, replace any damaged O-rings, and install the new cartridge/stem in the same orientation as the old one. Don't force it.
7. Reassemble and test. Put the retaining nut and handle back on, turn the water supply on slowly, and check both the faucet and the connections underneath for leaks.

If the leak is somewhere else

• Water leaking around the handle: often an O-ring, cartridge, or loose retaining nut.
• Water leaking from underneath the sink: likely a supply-line or faucet-base connection rather than the faucet cartridge.
• Two-handle faucet that drips: the washer/stem on the leaking side is a common culprit.
• Shower/tub faucet: the repair is different; it usually involves a wall-mounted cartridge or stem.

If you tell me whether it's a one-handle or two-handle faucet and exactly where the water is coming from, I can walk you through the specific repair.

To fix a leaky bathroom faucet, you will need to shut off the water supply under the sink, remove the handle , and replace worn internal parts like the cartridge, washer, or O-rings . Most leaks are caused by degraded rubber seals or cartridges that can be easily replaced in about 15 to 30 minutes with basic tools.

1:45 How to Fix a Leaky Faucet | The Home Depot 1.7M views  · 8 years ago YouTube · The Home Depot

Tools and Materials Needed

• Adjustable wrench or channel-lock pliers
• Allen wrench (hex key, usually 3/32" or 1/16")
• Flathead and Phillips-head screwdrivers
• Needle-nose pliers
• Replacement parts (specific cartridge, washer, or O-ring kit matched to your faucet brand)
• Plumber's silicone grease
• Rags or a small towel

Step-by-Step Repair Guide

1. Shut off the water supply: Locate the shut-off valves under the sink and turn them clockwise to close both the hot and cold lines. Open the faucet handles to drain any remaining water from the pipes.
2. Plug the drain: Place a cloth or stopper over the sink drain so you do not accidentally drop small screws, nuts, or springs down the pipe.
3. Remove the handle: Look for a set screw on the side or back of the handle (use your Allen wrench) or a decorative cap on top that pops off to reveal a Phillips screw. Loosen the screw and pull the handle straight up and off.
4. Access the cartridge or stem: Remove any decorative sleeves or retaining nuts using an adjustable wrench or pliers. Take a photo of the orientation of the internal parts before removing them.
5. Inspect and replace faulty parts: Pull out the old cartridge or check down in the housing for small rubber seats and springs.
   • If water leaks from the spout tip, it is usually a worn washer, seat, or spring.
   • If water leaks around the base of the handle, replace the O-rings or the entire cartridge. Take your old parts to the hardware store to ensure an exact match.
6. Reassemble the faucet: Insert the new springs and rubber seals (making sure the wider part of the spring faces down), apply a light coat of plumber's grease to new rubber components, and position the new cartridge correctly. Screw the retaining nut back on snugly—do not overtighten.
7. Test the repair: Reattach the handle and tighten its screw. Slowly turn the water supply valves back on, and let the water run for a minute to clear out trapped air and debris before checking for leaks.

If you want to make sure you buy the correct replacement components, tell me the brand name of your faucet (such as Delta, Moen, or Kohler) or whether it is a single-handle or double-handle model.

A leaky bathroom faucet is usually a straightforward DIY repair. The most common culprit is a worn cartridge, washer, or O-ring.

First, identify where it leaks

• Drips from the spout even when the faucet is off: usually a worn cartridge/washer.
• Water leaks around the handle: often an O-ring or cartridge.
• Water leaks around the base of the spout: usually a worn seal/O-ring.
• Water sprays or leaks from the aerator: the aerator may be loose, cross-threaded, or have a damaged/missing gasket.

For the typical bathroom sink faucet

You'll need: screwdriver, adjustable wrench, towel, and the correct replacement cartridge or washers/O-rings. Plumber's grease is useful for new rubber seals.

1. Turn off the water. Close the hot and cold shutoff valves underneath the sink. Open the faucet briefly to release pressure.
2. Plug the drain or put a towel over it so you don't lose screws or small parts.
3. Remove the handle. Look for a decorative cap hiding the screw, or a small set screw on the side.
4. Remove the cartridge/stem. The exact retaining nut or clip depends on the faucet.
5. Replace the worn part. For most modern single-handle faucets, replacing the entire cartridge is easiest. For older two-handle compression faucets, a worn rubber washer may be all you need.
6. Reassemble everything in the same orientation. Don't overtighten.
7. Turn the water back on slowly and check around the spout, handle, and base for leaks.

Tip: Take the old cartridge with you when buying the replacement, or look up your faucet's brand and model number. Cartridges aren't universal.

If you tell me whether your faucet has one handle or two, and exactly where the water is leaking, I can walk you through the specific repair step by step.

Fixing a leaky bathroom faucet is a straightforward DIY project that usually takes under an hour. Most leaks are caused by a worn-out washer, O-ring, or cartridge.

Tools and Materials Needed

• Adjustable wrench
• Phillips and flathead screwdrivers
• Replacement parts (O-rings, washers, or a new valve cartridge matching your brand)
• Plumber's tape (thread seal tape)
• Clean rag or small towel
• Flashlight
• Basin wrench (optional, helpful for tight spaces under the sink)

Step-by-Step Instructions

1. Shut off the water supply
   Locate the shut-off valves under the sink (one for hot, one for cold) and turn them clockwise until fully closed. If there are no under-sink valves, turn off the main water supply to your home.
2. Drain the remaining water
   Turn the faucet handles on to release any trapped water and pressure in the lines. Place a small towel or rag over the drain so you don't accidentally drop any tiny screws or parts down the pipe.
3. Remove the faucet handle
   Look for a decorative cap or button on the handle (often labeled 'H' and 'C' or with a brand logo). Pry it off gently with a flathead screwdriver or fingernail to expose the handle screw. Unscrew the handle and lift it off the valve stem.
4. Access and inspect the internal parts
   Depending on your faucet type (compression, cartridge, ball, or ceramic disk), remove the retaining nut or clip holding the internal mechanism. Pull out the stem, cartridge, or ball assembly. Inspect the rubber O-rings, washers, and seals for cracks, stiffness, or wear.
5. Replace damaged components
   Take the old parts to a hardware store to ensure an exact match, or replace the entire cartridge if it is worn out. Wrap a small amount of plumber's tape clockwise around any threaded connections before reassembling.
6. Reassemble the faucet
   Put the clean or new parts back into the faucet body in the exact reverse order you took them apart. Secure the retaining nut, attach the handle, and tighten the handle screw. Replace the decorative cap.
7. Test for leaks
   Ensure the faucet handle is in the closed position, then slowly turn the under-sink water supply valves back on. Turn on the faucet to flush out any trapped air and check for leaks around the base and spout.

If you'd like, let me know:

• What brand or type of faucet you have (single-handle, double-handle, or a specific brand like Moen or Delta)
• Where the leak is coming from (the spout, the base of the handle, or underneath the sink)

I can give you more targeted troubleshooting advice for your specific setup.

A leaky bathroom faucet is usually caused by a worn washer, O-ring, or cartridge inside the handle. The repair is often a small parts replacement rather than replacing the whole faucet.

What you’ll need

• Adjustable wrench or pliers
• Screwdrivers (Phillips and flathead)
• Towel or rag
• Replacement cartridge, washer, or O-ring (depends on faucet type)
• Plumber’s grease (helpful for O-rings/cartridges)

   • Look under the sink for the hot and cold shutoff valves.
   • Turn them clockwise until closed.
   • Open the faucet briefly to release pressure.

2. Identify where it’s leaking

   • Dripping from the spout: usually a worn cartridge, washer, or valve seal.
   • Water leaking around the handle: often an O-ring or cartridge issue.
   • Water leaking from the faucet base: often a worn O-ring or seal.

3. Remove the handle

   • Pry off the decorative cap if there is one.
   • Remove the screw (often hidden under the cap).
   • Pull the handle off.

4. Remove the internal part

   • For many single-handle faucets, remove the retaining nut or clip and pull out the cartridge.
   • For two-handle faucets, remove the stem and inspect the rubber washer.

5. Replace the worn part

   • Match the old cartridge/washer/O-ring exactly when buying the replacement.
   • Install the new part in the same orientation as the old one.
   • Lightly coat O-rings with plumber’s grease if appropriate.

Step-by-Step Repair Guide

1. Shut off the water supply : Turn off the hot and cold water shut-off valves located directly underneath your sink. Open the faucet handles to drain any remaining water and relieve pressure.
2. Plug the drain : Cover the sink drain hole with a rag or stopper so you do not accidentally drop small screws or parts down the pipe.
3. Remove the handle : Look for a tiny set screw on the side or back of the faucet handle, or under a small decorative snap-on cap on top. Use an Allen wrench or a flathead screwdriver to loosen the screw, then pull the handle straight up and off.
4. Access the internal cartridge or stem : Remove any decorative sleeves or retaining nuts using an adjustable wrench or channel locks. Pull the old cartridge, stem, or ball assembly straight up out of the housing.
5. Inspect and replace small seals or the cartridge : Look inside the valve body for tiny rubber seats and springs using needle-nose pliers. If they are torn, warped, or calcified, swap them out along with the cartridge or washers. Take the old parts to a hardware store to ensure an exact brand match.
6. Reassemble the faucet : Apply a thin layer of waterproof silicone plumber's grease to the new rubber components and cartridge to reduce friction. Put the parts back in the exact same orientation, hand-tighten the retaining nut, and snug it gently with a wrench (do not overtighten).
7. Test the repair : Reattach the handle and tighten its set screw. Slowly turn the water supply valves back on underneath the sink and let the water run for a minute to clear out any trapped air or debris before checking for leaks.

If you can tell me the brand name of your faucet (like Delta, Moen, or Kohler) or whether it is a single-handle vs. two-handle model, I can give you the exact replacement part names you'll need.

Absolutely. Most bathroom faucet leaks are DIY-friendly. The key is figuring out where the water is coming from before taking anything apart.

1. Turn off the water

Look underneath the sink for the two small shutoff valves—one for hot and one for cold. Turn them clockwise. Open the faucet to release pressure. The EPA also recommends shutting off the water before repairing a faucet.

Put a towel in the cabinet and close the drain so you don't lose small parts.

2. Identify the type of leak

• Water dripping from the spout when the faucet is off: usually a worn cartridge, valve, or rubber washer.
• Water leaking around the handle: often a worn O-ring or cartridge seal.
• Water leaking underneath the sink: check the supply-line connections and the faucet's mounting/connection points.

3. If it's dripping from the spout

Single-handle faucet:

1. Remove the decorative cap or set screw on the handle.
2. Remove the handle.
3. Take out the retaining nut/clip.
4. Pull out the cartridge.
5. Replace it with the exact matching cartridge for your faucet model.
6. Reassemble and slowly turn the water back on.

Two-handle faucet:
Remove the leaking handle and valve/stem. Older compression-style faucets commonly have a small rubber washer that wears out; replacing the washer can stop the drip. Worn washers and gaskets are a common cause of faucet leaks.

4. Test it

Turn the shutoff valves back on slowly and run the faucet. Check both the spout and underneath the sink for leaks.

Don't force anything. If the cartridge is seized, the shutoff valve won't close, or you discover corrosion/cracked plumbing, it's safer to stop rather than risk breaking the plumbing.

If you send me a photo of your faucet (including the handles and the area underneath the sink), I can tell you what type it is and walk you through exactly which part to remove.
