Question: How do I fix a leaky faucet in my bathroom?
Google AI Mode· Sep 27, 2026
Shut off the water supply by locating the shut-off valves under the sink and turning them clockwise. If there are no individual valves, turn off the main water supply to your home.
Plug the drain so you don't accidentally drop any tiny screws, washers, or parts down the pipe.
Remove the decorative handle cap (if applicable) using a flathead screwdriver or Allen wrench to loosen the handle screw and pull the handle off.
Expose the valve mechanism by removing the outer decorative sleeve or retaining nut, depending on whether you have a compression, cartridge, ball, or ceramic disk faucet.
Inspect the internal parts (O-rings, washers, or springs) for wear, cracks, or mineral buildup. Take the old parts to a hardware store to find exact replacements.
Clean the interior valve seat using a wire brush or vinegar to remove any mineral deposits that could cause a new seal to leak.
Reassemble the faucet in reverse order, making sure all washers and O-rings sit flush and the handle screw is tightened securely.
Turn the water supply back on slowly and let the faucet run for a minute to clear out any trapped air or debris.
If you can tell me the brand of your faucet or whether it's a single-handle vs. double-handle model, I can give you more specific instructions for your exact setup.

Fixing a leaky bathroom faucet is a straightforward DIY project. Most bathroom faucets are either single-handle (cartridge/ball) or double-handle (compression) types.
Here is a step-by-step guide to tackling the repair:
Shut off the water supply : Look under the sink for the hot and cold water shut-off valves. Turn them clockwise until tight. If you don't have under-sink valves, turn off your home's main water supply.
Block the drain : Put a stopper or a washcloth over the sink drain so you don’t accidentally drop a tiny screw or washer down the pipe.
Remove the handle cap and screw : Pry off the decorative hot/cold indicator cap on the faucet handle using a flathead screwdriver or knife. Unscrew the handle retaining screw underneath and pull the handle off.
Expose the internal valve : Remove any decorative sleeves or retaining nuts holding the inner mechanism in place. Use tongue-and-groove pliers or an adjustable wrench if needed, being careful not to scratch the finish.

If you mean a bathroom sink faucet, a leak is usually caused by a worn cartridge, stem, washer, or O-ring.
What you'll need
Adjustable wrench
Screwdriver or Allen key
Pliers
Replacement cartridge/washer/O-ring
Rag or towel
Optional: silicone/plumber's grease
Step-by-step
Shut off the water.
Close the hot and cold shutoff valves underneath the sink. Then open the faucet briefly to release pressure and drain remaining water.
For single-handle faucets, pull out the cartridge or ball assembly.
For double-handle compression faucets, unscrew the stem to access the rubber washer and O-ring at the base.
Inspect and replace components : Take the old part to a hardware store to ensure an exact match. Replace worn-out rubber washers, frayed O-rings, or a cracked plastic/brass cartridge. Coat new O-rings with plumber’s grease before installing.
Reassemble the faucet : Put everything back together in the reverse order of how you took it apart. Secure the handle and tighten the retaining nuts snugly, but don’t over-tighten or you risk cracking the plastic or metal parts.
Test the repair : Turn the under-sink water supply valves back on slowly. Let the water run for a minute to clear out any trapped air or debris, then check for leaks around the base and handle.

Step-by-Step Repair Guide
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 you don't have individual shut-off valves under the sink, turn off the main water supply to your house.
Drain the remaining water
Turn the faucet handle(s) to the "on" position to let any water left in the pipes drain out completely. (Pro tip: Put a rag over the drain hole so you don't accidentally drop any tiny screws or parts down the pipe!)
Remove the handle
Look for a decorative cap or button on the handle (often red/blue indicating hot/cold). Pry it off gently with a flathead screwdriver or fingernail.
Unscrew the hidden set screw underneath using a screwdriver or an allen wrench.
Pull the handle straight up and off to expose the inner mechanism.
Access the internal parts
For compression faucets (two handles): Unscrew the packing nut or retaining nut using your wrench, then pull out the stem assembly. Look at the rubber O-ring and washer at the base.
For cartridge/ball/disk faucets (single handle): Remove any retaining clips, sleeves, or nuts holding the cartridge or valve assembly in place. Pull the cartridge straight out.
Inspect and replace worn parts
Examine the rubber washers, O-rings, and seals. If they are cracked, frayed, or flattened, they are the culprits.
Take the old parts or the entire cartridge to a hardware store to ensure you buy the exact matching replacements.
Reassemble the faucet
Clean out any mineral buildup or debris inside the faucet housing using a brush and vinegar or water.
Install the new washer, O-rings, or cartridge. Apply a small amount of plumber's grease to O-rings to make assembly smoother and prevent future leaks.
Put the handle back on, tighten the set screw, and snap the decorative cap back into place.
Test for leaks
Turn the water supply back on slowly by turning the under-sink valves counterclockwise.
Turn on the faucet and let it run for a minute to clear out trapped air. Turn it off and check closely for any dripping or seeping around the base and handle.
If you'd like to narrow down the exact parts you need, tell me:
Is your faucet single-handle or double-handle?
Do you know the brand name (like Moen, Delta, Kohler)?
Adjustable wrench
Phillips or flat-head screwdriver
Replacement washer/O-ring or cartridge
Towel
Plumber's tape if needed
Step-by-step
Turn off the water.
Close the two shutoff valves underneath the sink. Open the faucet briefly to release pressure and drain remaining water.
Determine where it's leaking.
Dripping from the spout when the faucet is off: usually a worn cartridge or washer.
Water around the handle: often an O-ring, cartridge, or packing seal.
Water around the base: could be a cartridge/O-ring or debris around the faucet; it can also be water running down from a handle leak.
Water leaking underneath the sink: check the supply-line connections and the faucet's mounting/gasket area.
Remove the handle.
Look for a decorative cap hiding the screw. Pop it off carefully, remove the screw, and lift the handle away. Put a towel over the drain so you don't lose small parts.
Inspect the internal mechanism.
On an older two-handle compression faucet, replacing the rubber washer is often enough.
On many single-handle or newer faucets, you'll need to replace the cartridge. Take the old cartridge with you when buying the replacement so you can match it exactly.
Install the replacement part.
For a cartridge, note its orientation before removing it, then install the new one in the same orientation. Replace any retaining clip/nut and reinstall the handle.
Turn the water back on slowly and check the faucet, handle, and connections for leaks.
Don't force stuck parts. If the faucet is badly corroded, the shutoff valve won't close, or the leak is inside the wall, it's safer to stop and call a plumber.
If you tell me whether your faucet has one handle or two, and exactly where the water is leaking (spout, handle, base, or underneath the sink), I can walk you through the specific repair.
Remove the handle. Pop off the decorative cap if there is one, then remove the screw—often Phillips or Allen—and lift off the handle.
Identify the mechanism:
Two-handle faucet with a visible stem: usually a compression faucet. Replace the worn rubber washer at the end of the stem.
One-handle faucet or a two-handle faucet with a plastic cartridge: replace the cartridge or its O-rings.
Take the old part with you when buying a replacement, or use the faucet's brand/model number. Cartridges vary considerably by faucet.
Reassemble, turn the water back on slowly, and check for leaks.
If it's leaking from the handle rather than the spout
That often points to an O-ring, packing seal, or cartridge, rather than the washer that controls the water at the spout.
If you tell me whether your faucet has one handle or two, and exactly where the water is leaking (from the spout, around the handle, or around the base), I can give you the exact step-by-step repair.
To fix a leaky bathroom faucet, you generally need to replace the internal cartridge or the rubber seats and springs that have worn down over time . This standard repair can be completed without a plumber in about 20 to 30 minutes using basic household tools.
Here is a comprehensive visual walkthrough demonstrating exactly how to disassemble the handle and swap out the internal components:
🛠️ Tools and Materials Needed
Adjustable wrench or channel-lock pliers
Phillips head and flathead screwdrivers
Allen (hex) wrench (depending on your faucet style)
Replacement cartridge or faucet repair kit
Plumber's grease (optional, for lubrication)
📋 Step-by-Step Repair Guide
Step 1: Turn Off the Water Supply
Locate the shut-off valves under your bathroom sink.
Turn both the hot and cold knobs clockwise until they are fully closed.
Open the faucet handles completely to drain out any residual water and release the pressure.
Tip: Plug the sink drain with a rag so you don’t accidentally lose any small screws down the pipe
Step 2: Identify the Leak (For Double-Handle Faucets)
If you have separate hot and cold handles, turn off only one supply valve at a time under the sink.
If the dripping stops when the cold valve is off, the cold side is leaking. If it keeps dripping, the hot side needs to be repaired.
Step 3: Remove the Faucet Handle
Remove the decorative cap on top of or behind the handle using a small flathead screwdriver.
Use your screwdriver or Allen wrench to loosen the hidden set screw underneath.
Pull the handle straight up and off.
Step 4: Remove the Retaining Nut and Old Cartridge
Use an adjustable wrench to loosen and unscrew the retaining nut (or bonnet nut) holding the cartridge in place.
Pull the old cartridge straight up out of the faucet body. You may need pliers if it is stuck.
Look inside the valve house. If your faucet uses small rubber seals and springs at the very bottom (common in Delta models), pry them out with a small screwdriver.
Step 5: Get the Right Replacement Parts
Faucet models vary significantly. The easiest way to get the exact replacement is to take your old cartridge and seals to a local hardware store like The Home Depot to match them perfectly.
Step 6: Install the New Components & Reassemble
If your faucet uses them, drop the new springs and rubber seats into the bottom holes first.
Coat the new cartridge O-rings with a thin layer of waterproof silicone plumber's grease.
Insert the new cartridge , aligning any built-in plastic tabs with the notches inside the faucet body.
Thread the retaining nut back on by hand, then tighten it gently with your wrench. Do not overtighten , as this can crack the plastic or strip the threads.
Reattach the handle, tighten the set screw, and pop the decorative cap back on.
Step 7: Flush and Test
Turn the water supply valves under the sink back on slowly.
Turn on the faucet to let the water run for a minute to flush out any trapped air or debris.
Turn the faucet off and check thoroughly for any remaining leaks around the handle or spout.
To help narrow down the exact parts you might need, could you tell me:

To help narrow down the exact parts you might need, could you tell me:
What brand is the faucet (e.g., Moen, Delta, Kohler)?
Is it a single-handle faucet or a two-handle setup?
Plug the drain.
Put in the sink stopper or cover the drain with a towel so you don't lose a screw or small part.
Remove the handle.
Look for a decorative cap or small Allen screw. Remove it, then pull the handle off.
Identify the leaking part.
Single-handle faucet: usually has a cartridge; a worn cartridge or O-ring is a common culprit.
Two-handle faucet: each handle typically has its own cartridge or compression stem. If only the hot side drips, you generally repair that side.
Remove the cartridge/stem.
Remove the retaining nut or clip, then pull the cartridge/stem straight out. Take note of its orientation. If it's stuck, don't force it excessively—some cartridges require a specific removal tool.
Replace the part.
The safest approach is to take the old cartridge/stem to a hardware store and match it exactly, since faucet parts vary considerably by manufacturer and model. Replace damaged O-rings as well.
Reassemble and test.
Put everything back in the same orientation, reinstall the handle, slowly turn the shutoff valves back on, and check both the faucet and the connections underneath for leaks.
One important distinction: if water is leaking from underneath the sink or around the faucet base, rather than dripping from the spout, the problem may be a loose supply connection or worn faucet-base seal rather than the cartridge.
If you tell me where exactly the water is coming from (spout, around the handle, base of faucet, or underneath the sink) and whether it's one handle or two, I can tell you exactly what to replace.
