A shower head that keeps dripping after you turn off the water can waste water, leave mineral stains, and make an otherwise peaceful bathroom surprisingly annoying. The good news is that the fix is often straightforward—but the drip may be coming from the shower valve, not the shower head itself. Start by working out which part is causing it, then follow the right repair steps so you don’t replace a perfectly good shower head for no reason.

First, find out where the drip is coming from
Watch what happens after you turn the shower off. A few drops that stop within a few minutes may simply be water draining from the shower head or arm. That’s usually normal, especially with large rain-style heads that hold more water.
A steady drip that continues for a long time—or starts again after the water has stopped—points to a problem. The most common cause is a worn cartridge, washer, or seal inside the shower valve. The valve controls the flow of water, so even a small gap inside it can let water creep through to the shower head.
There are a few clues that can help you narrow it down:
- Dripping stops after a short time: It may be leftover water draining from the shower head.
- Dripping continues for an hour or more: The valve cartridge or an internal seal may be worn.
- Spray comes from around the shower head connection: The washer or the threaded connection may need attention.
- Water leaks around the handle: The valve stem or handle seals may be damaged.
- The shower runs hot or cold unexpectedly: The cartridge may be damaged, incorrectly fitted, or affected by debris.
If you’re unsure, dry the shower head and the area around the handle with a towel, then check again after the water is off. Finding the exact source before taking anything apart can save you time and money.
What you’ll need
Most basic repairs call for a few common tools. The exact items depend on your shower model, so check the manufacturer’s instructions if you can find them.
- Adjustable wrench or strap wrench
- Screwdriver or hex key, depending on the handle
- Soft cloth or towel to protect the finish
- Replacement shower-head washer or valve cartridge, if needed
- White vinegar for mineral buildup
- Silicone-based plumbing grease for compatible seals
- Small container or plug to keep screws from falling into the drain
Take a photo of each part as you remove it. That simple habit makes it much easier to put everything back in the right order.
How to fix a dripping shower head in five steps
Step 1: Turn off the water supply
Before you remove the shower head or open the valve, shut off the water. Some showers have small service stops behind the trim plate or nearby access panel. If yours doesn’t, you may need to turn off the home’s main water supply.
Once the water is off, open the shower handle briefly. This releases pressure in the pipe and lets any remaining water drain. Keep a towel nearby, and cover the drain so a small screw or clip can’t disappear down it.
Don’t rely on turning the shower handle to the “off” position as a substitute for shutting off the supply. If the valve is the part that’s leaking, water may still reach the area while you’re working.
Step 2: Check and clean the shower head
If the leak appears to come from the joint where the shower head meets the shower arm, unscrew the head by turning it counterclockwise. Use a strap wrench if it’s tight. If you use an adjustable wrench, wrap the jaws with a cloth to help protect the finish from scratches.
Look inside the connection for a small rubber washer. A washer that’s flattened, cracked, or missing can allow water to leak around the joint. Replace it with one that matches the old washer in size and thickness. A random washer that almost fits may still leak or restrict water flow.
While the head is off, check the nozzles and inlet for mineral buildup. Soaking a removable shower head in white vinegar can loosen deposits. Follow the maker’s cleaning advice, particularly if the head has a special coating or delicate finish. Don’t soak a finished or electronic shower head unless its instructions say that it’s safe.
Rinse the head thoroughly before putting it back. If the connection uses a washer, that washer usually makes the seal; thread tape is not always needed. If the manufacturer recommends thread-seal tape, wrap it neatly around the shower-arm threads in the direction the head tightens. Avoid adding tape over the washer or using so much that the head won’t thread on properly.
Step 3: Test the connection
Reattach the shower head by hand, then tighten it gently with a strap wrench if needed. It should feel secure without being forced. Overtightening can damage the threads, crack a plastic fitting, or make the next repair harder.
Turn the water back on and run the shower briefly. Check the joint where the shower head meets the arm. If water sprays or drips from that connection, shut off the supply again and inspect the washer, threads, and fit. If the connection stays dry but water still drips from the nozzles after the valve is off, the shower valve is the more likely cause.
Step 4: Inspect and replace the shower valve cartridge or washer
Most modern single-handle showers use a cartridge. Older or two-handle showers may use separate stems and rubber washers. These parts open and close the path water takes through the valve. Over time, seals wear down, and mineral deposits can prevent the valve from closing fully.
To reach the internal part, remove the handle and trim plate. Handles are often held by a screw hidden under a cap, but the design varies. Take your time and avoid prying hard against tile or finished metal. If the handle won’t come off, check the product instructions rather than forcing it.
Before pulling out a cartridge, confirm that the water supply is off. Some valves have a retaining clip or nut that holds the cartridge in place. Note its position and orientation, then remove it carefully. Bring the old cartridge to a plumbing-supply shop or use the shower’s brand and model information to find an exact match. Cartridges that look similar can differ in length, shape, or port arrangement.
Fit the replacement according to the manufacturer’s instructions. The alignment matters: installing a cartridge upside down or in the wrong position can cause reversed hot and cold water or prevent the valve from shutting off properly. Use only a small amount of silicone-based plumbing grease where the instructions call for it. Petroleum jelly and other petroleum-based products can damage some rubber seals.
If your shower uses a washer-style valve, inspect the washer and valve seat. A damaged washer can often be replaced, but a badly worn seat may also need attention. This repair can involve more judgment and the right replacement parts, so consider calling a plumber if the seat is pitted or difficult to remove.
Step 5: Reassemble and test for leaks
Put the handle and trim back in place, making sure the cartridge clips and screws are secure. Restore the water supply slowly. Test the shower with the handle in both hot and cold positions, then turn it off and watch the shower head.
A small amount of water may drain from the head after shutoff. Give it a little time. If a steady drip continues, or if water leaks from behind the handle or trim, turn the supply off again and check the installation. A cartridge that isn’t fully seated, a misplaced seal, or an incorrect replacement part can all cause a new leak.
Common causes and the right first fix
| What you notice | Likely cause | First thing to try |
|---|---|---|
| Water drips briefly, then stops | Water draining from the shower head or arm | Wait and see whether it stops; this may not need repair |
| Water keeps dripping from the nozzles | Worn cartridge, stem, or internal seal | Identify the valve type and check its cartridge or washer |
| Water leaks at the shower-head connection | Worn washer, loose connection, or damaged threads | Remove the head and inspect the washer and threads |
| Water leaks around the handle | Worn valve seal or stem packing | Inspect the valve parts; replace the damaged seal or get help |
| Flow is uneven or the head’s nozzles spray oddly | Mineral deposits or debris | Clean the head according to its care instructions |
When to call a plumber
Replacing a shower head washer is usually a manageable DIY job. Valve repairs can be more complicated, especially when the shutoff is hard to reach or the cartridge is stuck. Call a licensed plumber if you can’t stop the water, the valve is corroded, the trim or pipework moves when you turn it, or the leak seems to be coming from inside the wall.
It’s also sensible to get professional help if you’ve installed the correct cartridge but the shower still leaks. The valve body, seat, or another part of the plumbing may be damaged. Forcing a stuck cartridge or turning a corroded fitting too hard can turn a small repair into a larger one.

Frequently Asked Questions
Is a dripping shower head always a sign of a broken valve?
No. A few drops that stop after a short time may be leftover water draining from the head. If the drip continues for a long time, a worn cartridge, washer, or seal is more likely.
Should I use plumber’s tape on a shower head?
Use it only if the shower-head instructions call for it. A washer often creates the seal at the connection, and tape won’t fix a damaged washer. If tape is recommended, apply it to the shower-arm threads without covering the washer.
Can I clean a dripping shower head with vinegar?
Vinegar can help remove mineral deposits from many shower heads, but it may not fix a leak caused by a faulty valve. Check the manufacturer’s cleaning advice first, especially for special finishes or electronic models.
How do I know which replacement cartridge to buy?
Use the shower valve’s brand and model number if available. You can also compare the old cartridge with a replacement at a plumbing-supply shop. Don’t assume that a cartridge will fit just because it looks similar.
Conclusion
Start by checking whether the drip is only leftover water or a continuing leak. Then inspect the shower-head connection and washer before moving on to the valve cartridge or internal seals. Match replacement parts carefully, shut off the water before opening the valve, and don’t force fittings that resist removal. If the leak is coming from inside the wall or the valve repair feels beyond your comfort level, a plumber can help prevent a small drip from becoming a much bigger problem.
