A dripping showerhead usually means mineral buildup is holding the seal open, or the washer or O-ring inside the head is worn. Start by checking the showerhead itself before you assume the valve is bad. The safest first fix is a clean-and-reseat job you can reverse if it doesn’t help.
What the drip is telling you
A brief drip right after you turn the shower off can be normal if water is just draining out of the arm and showerhead.
A steady drip that keeps going usually points to a seal that isn’t closing cleanly. In many cases, the first thing to check is scale or grit on the showerhead inlet, the internal screen, or the washer or O-ring. If the drip changes when you wiggle the head, or it starts and stops on its own, that also points to a seal problem rather than trapped water alone.
Before you start
This fix is for a showerhead that’s dripping after the shower is off, not for a leak that’s clearly coming from the tub spout, wall valve, or another fixture nearby.
Have a cloth or towel ready to protect the finish, plus a soft brush or toothbrush for cleaning. If you plan to soak parts, check the showerhead manufacturer’s instructions first, because some finishes and internal parts don’t tolerate every cleaner.
Stop and call a plumber, or switch to the valve manufacturer’s instructions, if the drip appears to come from inside the wall, the shower handle won’t shut off cleanly, or the showerhead body looks cracked or badly corroded.
Check whether the showerhead is actually the problem
Turn the shower on briefly, then shut it off and watch where the water comes from.
If water is still coming out of the showerhead face, the head or its seal is the likely problem. If the showerhead stops but water drips from the tub spout, the valve may be the issue instead. If you have a hand shower or another fixture on the same wall, check that it isn’t the source of the leak.
For a simple isolation check, wait a few minutes after shutting off the shower. A head that drips briefly and then stops is usually just draining. A head that keeps weeping steadily, or resumes dripping after it seemed to stop, is more likely to have buildup or a worn seal.
The easiest fix to try first
Use the reversible fix first: clean the showerhead and inspect the sealing parts before replacing anything.
- Turn off the shower and let the water pressure settle.
- Unscrew the showerhead from the arm by hand if you can. If it’s stuck, protect the finish with a cloth or towel before using pliers gently.
- Look inside the showerhead inlet for a rubber washer or O-ring, and for any screen or insert that catches debris.
- Rinse out loose grit. If you see white or chalky buildup, clean that mineral scale off the inlet, threads, and face openings. A toothbrush or soft brush helps. If the part is removable, follow the manufacturer’s instructions for soaking or cleaning it.
- Inspect the washer or O-ring. If it’s flattened, cracked, missing, or nicked, that’s a strong sign it needs replacement.
- Reassemble the head without forcing it. Tighten it snugly, not hard. Over-tightening can deform the washer or damage the threads, which can make the drip worse.
If the dripping was caused by mineral buildup holding the seal open, cleaning often fixes it right away. If the washer or O-ring was the problem, swapping that part usually restores the seal.
How to tell if the leak is coming from the valve instead
If the showerhead is clean, the washer or O-ring looks good, and the drip still continues, the problem may be inside the wall at the shutoff valve. A worn cartridge, valve seat, or stem can let water sneak past even when the handle is off.
A common clue is that the showerhead still drips after you’ve removed and cleaned it, or after you’ve replaced the head and the leak behavior does not change. Another clue is that the leak seems to come and go with slight handle movement, or that the shower never fully shuts off cleanly.
At that point, the showerhead itself is probably not the whole problem. The exact repair depends on the valve brand and model, so check the manufacturer’s instructions for that valve before buying parts or taking the assembly apart.
Test it after you put it back on
Once the showerhead is reinstalled, run a short test. Turn the shower on for a minute, then shut it off and watch the head closely.
You want to see either no drip at all or a brief drain-down that stops quickly. Then wait a few more minutes and check again. A successful fix means the showerhead stays dry or only releases the last bit of trapped water, not a continued drip.
If the drip slows but does not stop, the seal may still be dirty, the washer may be mismatched, or the leak may actually be coming from the valve. If the drip is unchanged, stop and go back to diagnosis instead of tightening the head harder.
How to keep it from dripping again
If your water is hard, occasional descaling can help keep mineral buildup from holding the seal open again.
Don’t overtighten the showerhead when you reinstall it. Snug is enough in most cases. Extra force can flatten the washer, stress plastic parts, and make future removal harder.
If the head starts dripping again after a cleaning, check it early instead of waiting for a bigger leak. Catching scale or wear at the start is easier than dealing with a stripped fitting or a valve problem later.
Frequently Asked Questions
Should I replace the showerhead or the washer first?
Try cleaning the showerhead and checking the washer or O-ring first if the head is otherwise in good shape. Replace the whole head if the body is cracked, heavily corroded, or the internal parts are damaged or non-serviceable.
Why does my showerhead drip only for a minute after I shut it off?
That is usually trapped water draining out of the head and arm. If it keeps dripping steadily after that, treat it as a leak rather than normal drain-down.
How do I know if the valve is bad?
If the showerhead is clean and sound but the leak continues, or if the shower never fully shuts off, the valve or cartridge may be letting water pass. Check the valve manufacturer’s instructions, because the repair depends on the exact model.
