A showerhead that drips after you turn it off wastes roughly 5 gallons of water a day — over 1,800 gallons a year, according to the EPA. The fix is almost always a worn-out rubber washer or a clogged connection, and you can handle it in about 10 minutes with one adjustable wrench and a roll of Teflon tape. No plumber, no special parts run required.
Figure Out What Kind of Drip You Have
Before you grab a wrench, let the showerhead drip for a minute and watch where the water comes from. If it drips from the showerhead face after the faucet is off, the internal washer or cartridge seal is the likely culprit. If water seeps from the connection between the showerhead and the pipe (the threaded arm coming out of the wall), the thread seal has failed. That distinction matters because the fix is slightly different for each. Most drips fall into the first category — a degraded rubber washer inside the showerhead swivel joint that costs less than a dollar to replace.
Remove the Showerhead the Right Way
Wrap a cloth or strip of painter’s tape around the connector nut to protect the finish, then grip it with an adjustable wrench. Turn counter-clockwise. If it hasn’t been removed in years, it may be locked by mineral deposits — a few drops of white vinegar on the threads and 5 minutes of patience usually breaks the bond. Once the head is off, you’ll see the rubber washer (a small O-ring or flat disc) sitting right inside the swivel ball. If it’s cracked, flattened, or gummy, that’s your leak. Pull it out with your fingers or a flathead screwdriver tip. Take it to any hardware store for a match — these washers come in standard sizes and typically cost under $1.
Clean the Threads and Re-Seal
While the head is off, look at the pipe threads coming out of the wall. Old, shredded Teflon tape or mineral buildup here is often a secondary leak source people miss. Peel off any remaining tape, then wipe the threads clean with a damp rag. Wrap fresh Teflon tape clockwise around the threads — three full wraps is the standard recommendation. Clockwise matters: it keeps the tape from unwinding when you screw the head back on. If you’ve ever had a showerhead that leaked from the wall joint even though you used tape, wrapping in the wrong direction is the most common reason.
If you’re mid-project and realize a part needs replacing, the running deals page is worth a 30-second look before you pay full price at the hardware store.
Reattach and Test
Thread the showerhead back onto the arm by hand first — finger-tight until it stops. Then snug it an additional quarter-turn with the wrench (cloth still in place). Don’t over-torque it; you’ll crack the fitting or strip the threads. Turn on the water full blast for 30 seconds, then shut it off. Watch the connection and the head for a full minute. No drip? Done. If the connection still weeps, back it off and add one more wrap of Teflon tape. If the face still drips, the issue is likely a worn valve cartridge inside the wall — that’s a slightly bigger job, but still doable for most homeowners. If you’ve tackled a running toilet before, the cartridge swap is about the same difficulty level.
Prevent the Next Drip
Mineral buildup accelerates washer wear. Once every 6 months, unscrew the showerhead and soak it in a bowl of white vinegar for 30 minutes — this dissolves calcium deposits in the spray holes and around the swivel. It takes less time than cleaning the shower itself and extends the life of the washer considerably. If you live in a hard-water area (above 120 ppm, which you can test with a $10 strip kit), the soak is worth doing quarterly.
Frequently Asked Questions
Can I fix a dripping showerhead without turning off the water supply?
You can remove and replace the showerhead itself without shutting off the main supply — just make sure the shower faucet is fully off. The threaded arm is downstream of the valve, so no water flows while the faucet handle is in the off position. If you need to replace a valve cartridge inside the wall, you will need to shut off the water supply to that bathroom first.
How do I know if the problem is the showerhead or the faucet valve?
Replace the washer and re-tape the threads first. If the showerhead still drips from the face after 24 hours, the valve cartridge inside the wall is not seating properly. Cartridge replacements run $8–$25 depending on brand and take about 30 minutes.
Does a dripping showerhead really waste that much water?
The EPA estimates that a showerhead dripping at 10 drips per minute wastes over 500 gallons per year. Faster drips — the kind you can hear from the next room — can exceed 2,000 gallons annually. Fixing it is one of the easiest water-saving repairs in any home.
