Fast DIY Fix for a Dripping Showerhead (Tools You Probably Have)
Updated for 2026 to reflect current UK emergency call-out pricing and insurance changes.
A dripping showerhead isn’t just an annoyance keeping you awake at night—it can waste hundreds of gallons of hot water a month. Most showerhead leaks are incredibly simple to fix and rarely require an expensive call to a professional plumber.
Time Needed: 25 Minutes
- Adjustable wrench or pliers
- Rag or cloth (to prevent scratching chrome)
- White vinegar & old toothbrush
- Teflon tape (Plumber’s tape) & new rubber washer
Quick Diagnosis: Is it the Head or the Valve?
It’s important to understand where the problem actually lies:
- Leaking where the head meets the pipe: This is a failure of the rubber O-ring or Teflon tape connecting the showerhead to the wall pipe. Very easy DIY fix.
- Dripping constantly from the nozzles after it’s turned off: If water continues to leak hours after you’ve shut the handle off, the problem isn’t the showerhead itself—it’s a faulty cartridge in the hot/cold handle valve on the wall.
Step-by-Step Fix
Step 1: Turn Off the Water
Technically, if the shower handles are turned off, no water should flow to the showerhead. However, to be safe, turn off the mains water supply to the bathroom or the whole house, especially if you plan to disassemble the wall handles later.
Step 2: Remove the Showerhead
Wrap a rag around the nut connecting the showerhead to the wall pipe (the shower arm). This prevents your wrench from scratching the chrome finish. Use an adjustable wrench to turn the nut counterclockwise. Once loosened, unscrew the rest by hand.
Step 3: Clean Out the Hard Water Deposits
Look inside the threaded hole of the showerhead. You’ll likely see a crusty white or green buildup (limescale). Soak the showerhead in a bowl of warm white vinegar for 15 minutes, then scrub the threads and the inner filter screen with an old toothbrush.
Step 4: Replace the Washer and Apply Tape
Pry out the old rubber washer/O-ring from inside the showerhead fitting (it’s usually squashed and hardened) and push a new one in. Next, clean the threads on the wall pipe. Wrap fresh Teflon tape (plumber’s tape) around the threads of the wall pipe clockwise, doing about 3 full wraps.
Step 5: Reattach and Test
Screw the showerhead back onto the wall pipe by hand until tight, then give it a final quarter-turn with the rag and wrench. Turn the water supply back on and test for leaks.
When the Handle Valve is the Problem
If you clean and reattach the showerhead but it still drips constantly overnight, the internal cartridge inside the main shower handle is failing to shut the water off completely.
Replacing a shower cartridge requires removing the handle faceplate, pulling out the retaining clip, and swapping the specialized cartridge. While it’s a doable DIY, mistakes can cause water to leak behind the tile wall. If you are uncomfortable with this, check our guide on Shower Repair Costs to hire a pro.
Frequently Asked Questions
Why does my showerhead drip for 5 minutes after I turn it off?
This is perfectly normal. The shower pipe running up the wall remains full of water when you shut off the valve. Gravity slowly drains this residual water out of the showerhead over a few minutes. It is only a problem if it drips continuously all day.
Do I really need Teflon tape?
Yes. Metal-on-metal or plastic-on-metal threads do not create a perfectly watertight seal on their own. Plumber’s tape fills the microscopic gaps in the threads to prevent high-pressure water from weeping out.
