How to Fix a Leaking Showerhead

A showerhead that drips between showers or leaks where it joins the wall is one of those small problems that quietly wastes water and gets more irritating by the day. Almost always it comes down to one of three things — a worn rubber washer, a loose or unsealed thread, or a build-up of limescale — and all three are quick, cheap fixes you can do with basic tools. This guide walks through finding the source of the leak and fixing each type.

Start by working out exactly where the water is coming from, because that points straight to the fix.

Find Where It’s Leaking

Watch the showerhead closely. If water drips from the connection where the head screws onto the shower arm, the thread seal has failed or worked loose. If water drips from the face of the head a few seconds after you turn the shower off, that’s usually just residual water draining out and is completely normal. But if it keeps dripping from the face minute after minute, the cause is a worn washer inside the head or a faulty shower valve further back. And if the spray is weak, uneven, or some nozzles are blocked, limescale is the culprit.

What You’ll Need

You’ll want an adjustable wrench or a pair of pliers (wrap the jaws in a cloth so you don’t scratch the finish), some PTFE thread seal tape, a few replacement rubber washers, white vinegar, and an old toothbrush. If the head is cracked or old, have a replacement showerhead ready too.

Fix 1: A Leak at the Connection

If water seeps from where the head meets the shower arm, the fix takes five minutes. Unscrew the showerhead from the arm by turning it counter-clockwise — use the cloth-wrapped wrench if it’s tight. Peel away the old thread tape from the arm’s threads and wipe them clean. Wrap fresh PTFE tape clockwise around the threads, four or five times, pressing it into the grooves. Screw the head back on hand-tight, then give it a gentle nudge with the wrench. The new tape fills the gaps in the threads and stops the leak.

Fix 2: A Drip From the Face of the Head

First confirm it’s a real leak and not just water draining out for a few seconds after you turn off — that’s normal. If it drips continuously, unscrew the head and look inside the connection for a small rubber washer or O-ring. If it’s cracked, flattened, or perished, replace it with a matching one. This cures most face drips. If the head still drips after a new washer, the problem is further back in the shower’s mixing valve or cartridge, which controls the water flow — a worn cartridge lets water creep through to the head, and replacing it is a bigger job.

Fix 3: Clear Limescale and Mineral Buildup

Hard water leaves chalky deposits that block nozzles and stop washers sealing properly. Fill a plastic bag with white vinegar, slip it over the showerhead so the head is submerged, and tie it in place with a rubber band. Leave it for an hour or two (overnight for heavy buildup), then remove it and scrub the nozzles with an old toothbrush. Run the shower to flush out loosened debris. Clearing scale often fixes both weak spray and a head that wouldn’t stop dripping.

Fix 4: Replace the Showerhead

If the head is cracked, corroded, or simply old, replacing it is cheap and easy. Unscrew the old one, clean and re-tape the shower arm threads with PTFE tape, and screw the new head on hand-tight plus a small turn with a wrench. Take the chance to choose a water-efficient model, which lowers both your water and heating bills.

How Much Does It Cost?

Thread tape and a pack of washers cost only a couple of dollars, and a new showerhead runs about $15 to $40. Compared with a plumber’s call-out, every fix here is firmly worth doing yourself.

When to Call a Professional

If the leak isn’t at the head but appears to come from inside the wall, or the drip continues after you’ve replaced the washer and cleaned everything — pointing to a failed mixing valve cartridge — it’s worth bringing in a plumber. Water appearing on the ceiling below an upstairs shower also needs prompt professional attention before it causes damage.

Frequently Asked Questions

Why does my showerhead drip after I turn it off?

A few seconds of dripping is just water left in the head draining out, which is normal. If it keeps dripping minute after minute, the cause is a worn washer inside the head or a faulty shower valve cartridge letting water through.

How do I remove limescale from a showerhead?

Tie a bag of white vinegar over the head so it’s fully submerged, leave it for an hour or two, then scrub the nozzles with an old toothbrush and rinse. For heavy buildup, leave it to soak overnight.

Do I need plumber’s tape on a showerhead?

Yes — wrapping PTFE thread tape around the shower arm’s threads seals the connection and is the most common fix for a leak where the head screws on. Use four or five clockwise wraps before refitting the head.

Why is my showerhead leaking where it connects to the wall?

The thread seal has failed or the head has worked loose. Unscrew the head, clean the threads, wrap fresh PTFE tape around them, and screw it back on snugly to stop the leak.

How do I stop a showerhead from dripping?

Identify where it leaks: reseal the threads with PTFE tape for a connection leak, replace the internal washer for a face drip, and clear limescale with a vinegar soak. If it persists, the shower valve cartridge likely needs replacing.
