A shower head that drips after you turn the water off wastes water and can be a sign of a worn seal or limescale buildup rather than anything more serious. This guide covers how to diagnose and fix the most common causes.
How Do You Fix a Leaky Shower Head?
To fix a leaky shower head, unscrew it and check the rubber O-ring or washer for wear, clean or descale the connection and nozzle holes with vinegar, then reassemble with fresh plumber’s tape around the thread for a tight seal. Most leaks come from a worn seal or limescale buildup preventing a proper connection, rather than a fault with the shower itself.
What You Will Need
- An adjustable spanner or pliers, wrapped in a cloth to avoid scratching the fitting
- A replacement O-ring or washer, if needed
- Plumber’s PTFE tape
- White vinegar, for descaling
- A soft brush or old toothbrush
How to Fix a Leaky Shower Head: Step by Step
1. Identify Where the Leak Is Coming From
Check whether water drips from the connection where the hose meets the shower head, or from the nozzle holes themselves, since this affects which fix is needed.
2. Remove the Shower Head
Unscrew the shower head from the hose, using a cloth-wrapped spanner if it is stiff, to avoid scratching the finish.
3. Inspect the O-Ring or Washer
Check the small rubber seal inside the connection for cracks, flattening, or general wear. A worn seal is one of the most common causes of a leak at the connection point.
4. Descale the Shower Head
Soak the shower head in a bowl of white vinegar for at least an hour, or overnight for heavier limescale, then scrub gently with a soft brush or toothbrush to clear blocked nozzle holes, which can cause uneven spray or pressure that puts extra strain on seals.
5. Replace the Seal if Needed
If the O-ring or washer is visibly worn, replace it with a new one of the same size, available cheaply from most hardware shops.
6. Apply Fresh PTFE Tape
Wrap PTFE tape clockwise around the threaded connection two to three times before reattaching the shower head, which helps create a tighter, leak-resistant seal.
7. Reattach and Test
Screw the shower head back on firmly by hand, then test the water. If it still leaks at the connection, tighten slightly further with a cloth-wrapped spanner, taking care not to overtighten and crack the fitting.
When the Problem Is the Shower Valve, Not the Head
If water continues to drip from the shower valve itself, rather than the head, after the water is turned off, the issue is likely a worn valve cartridge or washer inside the mixer or wall unit, which is a separate and often more involved repair, sometimes better left to a plumber depending on your shower type.
If limescale is a recurring issue elsewhere in your bathroom too, our guide to removing limescale from taps and showerheads covers the same problem on other fixtures.
Frequently Asked Questions
Why does my shower head drip after I turn off the water?
A worn O-ring or washer at the connection, or limescale buildup preventing a proper seal, are the most common causes of a shower head continuing to drip after use.
How do I know if it is the shower head or the valve leaking?
If the leak comes from where the head connects to the hose, the head or its seal is usually the cause. If water drips from the valve or mixer unit itself, the issue lies further back in the system.
Can limescale cause a shower head to leak?
Yes. Limescale buildup inside the connection or around nozzle holes can prevent components from sealing properly, contributing to leaks and uneven water flow.
Do I need to replace the whole shower head to fix a leak?
Not usually. Most leaks are caused by a worn seal or limescale, both of which can be fixed by cleaning, descaling, or replacing a small rubber washer rather than the entire unit.
How often should I descale my shower head?
In hard water areas, descaling every one to two months helps maintain water pressure and reduces the chance of limescale-related leaks developing.
If a leak persists after cleaning and reseating the shower head, or appears to come from the valve itself, it may be worth consulting a plumber to assess the internal components.
