How to Fix a Leaking Shower Head
Dripping that carries on after the shower is shut off is usually not a shower head fault at all. The failed part normally sits in the wall mixer, and working out how to fix a leaking shower head starts with telling the two situations apart. This guide from our Auchenflower team covers the drips you can ignore, the faults you cannot, and the one swap Queensland law allows you to do yourself.

Everything inside the mixer belongs with a licensed plumber, and we mark exactly where that line sits.
Normal Drips Versus a Failing Seal
Some dripping after you shut the shower off is perfectly normal; a drip that goes for minutes or hours afterwards is not. Water held inside the head drains away briefly once use ends, and that trickle stops by itself. A drip that persists comes from the mixer, where a washer or cartridge no longer seals, and no attention given to the head will stop it.
Density is why the distinction matters here. Auchenflower carries about 4,890 residents on each square kilometre at 2025 area-level estimates, and many of those showers sit above a neighbour's ceiling in strata blocks. A slow drip in a unit bathroom rarely stays one household's problem for long.
Head, Joint or Mixer Behind the Wall
Three places produce nearly every dripping shower: the joint where the arm and head connect, the mixer hidden in the wall, and, on a bath-shower combination, the spout with its diverter. Each has its own signature.
The joint
water seeping there only while water is flowing suggests the fitting has worked loose or a perished seal at that connection.
The mixer
a drip with the taps shut points to the in-wall mixer, where the washer or the cartridge no longer seals.
The diverter
water creeping from the head while the bath fills, or running from the spout mid-shower, suggests a diverter past its best or a restricted spout rather than any fault in the head.
Scale is the odd one out. Mineral crust can block the spray holes and push water sideways through other parts of the head, which reads like a leak but is really a spray pattern gone wrong.
The mixers behind this suburb's bathroom walls also span every building age at once, because units have gone up over decades in place of the timber houses. A dripping shower in a block near the station may sit on plumbing decades older than the tiles around it.
Still Dripping After a Repair Attempt
A drip that persists after a replacement washer or cartridge has gone in usually means the problem sits below the part: the seat the washer presses against, or the body the cartridge seals within. A washer presses on a machined seat, and a cartridge seals inside the body of the mixer. If either surface is worn or damaged, the fresh part still cannot seal, and water keeps getting through.
A licensed plumber checks the mixer and quotes the repair at that point. The QBCC classes work on a fitting inside the mixer as minor work: a licensee does it, but no permit applies and no Form 4 is filed. Trying a different part in the same worn body rarely ends any differently.
The Shower Head Swap the Law Allows
Yes, Queensland law lets you swap a shower head yourself. The QBCC lists that job as unregulated work, open to anyone who has the needed knowledge and skill.
No approval from the QBCC or your local government is required, and the work does not have to be reported. The finished job still has to meet the minimum standards in the legislation and the codes.
The freedom ends at the wall. A cartridge or valve inside the mixer is a job for a licensed plumber, because the QBCC's list of unregulated work names the shower head and stops there.
Choose a replacement head registered under the Water Efficiency Labelling and Standards (WELS) scheme. A shower head sold in or to Australia shows the star rating and its water-use details wherever it is listed for sale, online included.
When to Call a Plumber
Call a plumber when the drip continues with the taps shut, or when a new part has not stopped it. Water appearing where it should not, such as staining on a wall below the bathroom, also earns a call.
A drip over the ceiling of the unit below, in one of the strata blocks near the station, deserves a call the same week, because water travels through slabs to the unit underneath. The shower repairs guide goes deeper on mixers, diverters and in-wall faults, and that is where the washer question ends and the licensed work begins.
Shower Head Questions From Auchenflower
Call (07) 3523 6417Do I need approval to change a shower head in Queensland?
No, approval is not needed. A shower head swap is unregulated work in Queensland, so neither the QBCC nor your local council needs to sign off, and nothing has to be reported. The finished job still has to meet the minimum standards.
Why does my shower still drip after a new cartridge?
Because the new part is not where the leak lives. The washer seats against a machined surface, and the cartridge closes inside the mixer body, so a worn seat or a damaged body lets water past a fresh part. A licensed plumber examines the mixer, then quotes the repair.
Who fixes a dripping shower head in an Auchenflower rental?
The renter tells the property manager or owner as soon as possible, and Queensland tenancy law puts the duty of keeping the rental in good repair on the owner or manager. Changing a shower head is among the very minor jobs a rental allows without a licensee; the mixer is not.
How much does it cost to fix a leaking shower head in Auchenflower?
The price hinges on two things: whether the head or the in-wall mixer is at fault, and how easily the plumber can reach the mixer. You get a fixed quote before any work starts, so the figure is settled before tools come out.
