Signs You Need a Shower Repair

A leaking shower isn’t always obvious. Sometimes, the signs are subtle but catching them early can save you from expensive repairs. Look out for:

✔ Water stains or peeling paint on walls and ceilings near the bathroom
✔ Damp or musty smells indicating hidden water leaks
✔ Loose or missing grout and tiles around the shower area
✔ Pooling water around the base of the shower
✔ Increased water bills, suggesting hidden leaks

If you’ve noticed any of these issues, it’s time to call in professional shower plumbers. At O’Shea Plumbing, we accurately diagnose the problem and provide effective shower repair services to prevent further damage.

What Causes a Leaking Shower?

Shower leaks come from four different places, and they need four different fixes. That's the part that gets missed.

Behind the wall

The tap body, breech, mixer, or the joint where the shower arm connects. Water escapes into the wall cavity and shows up as a stain on the other side of the wall or on a ceiling below. Nothing you can see in the shower itself will look wrong.

At the waste

A perished seal at the waste flange, or a puddle flange that's separated from the membrane. Water tracks under the tiles and out through the floor.

Through the surface

Cracked or missing grout, perished silicone at the hob and wall junctions, a cracked tile, or a shower screen seal that's given up. Water gets past the tile face and into the screed.

Under the tiles

The waterproofing membrane has failed, or was never installed to standard. Water passes straight through the tile bed into the substrate.

This distinction matters because a regrout will not fix a leaking tap body, and fresh silicone will not fix a failed membrane. Working out which of the four you've got is most of the job. We pressure test the supply, isolate the shower, check the waste and moisture-map the surrounding walls and floor before recommending any leaking shower repair.

Shower Replacement Melbourne: When Repairs Won't Cut It

Most leaking showers are repairable. A shower replacement makes more sense when:

  • The waterproofing has failed across the whole shower rather than in one spot
  • The base has cracked or dropped out of level
  • Tiles are drumming or lifting across a wide area, which points to a broken-down tile bed
  • The leak has run long enough to damage the substrate, the framing or the room below
  • The same repair has been done two or three times and it keeps coming back
  • The bathroom is due for renovation anyway, and a repair would be money spent twice

We'll tell you honestly which side of that line you're on. For a shower replacement in Melbourne we handle the plumbing and waterproofing and coordinate the tiling, and because O'Shea covers plumbing, electrical, roofing and building trades, a shower replacement doesn't turn into you chasing four separate contractors.

Leaking Showers Melbourne: Why Call a Licensed Plumber?

Search leaking showers Melbourne and most of what comes back is regrouting and tiling businesses. They do good work when the problem is the grout. The limitation is that they can't touch the pipework.

A licensed plumber approaches leaking shower repair from the pipework out. We can pressure test the supply to the shower, isolate the tap body, inspect the waste, and use moisture meters and thermal imaging to trace where water is travelling. If it turns out to be grout, that's a straightforward fix. If it turns out to be a failing mixer or a cracked pipe in the wall, you've just avoided paying for a regrout that was never going to work.

O'Shea has been repairing leaking showers across Melbourne since 1978. Our plumbers are licensed, our work carries a 10-year workmanship guarantee, and leak detection happens before you're asked to commit to a repair.

Is a Leaking Shower Covered by Insurance?

It depends on the cause, and the line insurers usually draw is between sudden damage and gradual deterioration.

Often covered: sudden damageA pipe that bursts behind the shower wall is generally treated as a sudden escape of water, and is often covered.
Commonly excluded: gradual deteriorationDamage that has built up over years from perished silicone, failed grout or a membrane that was never right is usually treated as wear, maintenance or a defect.

Two things help if you're likely to claim:

  • Get the leak found and documented. A plumber's report identifying the cause and the date carries more weight with an insurer than a description of the damage.
  • Don't sit on it. Most policies expect you to act once you're aware of a problem, and a long gap between noticing and acting can affect what gets paid.

Policies differ, so check your PDS or ask your insurer rather than assuming either way. If you need a written report on the cause for a claim, a landlord or a body corporate, we can provide one as part of your bathroom shower repair. Melbourne homeowners often need one for a strata claim.

Leaking Shower FAQ's

Common signs of a leaking shower include water stains, peeling paint, mould growth, and damp smells. If you notice any of these, it’s best to get a professional inspection.

Yes! Water seeping into walls and floors can weaken structures, cause mould, and lead to costly repairs if left untreated. Addressing leaks early can prevent serious damage.

Our expert plumbers will assess your situation and advise you on the best course of action—whether a repair is feasible, or a replacement is the most effective solution.

The time required depends on the severity of the issue. Minor repairs can be completed within a few hours, while more complex issues may take a day or two.

Costs vary depending on the problem. We provide upfront, transparent pricing after assessing your shower, ensuring no surprises.

Often, yes – if the leak is in the surface. Resealing and regrouting needs no tile removal and holds up well on a surface leak. But if the waterproofing membrane underneath has failed, no surface treatment will fix it. Any business promising a permanent fix with no tiles removed, before anyone has diagnosed the leak, is over-promising. We establish which situation you’re in first.

It depends where the leak is, which is why diagnosis comes first. Grout, silicone and cracked tiles are tiling work. A leaking tap body, mixer, shower arm, waste or pipe in the wall is plumbing work and needs a licensed plumber. A failed membrane needs both. Starting with a licensed plumber means the pipework gets ruled in or out before you spend money on the surface.

A reseal and regrout on an otherwise sound shower should give you years, and epoxy grout systems typically carry a manufacturer’s warranty of around 10 years. A plumbing repair is permanent for the component replaced. A repair that fails within a year or two usually means the original diagnosis was wrong – a surface fix applied to what was really a membrane or plumbing problem.

Stop using the shower and get it looked at the same day if you can. Water reaching a ceiling below has been travelling through the floor structure for a while, and continued use adds to the damage. If it’s a supply leak, turn the water off at the shower isolation valves. Photograph the ceiling before anyone starts work, in case you need it for insurance or a body corporate.
