A leaking shower rarely announces itself. It seeps quietly through failed grout, perished silicone or a hidden pipe, and the first you know of it is a stain on the ceiling below, swollen skirting, or mould creeping up the wall. Our licensed Sydney plumbers find the source of the leak and repair it properly, often without removing a single tile, with a $0 call-out fee and a fixed price before we start.
Shower leaking or water showing up where it should not be? Call 0461 330 531, and we will find it and fix it.

From pinpointing a hidden leak to resealing the shower, we cover the full job, and because we are licensed plumbers, we fix the plumbing causes that other shower repairers cannot.
We trace the source with leak detection equipment and, where needed, a flood test, so we fix the actual leak rather than guessing and tearing things up.
Cracked and failed grout was raked out and replaced, and the wet areas resealed to stop water from getting behind the tiles, usually with no tile removal.
Perished silicone stripped and replaced around the screen, corners and floor joints with quality mould-resistant sealant.
Leaking shower mixers, taps and wall connections repaired or replaced, the kind of in-wall leak only a licensed plumber should touch.
Cracked or poorly sealed shower wastes and floor drains are repaired or replaced, and the drain checked for blockages.
Corroded or burst pipes behind the shower wall located and repaired, with as little disruption to the tiling as possible.
The wider bathroom leak was sorted, including the damage showing up on the ceiling of the room below, traced back to its source and fixed.
A leaking shower is one of the most common and most costly plumbing problems in a Sydney home, because the damage builds up out of sight before anyone notices. R&G Plumbing, Gas & Drainage is a Gordon-based local team with close to two decades of experience tracing and repairing shower and bathroom leaks across Sydney. We work out whether the water is escaping through the waterproofing, the grout and silicone, or the plumbing behind the wall, then fix the actual cause rather than papering over the symptom.
Many shower leaks come down to a plumbing fault we repair every day, a worn shower mixer or tap, a leaking shower waste tied into the floor drain, or a pipe leaking behind the wall. Where the tiles, grout or silicone have failed, we reseal and regrout to stop the water, usually without ripping the shower out. Call 0461 330 531 to book a leak inspection.
No guesswork and no surprise bills. Here is exactly what happens from your first call.
Tell us what you are seeing, send a photo if it helps, and we will book a time that suits, with no call-out fee.
We inspect the shower and trace the source of the leak, using a flood test or leak detection where needed.
You get a clear, fixed price before we start, with nothing added on afterwards.
We repair the cause, reseal and regrout as needed, then test that the leak is gone and leave the bathroom clean.
Shower leaks are sneaky. The water often shows up in a different room from where it started, so these are the clues worth acting on early.
The longer a shower leaks, the further the water travels into framing, plaster and the room below, and the bigger the repair becomes. Catching it early usually keeps it to a simple reseal.
A leaking shower is either a waterproofing problem or a plumbing problem, and sometimes both. Here is what is usually behind it.
The hidden membrane under the tiles is what really keeps water in the shower. Once it cracks or breaks down with age, water passes straight through the tiles and into the structure.
Grout is porous and moves over time. Once it cracks, crumbles or falls out, water gets behind the tiles, the single most common cause of a slow shower leak.
The silicone around the screen, corners and floor joints perishes and lifts after a few years, opening a direct path for water to escape the shower.
A cracked or drummy tile lets water through to the bed beneath, and a tile that has lost its bond often indicates that the waterproofing beneath it has already failed.
A worn shower mixer, tap or wall connection can leak inside the wall cavity, where you never see the drip, only the damp patch it leaves behind.
A poorly sealed or cracked shower waste lets water escape under the floor every time you shower, often mistaken for a tiling fault.
Hot or cold water pipes feeding the shower can corrode or fail inside the wall, leaking continuously whether or not the shower is running.
We find the real source before we touch anything, so you get the right repair the first time.
we inspect the shower, check the grout, silicone, tiles, mixer, waste and pipework, and run a flood test or leak detection where the source is not obvious.
leaking mixers, taps, wastes and in-wall pipes repaired or replaced, the parts of the job that need a licensed plumber.
failed grout replaced, wet areas resealed and silicone renewed to stop water getting behind the tiles, usually with no tile removal.
we re-test the shower, including a flood test where appropriate, to confirm the leak is gone before we leave.
if the waterproofing has failed beyond a reseal, we explain the options honestly so you can decide with the full picture.
The good news for most Sydney homeowners is that a leaking shower rarely means ripping out the bathroom and starting again. In the majority of cases, the leak is stopped by raking out and replacing failed grout, resealing the wet areas and renewing the silicone, all without removing the tiles.
That makes the repair faster, cleaner and far cheaper than a full re-tile, and you are usually back to using the shower within a day or two. Where we find the plumbing is at fault, a leaking mixer, waste or pipe, we repair that directly. Only where the waterproofing membrane has genuinely failed beyond a surface reseal will a bigger fix be needed, and if that is the case, we will tell you straight, explain the options, and never push an expensive job you do not need.

Here is how R&G compares when you want a leaking shower found and fixed properly.
| R&G Plumbing | Other Plumbers | |
|---|---|---|
| Call-Out Fee | $0 call-out fee on every job | Hidden or added call-out charges |
| Diagnosis | Leak detection and flood testing to find the real source | Guesswork, or only resealing the surface |
| Scope | Licensed for the plumbing causes too: mixers, wastes, pipes | Sealing only, plumbing leaks left unfixed |
| Disruption | Most leaks fixed with no tile removal | Quick to recommend a full re-tile |
| Pricing | Clear, fixed quote before work starts | Vague estimates and surprises |
| Guarantee | Workmanship backed by a guarantee | Little or no cover on the work |










It depends on the cause. A regrout and reseal is a modest job; repairing a leaking mixer or an in-wall pipe is different again. Because there is no call-out fee and we quote a fixed price before starting, you always know the cost before any work happens, with nothing added on afterwards.
In most cases, yes. The majority of shower leaks are stopped by replacing failed grout, resealing the wet areas and renewing the silicone, all without removing tiles. It is faster, cleaner and far cheaper than a full re-tile. Only where the waterproofing membrane has failed beyond a reseal is a bigger job needed, and we will tell you straight if that is the case.
We inspect the grout, silicone, tiles, mixer, waste, and pipework, and where the source is not obvious, we run a flood test or use leak-detection equipment to pinpoint it. Finding the real source first is what stops the leak from coming straight back.
Very often, yes. A shower leaking through failed grout, silicone or waterproofing, or a leaking waste or pipe, will travel down and show up as a stain or mould on the ceiling below. We trace it back to the source in the bathroom and fix the cause, not just the stain.
A proper regrout and reseal, done over sound waterproofing, lasts for years. Where we have repaired a plumbing leak, the fix is permanent. If the underlying membrane is failing, a surface repair buys time, but we will be upfront that a longer-term fix may be needed.
Sudden water damage is sometimes covered, while slow, long-term leaks often are not, so it comes down to your policy. We can provide a report and photos of the cause and the repair to support a claim.
Yes, and that is the difference. As licensed plumbers, we repair the shower mixer, taps, waste, and any in-wall pipe leak, which causes a sealing-only repairer cannot touch, as well as regrouting and resealing the shower.
No. There is no charge for us to come out and assess the leak anywhere we service in Sydney. You only pay once you have approved a clear, fixed quote, and seniors and pensioners save 10% on every job.
