You spotted the stain on the ceiling below the bathroom, or the grout that’s gone black no matter how hard you scrub — and now you’re bracing for the worst: a quote that balloons into a $25,000 bathroom rebuild. Take a breath. For the large majority of leaking showers in Brisbane, that’s not what happens. On average, a leaking shower repair in Brisbane costs between $800 and $2,500 in 2026 when the fix is a professional regrout and reseal with no tiles removed. Minor silicone-only resealing can be a few hundred dollars; a full strip-out and re-waterproof (only needed when the membrane behind the tiles has actually failed) is where prices climb into the thousands. A complete bathroom renovation — the option people fear — sits at a completely different level, around $20,000 to $40,000. This guide breaks down the real numbers, the six things that move the price up or down, when a cheap reseal is genuinely enough, and how to make sure you don’t overpay (or underpay for a job that fails in 18 months). What Does a Leaking Shower Repair Actually Cost in Brisbane? Here’s the honest range for 2026. Every shower is different, so these are guides — the only accurate number comes from an on-site look — but they’ll tell you which ballpark you’re in. Type of repair What it covers Typical 2026 Brisbane price Shower screen reseal (silicone only) Re-siliconing screen edges, corners and the floor-to-wall junction where the old sealant has gone black or pulled away $300 – $600 Standard regrout + reseal (no tiles removed) Removing failed grout to depth, cleaning and prepping, epoxy regrout, resealing all joints — the most common leaking-shower fix $800 – $2,500 Large / double shower or stubborn grout Same job, but bigger area, mosaic tiles, or hard old grout that needs mechanical grinding $2,000 – $3,000+ Full strip-out & re-waterproof + re-tile Tiles removed, new waterproofing membrane, re-tiling — needed only when the membrane has failed or tiles are cracked/drummy $3,000 – $15,000 Complete bathroom renovation Whole-room rebuild: new fixtures, layout, full waterproofing, all trades $20,000 – $40,000+ The takeaway most Brisbane homeowners are relieved to hear: if your tiles are sound and the leak is coming through failed grout or silicone, you’re almost certainly in the $800–$2,500 band, not the renovation band. The expensive jobs are the exception, not the rule. If you want to understand exactly what’s going wrong before you call anyone, our guide to leak detection and leaking shower repairs walks through how we find the source. 6 Things That Change The Price Two showers that look identical can quote differently. Here’s what actually drives the number on your quote. 1. How bad the leak is A bit of failed grout or perished silicone is a quick, low-cost fix. Water that’s already tracked into the wall, rotted timber framing, or soaked the floor below is a bigger job — and the longer it’s left, the more it costs. Catching a leak early is the single biggest thing you can do to keep the bill down. 2. The size and layout of the shower A standard recess (roughly 1m × 1m — if you can stand in the middle and touch both walls with your arms out, that’s standard) is the baseline. Walk-in showers, double showers, and full floor-to-ceiling tiling have more grout lines and more area, so they take longer and cost more. 3. The condition of your tiles If tiles are intact, the repair stays simple and surface-level. If several are cracked, loose, or “drummy” (they sound hollow when tapped), that’s a sign water has already compromised what’s underneath — and a surface reseal won’t fix it. Tile repair or partial re-tiling adds to the scope. 4. Epoxy grout vs cement grout Cheap cement grout is porous and tends to fail again within a few years. Epoxy grout is waterproof, mould-resistant and lasts far longer — but it costs more and demands skilled application. Paying a little more for epoxy is almost always cheaper over the life of the shower because you’re not back here in three years. We cover the trade-offs in detail in our regrouting and tile repairs service. 5. Whether the screen or plumbing is involved If the shower screen needs removing and refitting, or the leak turns out to be plumbing behind the wall rather than the surface, that changes the work. A proper inspection separates a surface (sealing) problem from a plumbing problem before any quote is locked in. 6. Access Second-storey showers, tight ensuites, awkward corners and limited access all add labour time. It’s not glamorous, but how easy the shower is to physically work in genuinely affects the price. Repair vs replace: when a reseal is enough — and when it isn’t This is the question that decides whether you spend hundreds or tens of thousands. A regrout and reseal is enough when: Your tiles are in good condition (not cracked, not drummy) The leak is coming through cracked grout, porous grout, or perished silicone at the joints There’s no soft, spongy feeling when you press on wall tiles There’s no major water damage already showing in the room below You need more than a surface repair when: Tiles are cracked, loose, or sound hollow when tapped The waterproofing membrane behind the tiles has failed Water has caused structural damage to framing or the subfloor A previous surface reseal was done and the leak came straight back The honest reality: a regrout can’t fix a failed membrane. If that’s what’s going on, resealing the surface just buys a few months before the leak returns. A reputable repairer will tell you that at the quote rather than taking your money for a fix that won’t hold. If you’re not sure which camp you’re in, our regrouting and tile repairs and bathroom and balcony retiling pages explain both paths.
