Waterproof membrane failure is gradual and often invisible until damage has already spread into the surrounding structure. Catching it early keeps the repair scope and cost significantly smaller. Five signs your bathroom waterproofing needs attention:
A shower that is leaking into the wall or floor despite grout and silicone being intact
Damp patches on walls or ceilings adjacent to the bathroom that do not dry out
Tiles that have lifted or are hollow-sounding when tapped, indicating substrate damage beneath
Persistent mould growth in or around the shower that returns after cleaning
Soft or spongy flooring beside the shower indicating water penetration into the subfloor
A leaking shower where the visible grout and silicone look intact is a strong indicator that the waterproof membrane beneath has failed. In this case, regrouting alone will not stop the leak and bathroom waterproofing repair is required.
VIP Shower Repairs provides four core waterproofing services across Melbourne:
Shower waterproofing repair. Removal of failed membrane and affected tiles, new compliant membrane applied, retiled to match where possible.
Full bathroom waterproofing for renovations. Full waterproofing system applied to floor and walls before tiling on renovated or stripped-back bathrooms.
Wet area waterproofing for new installations. Membrane applied to bare substrate before tiling, meeting AS 3740 requirements.
Shower resealing. Silicone junctions resealed where the membrane is still intact. We assess first to confirm resealing is sufficient.
Over 20 years of experience in bathroom waterproofing and wet area rectification means we have assessed and repaired every waterproofing failure type common to Melbourne homes. We work exclusively on shower repairs and waterproofing, so every job receives the same level of focus regardless of scope.
All waterproofing is applied to AS 3740 compliance and backed by a written warranty. We use materials from National Tiles, Bella Vista, and Western Distributors, selected for long-term waterproofing performance in Melbourne's climate. We do not apply new membrane over failing substrate without preparing the surface correctly, because membrane applied to a compromised substrate fails prematurely regardless of the material quality.
Cost depends on the scope of the repair, the size of the shower or wet area, and whether tile removal and retiling are required. A shower resealing costs significantly less than a full membrane repair that involves tile removal. VIP Shower Repairs provides a free written quote after inspecting the bathroom, so the scope and cost are confirmed before work starts. Call 0404 607 006 to book.
In most cases of membrane failure, no. The waterproof membrane is applied beneath the tiles, so accessing and replacing it requires tile removal. Shower resealing, which repairs failed silicone junctions at the surface, can be done without removing tiles, but it only addresses surface seal failure rather than membrane failure. We confirm the correct scope after inspection.
Most waterproofing membranes used in shower repairs require a minimum of 24 to 48 hours curing time before tiling can begin, and the shower should not be used until the full installation including tiling and grouting is complete and cured. Curing times vary by product. We advise on the specific timeline at the quoting stage.
A correctly applied waterproof membrane in a bathroom typically lasts 10 to 15 years or more, depending on the membrane type, the quality of installation, and the conditions in the bathroom. Waterproofing that was applied below the minimum standard at original installation, or that has been compromised by movement or damage, may fail earlier. Regular inspection of grout and silicone condition is the practical way to catch early signs of waterproofing failure.
Yes. Australian Standard AS 3740 governs bathroom waterproofing in domestic wet areas and specifies minimum requirements for how membranes must be applied. Non-compliant waterproofing can cause issues with insurance claims and property sales. All waterproofing completed by VIP Shower Repairs meets current AS 3740 requirements.
