If you have noticed damp walls, mould, loose tiles or a musty smell around your bathroom, you might be dealing with a leaking shower. It is one of the most common issues in homes across Brisbane, the Gold Coast and the Sunshine Coast. When it is ignored, it can lead to serious structural damage that costs thousands to repair.
This guide explains why showers leak, how to spot the signs early, and what your repair options are. Whether you are a homeowner or a property manager, these steps will help you protect your property and avoid preventable damage.
A leaking shower is not always caused by faulty grout. There are usually deeper issues at play.
Waterproofing is the barrier beneath the tiles that keeps water out of the walls and floors. If this membrane breaks down, separates, or is not installed correctly, water travels into the structure.
Standard cement grout absorbs moisture over time. As it deteriorates, tiny pathways open up and allow water to escape.
Silicone creates a flexible seal at the corners and edges of a shower. When it cracks or splits, water easily runs behind the tiles.
If the floor does not slope correctly toward the drain, water pools instead of moving away. Over time, this pooling leads to leaks.
Tap fittings, old screens and poor sealing can also push water into areas that should stay dry.
