Signs of a Leaking Shower

A leaking shower can lead to serious water damage if left unnoticed. From minor cracks to hidden water seepage, even small issues can turn into expensive repairs if not addressed early. Knowing the warning signs of a leaking shower is essential for protecting your bathroom and avoiding structural damage to your home.

Common Warning Signs

1. Damp or Peeling Paint on Adjacent Walls

If the paint on the wall behind or next to your shower is peeling, bubbling, or discoloured, this could be a clear sign of moisture escaping from behind the tiles.

2. Musty Smell in the Bathroom

A persistent damp or mouldy smell is a strong indicator that moisture is building up in areas that aren’t properly ventilated—often due to a hidden leak.

3. Mould or Mildew Growth

Black spots of mould, especially on the ceiling or walls near the shower, often point to excess moisture leaking through cracks or tile joints.

4. Cracked or Missing Grout

Grout that’s cracked or falling away can allow water to seep through, especially in tiled showers. If water consistently escapes, it can damage the wall behind the tiles.

5. Loose or Drummy Tiles

Tiles that sound hollow or feel loose underfoot or on the walls might have water damage underneath, which often results from a leak.

6. Water Stains on Ceilings Below

For bathrooms on an upper level, yellow or brown water stains on the ceiling below the shower can signal an active leak through the floor or waterproofing membrane.

7. Swollen or Warped Skirting Boards or Floors

Timber skirting boards or flooring that have started to swell, warp, or stain near the shower indicate prolonged exposure to water—often from a slow leak.

8. Excessive Water Usage or High Water Bills
A leak that continues while the shower is off can lead to unusually high water bills. This is less common, but still worth investigating if other signs are present.

Don’t Ignore the Signs

Even if the signs seem minor, a leaking shower can cause serious structural damage over time. If you’ve noticed any of the above symptoms, it’s a good idea to book a professional inspection. Prompt repairs—such as regrouting, resealing, or fixing damaged tiles—can save you thousands in long-term water damage repairs.
