Frequently Asked Questions about Shower Plumbing

There are several reasons your shower might be leaking, and addressing the issue quickly is essential to avoid more extensive damage. Common causes of shower leaks include:

  • Building movement: Over time, buildings naturally shift and settle. Rigid materials like tiles and cement can’t adapt to these movements, leading to gaps between walls and floors that allow water to escape.
  • Waterproof membrane failure: A waterproof membrane is vital to keeping your bathroom leak-free. Poor installation or low-quality materials can cause the membrane to deteriorate, resulting in leaks.
  • Damaged silicone seals: The silicone seals in your shower corners and edges are designed to keep water contained. If these seals are cracked, worn, or missing, water can seep out, causing damage.
  • Cracked or missing grout: Shower grout, especially when cement-based, can deteriorate over time. This creates pathways for water to escape and fosters mould growth in damp areas.

Addressing these problems early can save you from costly repairs and protect your bathroom from long-term water damage.

Watch out for these signs that your shower may be leaking:

  • Loose or cracked tiles: Shifting or broken tiles often signal water damage beneath the surface.
  • Damp or stained walls: Warping, discolouration, or damp spots on walls near the shower indicate hidden water damage.
  • Musty odours: Persistent unpleasant smells may point to mould or water accumulation due to a leak.
  • Peeling or bubbling paint: Paint issues around your shower are a common sign of excess moisture from leaks or poor ventilation.
  • Darkened or missing grout: Discolouration or gaps in grout allow water to seep under tiles, which can quickly escalate into a bigger problem.
  • Warped shower doors: If your shower door becomes difficult to close, it could be due to structural warping caused by hidden water damage.

Identifying these warning signs early can prevent further water damage and expensive repairs, keeping your bathroom in top condition.
