Leaking Shower Repairs Across Wollongong & Illawarra

A leaking shower might look minor, until it isn’t. Left unfixed, a shower leak can rot your subfloor, breed serious mould, and push your water bill up by hundreds of dollars a year. Curran Plumbers diagnose and fix leaking showers fast, across Wollongong, the Illawarra, Shoalhaven, and surrounding NSW areas.

Whether your shower leaks from the base, seeps through the ceiling below, or drains too slowly, our team has seen it all and fixed it all. Most jobs are resolved in a single visit.

Signs You Have a Blocked Drain

Not every wet floor means a leak, but these are strong signs you need a plumber:

  • Water pooling outside the shower recess on the bathroom floor
  • Wet or stained ceilings in the room below your bathroom
  • Mould or mildew growing on grout or silicone that keeps coming back
  • Peeling paint or bubbling plaster near the shower walls
  • Musty smell in the bathroom that doesn’t clear with ventilation
  • Unexplained jump in your water bill
  • Cracked, crumbling, or loose tiles inside the shower

Common Causes of Leaking Showers

Failed Waterproofing Membrane

Water bypasses the tiles entirely and soaks into the structure below, often undetected for months.

Cracked or Missing Grout

Gaps between tiles let water seep behind the wall, slowly saturating the substrate.

Deteriorated Silicone Seals

Silicone at corners and edges breaks down over time, opening gaps where the shower meets floors and walls.

Leaking Shower Drain

A poorly sealed or cracked drain lets water escape under the base with every use.

Leaking Shower Head or Mixer

Faulty tapware wastes water and may be pushing moisture into the wall cavity behind the tiles.

Cracked Shower Base or Tray

Hairline fractures in the shower pan allow water to leak through every time someone showers.

Frequently Asked Questions

Cost varies depending on the cause and scope of the repair. Minor resealing is straightforward; a failed waterproofing membrane may require more work. We always provide a clear upfront quote before starting. Call us for a free assessment.

If the leak is minor with no visible structural damage, short-term use may be okay. However, every shower worsens the underlying damage. The sooner you book, the cheaper the fix.

Yes, and it needs urgent attention. Ceiling penetration means water has already saturated the subfloor or structural timbers, which leads to mould, rot, and serious damage if left. Call Curran today.

Not always. Many leaks are resolved by regrouting, resealing, or waterproofing without removing all tiles. Our plumbers will give you an honest assessment; we won’t oversell the job.

Some policies cover sudden and accidental water damage. Gradual leaks are often excluded. Check your policy and contact your provider directly — we can provide a detailed repair report if needed.
