Signs Your Lake Haven Bathroom Needs Renovation Plumbing

Failed shower waterproofing

Cracked or lifting tiles, damp wall cavities, or mould behind the shower wall are signs the original waterproofing membrane has failed. In Lake Haven's 1970s–80s homes, many showers were waterproofed with materials that are now 40+ years old and well past their service life.

Leaking shower causing subfloor damage

A shower that's been leaking for years will eventually rot the timber subfloor and framing. If your bathroom floor feels soft or bouncy, or you can see water staining on the ceiling below, the structural damage needs addressing now before the renovation cost grows further.

Corroded pipes behind the walls

A bathroom renovation is the best opportunity to replace galvanised iron supply lines behind walls with copper or PEX — the wall is already open. If you're renovating a pre-1980 Lake Haven home, factor in pipe replacement to avoid opening walls again in five years.

Relocating fixtures or changing the layout

Moving a toilet, shower, or bath to a new position requires new drainage runs to the existing sewer stack. This is licensed plumbing work under the NSW plumbing code and requires inspection. Get it right the first time.

Bathroom hasn't been renovated since the 1980s

Most Lake Haven homes haven't had their original bathroom touched. At 40–50 years old, every plumbing component in the room is at or past its expected lifespan. A full renovation now is far more economical than repeated reactive repairs over the next decade.
