Bathrooms built during Erina's development era are now 40–50 years old. The original waterproofing membranes, drainage, and supply lines are past their service life. Renovation isn't just about aesthetics — it's about preventing water damage.
Soft or springy flooring, damp walls in adjacent rooms, or mould appearing persistently at tile joints. Failed waterproofing membranes in older Erina bathrooms are a significant hidden problem that gets worse over time.
Original shower and bath wastes in 1970s–80s bathrooms often have inadequate fall or collapsed traps. A renovation is the opportunity to install compliant drainage to current Australian Standards.
If your Erina home has original galvanised water supply lines running to the bathroom, a renovation is the ideal time to repipe them in copper or PEX — improving water pressure, eliminating rust, and preventing future burst pipe issues.
An updated bathroom is one of the highest-return renovations for Erina properties. With a strong owner-occupier base and proximity to Erina Fair (where bathroom fixtures are readily available), the cost-to-value ratio is excellent.
