Australian Waterproofing Standards for Leaking Shower Repairs

Andrewlope24 Apr, 2026Business

Bathroom construction in Australia must comply with strict guidelines. Poor waterproofing has always been a major reason behind leaking showers, particularly in renovated properties and those constructed before the Australian standards came into effect. The key standard is AS 3740 – WATERPROOFING OF DOMESTIC WET AREAS. Experts in leaking shower services should not cut corners at all, because the result will be easy to predict: leaking showers or a failed process within just a couple of years.
