Why waterproofing is never the place to save
A failed membrane behind your tiles leaks into walls, floors and framing, and you often do not notice until the damage is done. Fixing it means tearing out finished tiling, drying the structure and starting again, which costs many times the original waterproofing.
In South Australia, wet-area waterproofing must comply with Australian Standard AS 3740 and should be carried out by a licensed applicator. That compliance is exactly what protects you if anything ever goes wrong.
- Waterproofing must be done before tiling, to Australian Standards
- It should be carried out by a licensed applicator, not a handyman
- A compliant job comes with documentation you can rely on
- Cutting corners here is the single most expensive tiling mistake
What affects the cost
The wet area size drives most of the cost, but the type of area matters too. A full bathroom with walls waterproofed to height needs far more membrane than a shower recess alone.
Tight or upstairs access, multiple wet areas and extra detailing around drains, hobs and penetrations all add to the price. The estimate builds these in as a guide.
