Quality criteria
What makes a good
Coolbinia bathroom renovation.
The unglamorous things that separate a bathroom renovation that lasts twenty years from one that leaks at year five. None of these show in finished photos. All of them matter.
Waterproofing
AS 3740 — not optional.
Wet area waterproofing must be certified to Australian Standard AS 3740. Inadequate waterproofing is the single most common cause of bathroom failure. We file the certificate at handover.
Falls & drainage
Floors that actually drain.
Floor falls to waste outlets must be set before tiling, not chased with grout afterwards. Hobless showers need millimetre-precision falls. We screed before we tile.
Ventilation
BCA-sized extraction.
Exhaust fans sized per Building Code of Australia ventilation requirements, not the cheapest fan in the catalogue. Mould and condensation are ventilation problems before they are cleaning problems.
Glazing
Toughened to AS 1288.
Shower screens, panels and frameless installations must be toughened glass certified to AS 1288. Cheap glazing is a safety failure waiting to happen, and it shows up immediately in the finish.
Fixtures
WaterMark certified.
Every plumbed fixture must carry WaterMark certification. It is a regulatory requirement, not a preference. We don’t install grey-market fixtures regardless of price-point pressure.
Substrate
Wet-area sheeting.
Walls and floors in the wet zone use rated sheeting and substrate, not standard plasterboard. The substrate is what tile sits on for the next twenty years.
