Quality criteria

What makes a good
Perth 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.

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’re 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 in a Perth bathroom must carry the WaterMark certification. 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.

Common questions

Bathroom renovations Perth
the questions we
get.

The questions Perth homeowners ask before a bathroom renovation brief. Plain answers, plain English.

Two weeks for a cosmetic refresh. Three to four weeks for a full strip-and-rebuild keeping the existing footprint. Four to six weeks for a high-end custom build with structural changes. Programme is committed to in calendar weeks at quote — not “rough estimates” — and reported against weekly.

If your home has a second bathroom or ensuite, you can stay during the renovation. If it’s your only bathroom, most clients arrange to be away for the wet-tile-and-grout phase (typically 4–7 days mid-programme). We’ll flag the exact dates well in advance.

Most internal bathroom renovations don’t require council approval — the work happens within the existing footprint. Approval is required if you’re moving a bathroom to a new room, adding a bathroom (extension), or making structural changes. We assess what’s needed at the brief stage.

Yes — we’ll specify the allowance for each line and you can supply your own up to or beyond that allowance. Plumbed fixtures must carry WaterMark certification (a regulatory requirement, not a preference). Bring tile selections to the quote stage so they can be priced and ordered against the programme.

Twelve months of direct aftercare from handover — defects logged on the direct line are responded to within five business days. Statutory warranty under the WA Home Building Act applies on top of that. Waterproofing is certified separately and that certificate runs for the life of the membrane.

Most bathroom renovation companies Perth-wide work as design-and-quote brokers — they take the brief, then sub the build to whoever’s available. GPD is different: a single WA-licensed builder runs every job. As a bathroom renovation company Perth homeowners brief directly, the person who quotes the work owns the outcome.
