Bathroom renovation
in Fremantle that won't leak on the neighbours

Bathroom renovation in Fremantle done to the letter: strip to slab, AS 3740 waterproofing with flood test, large-format tiling, brassware and fit-off. From $24,000, four to seven weeks, waterproofing certificate in the handover pack.

01 // The short version

The smallest room, the highest stakes

A bathroom is 4 square metres of concentrated liability. Get the waterproofing wrong and you're paying for two apartments' repairs — yours and the one below. It's the room where we see the most corner-cutting from cheap quotes, and the room where ours is most boringly thorough.

Every wet area gets stripped to slab, re-screeded to falls, membraned twice, flood-tested for 48 hours and photographed at every stage before tiling. That process is why our bathrooms pass strata inspection first go — the strata article explains what committees look for.

02 // Scope

What's actually included

The same list goes into your contract, line for line. If it's not here, it gets quoted separately — not invoiced quietly later.

I.01Strip to slab

Everything out — tiles, fixtures, old membrane. Slab checked for damage and repaired before anything new goes down.

Included
I.02Plumbing rough-in

New in-wall rough-ins, mixer bodies, waste positions set for the new layout. Licensed plumber, pressure-tested.

Included
I.03Screed & falls

Fresh screed graded to the waste — water goes to the drain, not under the door. Falls verified before membrane.

Included
I.04Waterproofing

Two coats to AS 3740 with bandage at every junction, then a 48-hour flood test. Photos and certificate in your pack.

Included
I.05Tiling

Large-format porcelain standard, epoxy grout in the shower zone, mitred or trimmed edges to your spec. See the tiling scope.

Included
I.06Fit-off

Vanity, WC, brassware, screen, mirror, accessories — siliconed, sealed and tested. Extraction fan ducted properly.

Included

04 // Process

How the job runs

Same playbook as every Apex job — measured, scheduled, reported every Friday. The about page covers the company side.

WEEKLY REPORTS

Photos of every stage land on your phone each Friday, including the hidden work before walls close.

Friday photo report from an Apex renovation — hidden services photographed before walls close
Actual Friday report frame
  • Measure & layoutWe check falls, riser locations, vent paths and what your strata requires. Some Fremantle buildings specify membrane brands — we know which.
  • Strip & rough-inThree to four days of noise. New in-wall plumbing goes in, pressure-tested and photographed before closing.
  • Screed, membrane, flood testThe unglamorous week that decides whether this bathroom exists in ten years. Photos at every step go in your report.
  • Tiling & fit-offPete's crew lays the tile, fits the brassware and screens, then silicones everything. Mitred edges where you want them.
  • Test & handoverEvery fixture run, falls re-verified, certificate issued. You shower in it before we call it done.
05 // Materials & spec

What we put in, and why

Membrane systems we trust

Ardex and Gripset systems, applied to manufacturer spec with bandage at every junction and upturn. The brand matters less than the application — we do both properly.

Tiles & grout

600×600 or 1200×600 porcelain is the sweet spot for small bathrooms — fewer grout lines, bigger feel. Epoxy grout in showers costs more and means you never re-grout. Ever.

Brassware honesty

Brushed brass looks great and shows water spots. Matte black shows soap. Chrome is boring and bulletproof. Pick with your eyes open — we'll lay out real samples at selections.

06 // Questions

Asked before this job starts

Different scope, different worries — these are the ones clients put to us first.

Four to seven weeks end to end, with the toilet unusable for about two of them mid-job. In a one-bathroom flat, clients usually shower at a gym or stay elsewhere for that stretch — we map the dates before you commit.

Two coats with cure time between them, then 48 hours of flood test watching for level drop. It's a week where the room looks like nothing's happening — it's actually the week that stops a $40k neighbour claim in five years.

Toilets are the hard one — the waste is usually a shared stack, so moves are short and strata-dependent. Showers and vanities relocate more easily. We'll tell you at the measure what's movable in your building specifically.

Our 5-year workmanship warranty covers the install — waterproofing, tiling, plumbing fit-off — plus manufacturer warranties on fixtures (10+ years on quality brassware). The certificate pack lists every one.

Showers shouldn't be gambles.

Book the measure — we'll check your falls, your riser and your strata rules before quoting a cent.
