Bathroom Renovations in Preston
Preston sits at the point where the inner-north's Californian bungalows and Edwardians give way to Reservoir's post-war stock. Most Preston bathroom renovations we quote are in homes that have already been extended or partially renovated — the kitchen is done, the living areas have been opened up, and the bathroom is now the last dated room. Layouts are usually tight and constrained by an external plumbing wall, which means a good renovation depends on a designer who can actually stretch every millimetre.

Why homeowners in Preston choose Vision Line
Preston clients tend to be design-literate — they have researched tapware brands, know the difference between honed and polished travertine, and want a builder who will not talk down to them. We treat every Preston quote as a design conversation first and a build quote second. Everything ends up in one fixed-price contract with materials specified line by line.
- Fixed-price contracts, no surprise variations
- Licensed plumber + electrician on every job
- AS3740-compliant waterproofing certificate
- Six-year workmanship warranty
- $20M public liability insurance
- Photographic waterproofing sign-off
Built for Preston homes.
Older Preston homes commonly have galvanised or lead-lined supply plumbing that must be replaced in copper or PEX-B during rough-in — we quote this in advance rather than as a variation. Heritage overlays apply on some Preston streets; we check Darebin's HO maps before any external work.

Twelve stages. Same order, every job.
Every Preston bathroom runs the same twelve-stage build: site protection, demolition, plumbing and electrical rough-in, wall and floor preparation, screeding, waterproofing, tiling, vanity and cabinet fit-off, shower screen, detailed clean and final handover.
Everything under one contract
Built for how Preston homes actually live.
Every material we specify for a Preston bathroom has to earn its place three ways: it has to look right in the home, it has to hold up under Melbourne water conditions, and it has to be maintainable ten years from now — not just at handover.
- Tiles
P3/P4-rated porcelain on floors and shower zones (slip-safe when wet). Natural stone reserved for feature walls to avoid ongoing sealing.
- Grout
Waterproof epoxy grout in wet zones — no cracking, no mould regrowth, no re-grouting inside the warranty period.
- Tapware
WELS-rated tapware with 15-year manufacturer warranty. Brushed brass and gunmetal finishes are PVD-coated (not electroplated) to survive Melbourne water hardness.
- Joinery
Moisture-resistant board substrate on every vanity carcass — not standard MDF, which swells in a wet-area cabinet within four years.
Frequently asked in Preston.
Can you add an ensuite to our Preston Californian bungalow?
Yes. In bungalows the easiest ensuite is usually carved from a rear bedroom or laundry, drawing plumbing off the existing main-bathroom wall to minimise slab or floor cuts. Typical build is four weeks including cabinetry.
How do you handle the narrow bathrooms typical in Preston?
We use continuous floor drainage (linear grates), frameless shower screens, and floating vanities to keep sight-lines open. Removing the bath in favour of an oversized walk-in shower is by far our most-requested change in Preston.
Do you replace old galvanised pipes as part of the reno?
Where they are exposed by demolition, yes — replaced in copper or PEX-B and quoted upfront. Anything found beyond the bathroom is quoted as a documented variation before we touch it.
Do you provide fixed pricing?
Yes. Every quote we issue is fixed in writing before demolition begins, including tiles, tapware, waterproofing, plumbing, electrical and rubbish removal. There are no hourly surprises.
Are your trades licensed and insured?
All plumbing is completed by a licensed Victorian plumber who issues a Certificate of Compliance. All electrical work is completed by an A-Grade electrician who issues an Electrical Safety Certificate. We carry $20M public liability insurance.
How long does a bathroom renovation take?
A standard main bathroom takes three to four weeks on site once demolition starts. Ensuites usually run two and a half to three weeks. Timelines are written into the contract with a start and finish date.
Reading that pays for itself.
