Hills District
Bathroom Renovations Castle Hill
Most Castle Hill bathrooms we're called into are the original 1990s fit-out: cream tiles to waist height, a framed shower screen with a rusted track, and a vanity that's swollen at the base. The room isn't broken, it's just done.
Castle Hill houses are generally generous — double-storey brick on 600–800sqm blocks, main bathroom plus ensuite upstairs, powder room down. That means two wet areas sitting over a timber floor, so substrate and waterproofing detail matter far more than the tile you pick. We price the main and the ensuite as separate line items so you can stage them or do both while the trades are already on site.

Castle Hill homes, and what that means for your bathroom
Most of our work sits in the Hills, so a Castle Hill job isn't a detour for us. Hills homes tend to be double-storey brick with a main bathroom and an ensuite upstairs over timber floors, which changes how we sheet, fall and waterproof the room. We also know how the estate streets and school-run traffic behave, so deliveries and skips are staged rather than dumped on day one.
Housing around Castle Hill
Established brick-and-tile family homes from the 80s and 90s, alongside newer dual-occupancy and townhouse developments.

We measure your Castle Hill bathroom, work through the layout with you, then put every item in writing — tiles, tapware, waterproofing, rubbish removal. No costs hidden behind a line called "allowances".
Renovating in Castle Hill
What we usually find in Castle Hill bathrooms
The age and build of the house sets the scope long before the tiles do. Here's what we plan for around Castle Hill.
01
Late-80s Castle Hill bathrooms typically have sand-and-cement beds over slab — full removal is the only honest starting point.
02
Dual-occ builds share walls and services; we isolate wet-area plumbing so the neighbouring dwelling keeps running.
03
Families here almost always want a bath kept in the main and a walk-in shower in the ensuite.
Castle Hill specifics
How a Castle Hill bathroom renovation runs
The parts of the job that are specific to this area, worked out at the measure rather than mid-demolition.
Two wet areas, one trade run
Doing the main and the ensuite together in the same three to four weeks saves a second mobilisation of waterproofer, tiler and plumber — usually the single biggest saving available on a Castle Hill job.
Upstairs timber floors
We check joist spacing and stiffen the substrate before sheeting, then step the shower floor properly instead of relying on a hob and hope.
Resale-aware finishes
Castle Hill buyers notice bathrooms. We steer toward large-format tiles, wall-hung vanities and semi-frameless glass that read current for a decade rather than a season.

Questions
Common questions from Castle Hill homeowners
Short answers to what people ask before booking a measure.
Yes, and it's usually the smart move. Both rooms in one run is around three to four and a half weeks and cuts the duplicated trade call-outs. We quote them as separate lines so you can still choose to do one now and one later.
It's the risk we plan for first. Upstairs bathrooms get a licensed waterproofer, AS 3740 detailing at every junction, photos at each coat and a compliance certificate at handover.
We schedule deliveries outside peak and stage materials rather than dropping everything on day one, so your driveway isn't a storage yard for a month.
Most full main bathrooms here land between $24,000 and $38,000. Ensuites are usually $18,000 to $26,000. Layout changes and stone selections shift it more than anything else.
Yes — Castle Hill is part of our regular run, so our trades and suppliers are already local. No travel surcharge.
Usually within a week. The site measure takes about an hour and you get the quote a few days later.
Three to four weeks. If it's your only bathroom we'll stage the work or sort a temporary option so the household keeps running.
Every job. Done to AS 3740 by a licensed waterproofer, with photos and a compliance certificate handed to you.
Most full renovations land between $22,000 and $38,000. Layout changes and tile choice move the number more than anything else.

How it works
What happens once you say yes?
Three stages and three to four weeks on site. You'll know the price before we start, how long the bathroom is out of use, and who is turning up each morning.
Measure, design and written quote
We measure the room, check the drainage and what's behind the walls, then give you a scaled layout with every fixture listed and a written price that holds once it's signed.
Strip-out, rough-in and waterproofing
Back to frame, licensed plumbing and electrical rough-in, then waterproofing to AS 3740 photographed at every coat. Same crew, same start time, swept down before we leave each day.
Tiling, fit-off and handover
Tiling, glass measured off the finished walls, tapware and joinery installed. Then we walk the room with you, fix anything you pick up, and hand over the certificates and a workmanship warranty.

Answers
More questions from Castle Hill homeowners
We hold a NSW Builder Licence (#393475C) and every trade is licensed and insured. You meet the person running your build at the site measure, not after demolition starts. We also provide a detailed written contract with every item listed before work begins, and a workmanship warranty at handover.
Not if we've measured the site properly. Our quote is a detailed written contract that lists every fixture, tile and fitting by supplier code. If there is a risk we can't see — like asbestos or hidden water damage — we itemise a provisional sum upfront so you know the ceiling before you sign, not after the wall is open.
Most full bathroom renovations in Sydney land between $22,000 and $38,000 for a standard 6–8m² room, with premium and larger builds running $40,000 to $70,000+. The variables that move the number most are whether fixtures stay in place, the tile size and format, whether the room contains asbestos, and the standard of tapware and joinery. We give you a detailed written contract after the site measure so the scope and price are clear before you sign.
A standard full renovation takes three to four weeks on site: demolition and rough-in week one, waterproofing and screed week two, tiling week three, fit-off and finishing week four. We keep the rest of your home live wherever possible, and waterproofing membranes need proper cure time — we don't compress that, because it's the single most common cause of failures we're called in to repair.
Usually no. A like-for-like internal bathroom renovation in NSW is generally exempt development. You will need approval if you are altering the external envelope, changing the building's structure, or the property is heritage listed or in a conservation area. Strata apartments need owners corporation approval regardless. We tell you which category you're in at quote stage.
Waterproofing is carried out by a licensed waterproofer to AS 3740 and you receive a certificate of compliance plus photographic evidence of the membrane before tiling. It's covered by our workmanship warranty. We never allow a tiler to 'roll a bit of membrane on' as part of the tiling day.
No — the room is stripped to the frame. If your home has a second bathroom or powder room we keep it live throughout. Where the renovated room is the only bathroom, we can stage the works or arrange a temporary toilet so the household isn't displaced.
We test suspect materials before demolition rather than discovering them mid-job. If asbestos is present, a licensed removalist handles it and you receive a clearance certificate. Where the quote can't anticipate hidden damage, we itemise a provisional sum upfront so you know the ceiling on that risk before you sign.
