Castle Hill is a suburb of big family homes on big blocks, and the bathrooms are usually generous, which opens up what's possible. A lot of the housing is two-storey brick from the 1990s and 2000s, with a main bathroom upstairs and an ensuite off the master, and after twenty-odd years owners are ready to replace the builder-grade vanities, the worn shower bases and the dated tiling. The older pockets near the showground have homes from earlier decades with smaller, more original bathrooms that need a full rethink. Because many of these are upper-storey bathrooms, waterproofing and proper drainage falls really matter, since a leak upstairs ends up in the ceiling below. We plan for that from the start. We've been renovating bathrooms across the Hills District for 12 years, and we run one team that handles demolition, plumbing, waterproofing, electrical, tiling and the fit-off, so there's no chasing five separate contractors. We give you a fixed-price quote before we start, hold the price, and finish most bathrooms on site in around three weeks. We're a licensed NSW contractor, number 383725C, based in Liverpool and working right across Castle Hill. From the first measure to handover you deal with the same people, and we plan the waterproofing around the upstairs bathrooms so common in these homes.
We come to your Castle Hill home, measure the bathroom or ensuite, check the plumbing and drainage, and talk through what you want. Then we give you a fixed-price quote that lists every fixture, tile and trade. No loose allowances, and the price holds unless you change the scope.
Once you approve the quote, we lock in the layout and finishes so nothing changes mid-job. We strip the old bathroom back, sort framing and floor falls, then waterproof to AS 3740. For upstairs bathrooms we're especially careful with the membrane and falls, and let it cure fully before tiling.
Plumbing rough-in, electrical and tiling run in the right order because one team controls the lot. No idle days waiting on a subbie. We keep the site clean and protect floors and stairs on the way through, which matters in a two-storey family home.
We fit the vanity, toilet, tapware, screen and accessories, test everything works, and tidy up. You get a final walk-through, your waterproofing certificate and compliance paperwork, and a bathroom ready to use the day we finish.
Most Castle Hill bathrooms land between $15,000 and $45,000. A cosmetic refresh, keeping the layout and updating tiles, vanity and tapware, starts from around $8,000. A full gut, where we strip back to the frame, move plumbing and rebuild, generally runs $25,000 to $45,000 depending on room size and fixtures. Castle Hill homes often have larger main bathrooms and double-vanity ensuites, so there's more area to tile and fit out, which can push a job toward the upper end. We give you a fixed-price quote up front that itemises every fixture and trade, so you know the number before we start and it won't move unless you change the scope.
Most bathrooms are finished on site in around three weeks. That covers strip-out, plumbing rough-in, waterproofing and its cure time, tiling, then the fit-off and final clean. The waterproofing membrane has to dry fully before tiling, and for an upstairs bathroom we're especially careful there, so we don't rush it. Because one team runs the whole job, the trades follow each other with no dead days. If we're doing both the main bathroom and the ensuite, we'll talk through staging so the household always has one bathroom working. You get a realistic schedule with your quote and updates as the job moves along.
Yes. Waterproofing is where most bathroom problems start, and in a two-storey Castle Hill home an upstairs leak ends up in the ceiling below, so we treat it as the critical stage. We waterproof to the NSW standard AS 3740, apply the membrane correctly across floors, walls and the shower area, get the drainage falls right, and let it cure fully before tiling. You get a waterproofing certificate at handover. For freestanding homes, internal bathroom renovations generally don't need council approval, but if your job involves moving walls or structural change we'll tell you what's required and handle the paperwork.
We're a family-run business that's been renovating bathrooms across the Hills District for 12 years, and we're a licensed NSW contractor, number 383725C. The key advantage is one team handles the whole job, from demolition through to the final silicone, so you're not coordinating a plumber, a tiler, an electrician and a waterproofer and hoping they turn up in order. We quote a fixed price, hold it, and finish most bathrooms in around three weeks. We understand the upstairs bathrooms and double-vanity ensuites common in Castle Hill homes and plan the waterproofing accordingly. You deal with the same people from the first measure to the final handover.
