Castlereagh is a well-established Sydney suburb with a strong community feel and a diverse mix of housing styles. Many homes in the area were built between the 1960s and 1990s, alongside newer infill developments. Unique Bathrooms has been transforming bathrooms across Castlereagh and the wider Penrith City Council area for over 20 years.

Popular upgrades include modernising outdated layouts, improving storage, adding better lighting, and creating more functional spaces for families and busy professionals. Whether you’re after a budget-friendly refresh or a complete luxury renovation, our team delivers exceptional results on time and on budget.

Homeowners across Castlereagh tend to call us at the point where patching stops working - regrouting that will not hold, a shower base that stays damp, a vanity that no longer suits how the household uses the room. A full Castlereagh bathroom renovation resolves the cause rather than the symptom.
Design Direction
Removing the shower hob is one of the clearest current directions in Castlereagh bathroom design. A flush threshold with a linear channel drain looks considerably cleaner, removes the step that becomes an obstacle as people age, and lets the floor tile run uninterrupted across the room. It demands accurate falls set into the screed and a properly detailed membrane, which is precisely why it is worth having done by a team that waterproofs to a 20-year warranty.
A growing number of Castlereagh homeowners are renovating with the next twenty years in mind rather than the next five. A curbless shower, blocking behind the walls for grab rails to be added later, a bench seat, and lever tapware cost very little extra during the build and are disruptive and expensive to retrofit. None of it needs to look clinical - most of these choices now read simply as good contemporary design.
The structural work is identical - the same waterproofing, the same standard of plumbing and the same warranty. What changes is the fixture and finish specification: tile format and origin, tapware finish and cartridge quality, vanity construction, and screen type. We do not reduce the parts that determine whether a Castlereagh bathroom lasts.
Most Castlereagh clients do, provided there is a second bathroom available. The room itself is unusable for the duration and there are noisy days during strip-out and tiling. If it is the only bathroom in the house we will talk through the sequencing options before we start.
Compare inclusions, not headline numbers. Check whether waterproofing is specified to AS 3740, whether the quote is fixed or an estimate, whether fixtures are itemised or a provisional allowance, and what happens if damage is found. A cheaper Castlereagh quote that excludes the unknowns is not cheaper by the end.

Running tile the full height of the walls has become the default in Castlereagh renovations rather than the upgrade it once was. It removes the painted strip above the tile line that always dates first and is the first thing to show moisture damage. Large-format porcelain in 600x1200 reduces grout lines dramatically, which makes a small bathroom read as larger and cuts cleaning noticeably. The trade-off is substrate preparation - big tiles are unforgiving of walls that are out of plane, so the sheeting has to be right before tiling starts.
The difference between a good and an average Castlereagh bathroom is usually visible only at fit-off. Tiles cut to land symmetrically at corners and niches. Silicone lines that are straight and the right colour. Waste and tap holes drilled centrally. Grout colour chosen to suit the tile rather than defaulting to white. None of it costs materially more, all of it is a function of care, and collectively it is what people notice without being able to name.
People expect tiling to be the long part of a Castlereagh renovation, but the schedule is usually decided by strip-out discoveries and waterproofing cure time. Strip-out takes one to two days and tells us whether the substrate is sound. Rough-in and sheeting take several more. The membrane then needs to cure properly before any tile is laid - compressing that is the single most common cause of a bathroom failing early.
