Castlecrag 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 Castlecrag and the wider Willoughby City Council area for over 20 years.
Local homeowners are increasingly choosing to renovate rather than move. Popular upgrades include modernising outdated layouts, improving storage, adding better lighting, and creating more functional spaces for families and busy professionals.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.

If you are weighing up a bathroom renovation in Castlecrag, the useful first question is not what it costs but what it involves. Moving a toilet or shower changes the plumbing and the price; keeping fixtures where they are keeps both contained. We set out both options when we quote in Castlecrag.
Design Direction
Running tile the full height of the walls has become the default in Castlecrag 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.
A growing number of Castlecrag 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.
You get documentation. Every Castlecrag bathroom we waterproof is completed to AS 3740 by a licensed applicator, photographed at membrane stage, and warranted for 20 years. Waterproofing is covered before tiling for a reason - once tiled, nobody can verify what is underneath.
Only when the existing layout genuinely fails - a door fouling the vanity, a shower too tight to use, poor circulation. Moving fixtures means new drainage, which adds cost. Where the layout is already sound we will tell you to keep it and put the budget into finishes instead.
It happens, particularly in older Castlecrag homes - rotted substrate, failed previous waterproofing, or pipework that should not be reused. We stop, show you what has been found, and price the remedy before continuing. Nothing is added to your invoice without you agreeing to it first.

Also Popular in Castlecrag
Lifting the vanity off the floor is one of the highest-value changes available in a smaller Castlecrag bathroom. Seeing the floor run underneath makes the room feel materially larger, and it removes the sealed junction at the base of a floor-standing unit where water collects. Pairing it with an in-wall cistern recovers around 200mm of projection from the toilet. Both need framing and rough-in planned before wall sheeting, so the decision has to be made early rather than at fit-off.
We inspect your Castlecrag bathroom before quoting rather than pricing from photographs or a room size. That means checking where the drainage runs, whether the floor is slab or timber, the condition of the substrate where it is visible, and how the room is ventilated. The quote that follows is fixed and itemised line by line, so you can see what each element costs and adjust scope deliberately instead of negotiating a lump sum.
Three distinct Castlecrag projects get called "a bathroom renovation". A refresh keeps the layout and replaces surfaces and fittings. A rebuild strips to frame and starts again in the same footprint. A reconfigure moves fixtures or walls. Cost roughly steps up at each stage, and so does what you get. We price the options that make sense for your room so the comparison is real.
