The item most likely to be genuinely finished
Most of a twenty-year-old Hills bathroom is dated rather than broken. The vanity is often the exception.
Builder-grade units are chipboard carcasses with a cut-out around the waste trap. Over two decades that cut-out takes moisture, and the base swells from the inside while the doors and top still look serviceable. By the time it is visible, the carcass is past repair.
So of everything in the room, this is the piece where replacement is least discretionary — and fortunately it is also where an upgrade shows most.
Wall-hung, almost always
Mounting the vanity off the wall with the floor tiled continuously underneath does three things.
The room reads larger, because you can see more floor. Cleaning becomes trivial rather than a weekly negotiation with a kickboard. And you remove the floor-to-cabinet junction entirely — which is the thing that destroyed the unit you are replacing.
The requirement is wall framing that can carry the load including someone leaning on the bench. That means noggins go in at rough-in, weeks before the vanity arrives. If wall-hung is in the brief, it has to be in the brief early.
Drawers, not doors
Under a basin, doors give you a dark cupboard with a waste trap in the middle and everything useful pushed to the back. Drawers — particularly a U-shaped drawer running around the trap — give the same volume in a form you can see into.
In a family house this is not a refinement, it is the difference between storage that gets used and storage that accumulates.
Soft-close runners are standard now. Beyond that the useful additions are internal dividers and a shallow top drawer for the small items that otherwise colonise the bench.
Doubles, and whether you need one
A double basin is the default request in a four-bedroom house, and it is not always the right answer.
Two basins need roughly 1500mm of vanity to work properly. Below that you get two small bowls and almost no usable bench, which is worse than one basin with a generous run beside it.
If the room takes 1500mm, a double is genuinely useful in a household with teenagers. If it does not, a single basin with real bench space serves better — and you can put the saved money into drawers.
Mirror cabinets
A mirror cabinet adds meaningful storage without consuming any floor, which in a project-home bathroom is close to free.
Two considerations. Depth — a very deep cabinet feels imposing over a shallow vanity. And lighting: a single downlight in the ceiling behind you puts your own shadow on your face. Light at or beside the mirror solves it, needs a cable at rough-in, and is one of the few upgrades that changes the room every single morning.
Where the room allows, a full-height cupboard is the other high-value addition. Towels and spare stock do not fit under a basin, and a household with nowhere to put them stores them somewhere worse.
Matching basin, tap and bench
Three components that have to agree and are usually chosen separately.
A vessel basin sitting on the bench looks striking and raises the effective height by 100mm or more — good for tall households, irritating for short ones. An under-mount gives an uninterrupted bench that wipes clean in one pass. An integrated top removes the junction entirely and is easiest to maintain.
The tap has to suit. A wall-mounted spout needs its position and projection set at rough-in, weeks before anyone sees the basin — get it wrong and the water lands on the rim. A bench-mounted tap needs a spout height matched to the basin depth or it splashes.
None of this is expensive to get right and all of it is expensive to fix afterwards.
Materials
Engineered stone and porcelain tops handle the bathroom cycle well. Timber needs an owner who will maintain it. Laminate is good value provided the cut-out and edges are sealed.
Carcasses should be a moisture-resistant board at minimum — which is precisely the specification the original builder skipped.
Matching joinery across two rooms
Worth thinking about if the main bathroom and the ensuite are being done together, which in a Hills house they often are.
Using the same door profile, handle and benchtop across both rooms costs nothing extra — the joiner is already setting up — and it makes the house read as considered rather than renovated piecemeal. It also simplifies the order.
What should differ is the configuration. The ensuite usually wants a slimmer unit and more drawers; the main bathroom wants more bench and often a double basin. Same language, different sentence.
Where it sits
Fit-off items, installed after tiling in a full renovation, but specified much earlier because the rough-in has to suit them.

Questions people ask before they commit
Why do builder-grade vanities fail first?
Chipboard carcasses with a cut-out around the waste trap absorb moisture at the base over years. The doors and the top usually look fine while the carcass is quietly swelling. It is the single item in a 2000s bathroom most likely to be past repair rather than merely dated.
Wall-hung or floor-standing?
Wall-hung for most rooms. The floor runs underneath so the room reads larger, cleaning becomes trivial, and you remove the kickboard junction where water sits. It needs wall framing that can carry the load, which has to be sorted at rough-in rather than at fit-off.
Custom or off-the-shelf?
Off-the-shelf suits most Hills bathrooms well, because project-home rooms are usually built to standard dimensions. Custom earns its cost where the room is an odd width, where you want a double basin in a space that does not take a standard one, or where the vanity continues into other joinery.
How much storage does a family house need?
More than the showroom display suggests. Drawers beat doors because you can see what is at the back. A mirror cabinet adds usable volume without taking floor. Where the room allows, a tall cupboard holds the towels and spare stock that a vanity never fits.
What benchtop lasts best?
Engineered stone and porcelain both handle the wet-and-dry cycle well. Timber looks superb and needs maintenance. Laminate is fine value provided the basin cut-out and edges are sealed properly — that junction is exactly where laminate fails.
