A customer once called us worried she’d measured her bathroom wrong. She’d bought a floor-standing vanity for a small ensuite, got it home, and realised there wasn’t enough room to open the door without hitting the shower screen. A wall hung vanity unit would have solved the whole problem — but nobody had told her that was an option until she’d already unpacked a box on her lounge room floor.
If you’re renovating a bathroom, especially a smaller one, a wall hung vanity unit is worth understanding properly before you buy. It’s not just a style choice. It changes how the room feels, how easy it is to clean, and how much storage you actually get for the wall space you’ve got.
What “wall hung” actually means
A wall hung vanity unit is fixed straight to the wall with brackets or a rail system, with no legs or plinth touching the floor. The whole cabinet floats. That gap underneath is the whole point — it makes a small bathroom look bigger, it’s easier to mop under, and if you’ve got a mop bucket or bin you want tucked out of sight, there’s usually enough clearance for it.
The trade-off is that it needs a solid wall to hang from. Stud walls with plasterboard need proper anchors rated for the cabinet’s weight plus whatever you’ll load into it — towels, hairdryers, cleaning products, the lot. If you’re not confident with a stud finder and a spirit level, this is one job worth handing to a plumber or handyman doing the install anyway.
Why 900mm is such a common size
Vanity units come in everything from 450mm for a tiny powder room up to 1500mm+ for double basins. But 900mm sits in a sweet spot for a lot of Australian bathrooms — it’s wide enough to give you real bench space and two drawers or a door with internal shelving, without eating into the room the way a 1200mm unit would.
Our 900mm Wall Hung Vanity Unit is built from engineered timber with a pine frame, which gives it more resistance to bathroom moisture than raw solid timber while still keeping that warm, grain-visible look instead of a flat laminate finish. It’s a good middle ground if you want something that looks a bit more considered than a basic white box, but you’re not chasing a full stone-and-brass renovation.
Measuring before you order
- Check the wall width between any side fittings — toilet roll holders, towel rails, door swing — not just the wall itself.
- Measure from the finished floor level, not the subfloor, if tiling hasn’t gone down yet.
- Confirm your existing plumbing (or planned plumbing) lines up with the basin and tap holes on the unit you’re choosing.
- Leave at least 200mm of clearance below the cabinet if you want it to actually read as “floating” rather than sitting low.
Timber, oak-look and steel — what’s actually different
Most wall hung vanities fall into a few finish categories, and it’s worth knowing what you’re getting for your money.
Engineered timber with a pine substructure (like the 900mm unit above) tends to have a warmer, more natural look and holds up well if the bathroom is ventilated properly — meaning you run the exhaust fan or open a window after showers, not leave it closed up and humid all day.
Oak-look finishes over engineered board, like our 915mm Wall-Hung Cabinet in Oak and White, give you a two-tone look that suits both a modern coastal bathroom and a more traditional weatherboard home. The white base keeps it from looking too heavy on the wall, which matters in bathrooms without much natural light.
If you want something with a slightly more industrial or Japandi feel, a steel-framed option like the Wall Mounted Basin Shelf with steel frame and oak wood shelf works differently again — it’s more open shelf than enclosed cabinet, so it suits people who want their towels and products visible and accessible rather than hidden behind doors. Good for a guest bathroom where you want quick access, less ideal if you’ve got kids and need everything out of reach.
Weight limits and what you can actually store
This is the bit people skip and then regret. Every wall hung vanity has a maximum load rating, and it’s not just about the basin sitting on top — it’s everything you put inside and on the bench too. Overloading a drawer with wet towels, a hairdryer, straightener and a stack of bottles day after day is exactly how brackets work loose over a year or two.
A rough rule of thumb: keep heavier items like hairdryers and straighteners in the lower drawer closest to the wall bracket, not the top one, and don’t stack anything heavy on the open bench if the unit is rated for light use only. If you’re unsure of a specific unit’s rating, check the product listing or ask before you install — it’s a five-minute question that saves a re-hang later.
Basin styles that pair with a wall hung unit
Some wall hung vanities come basin-included, others are cabinet-only and expect you to choose your own basin separately. Check this carefully before ordering tapware, because a semi-recessed basin needs different bench cutouts to a fully countertop-mounted one.
The 915mm Oak and White unit comes with the basin already matched to the cabinet, which takes one decision off your plate if you’re renovating on a deadline and don’t want to be measuring cutouts against three different basin brands.
A quick note on assembly and installation
Most flat-pack wall hung vanities arrive with the carcass pre-built or close to it, needing doors, handles and legs (if any) attached. The part that actually takes skill is the wall fixing — locating studs or using the right wall anchors, getting the unit level, and making sure the plumbing lines up before you tighten everything down. Budget for a tradesperson for that part even if you’re happy assembling flat-pack furniture yourself. It’s the difference between a vanity that stays solid for ten years and one that starts sagging at the front after twelve months of daily use.
If you’re only replacing a vanity and not moving plumbing, existing tap and drain positions will often dictate your basin choice more than the other way around — worth checking before you fall in love with a particular style online.
