900mm Bathroom Vanities Buying Guide
The vanity generally sets the tone for the rest of a bathroom renovation, since tiling, tapware and mirror choices all end up working around it rather than the other way round. At 900mm, this decision becomes considerably easier: the size is large enough to deliver genuine storage and bench space, but not so large that it overwhelms a typical Australian bathroom's footprint.
What is a 900mm vanity?
A 900mm vanity is a cabinet and basin combination measuring 90cm wide, generally sold as a complete unit with the cabinet and benchtop, whether ceramic, stone or timber, included together. This width strikes a genuine balance: deep enough for a proper basin without excessive splashing, while still leaving real bench space, the "landing strip" for soap, a toothbrush and daily skincare, that a narrower vanity often can't provide.
Where a 900mm vanity works well
Main family bathrooms, rarely oversized in a typical Australian home, suit 900mm well, giving both parents and children room to use the basin without the vanity consuming the entire room. Genuine drawers at this size handle spare toilet rolls, bath toys and a first-aid kit, the everyday clutter a smaller vanity can't accommodate.
A larger ensuite benefits noticeably from stepping up to 900mm from a smaller unit, giving the room a more considered, adult-focused feel rather than reading as an afterthought.
Tighter bathrooms and apartments can still accommodate a 900mm vanity using a slimline configuration, shallower from front to back, which preserves the width and storage of the size while reducing how far the unit projects into the room.
A more generous powder room benefits from 900mm as well, giving proper storage for guest towels and spare supplies rather than a bare, purely functional cloakroom vanity.
Wall hung or freestanding?
Wall-hung (floating) vanities mount directly to the wall, leaving the floor beneath fully visible. This helps a bathroom feel larger, since the eye reads the continuous floor tiling running underneath, and it simplifies cleaning considerably, since there's no cabinet base for grime to collect around. This configuration suits a modern, clean or minimalist bathroom particularly well, and ADP's Australian-made wall-hung range is worth exploring specifically for strong drawer systems at this size.
Freestanding (floor-mount) vanities sit directly on the floor, either on legs or a solid kicker base that also conceals older floor-based plumbing. The main advantage here is storage volume: full-height cabinetry suits a busy household needing to store cleaning supplies, spare towels and general household items. Freestanding vanities also carry a more grounded, substantial presence, suiting classic or Hamptons-style bathrooms particularly well, a 900mm white shaker-style vanity in particular remains a genuinely timeless choice.
Choosing a style and finish
Solid timber vanities bring genuine warmth and natural material variation to a bathroom otherwise built from tile and porcelain, with each piece carrying its own individual grain. Ingrain is a strong reference point for this material specifically.
Timber-look laminate replicates that same warmth considerably more affordably, using current technology that's genuinely difficult to distinguish from real timber at a glance, while offering better resistance to a bathroom's ongoing humidity. Timberline's 900mm range covers this finish well.
Fluted vanities bring a ribbed, textured detail to the drawer fronts, adding depth and a considered play of light and shadow rather than a flat, plain surface.
Curved vanities soften a bathroom otherwise built from hard lines and square corners, and even a subtle curved front at 900mm makes a genuine design statement without adding to the unit's actual footprint.
Classic white remains the most versatile, dependable choice, available in gloss for a bright, reflective finish, matte for a softer, more contemporary look, or a shaker-style door for a Hamptons-inspired direction. A white 900mm vanity works as a genuine blank canvas, pairing with black, brushed brass or chrome tapware and virtually any surrounding tile.
Custom options
Where 900mm is close but not quite right, or a specific colour is needed, custom vanities offer full control over cabinet colour, benchtop, basin and handles. Marquis is a strong option for this level of customisation, and Turner Hastings offers a more traditional, furniture-style alternative for a classic, considered look.
The benefits of a 900mm vanity
Storage is the standout advantage over a smaller 600mm or 750mm unit, which often means shallower drawers or a single cupboard interrupted by pipework. At 900mm, genuinely deep, wide drawers, generally two or three, hold full-sized bottles upright and let daily items be sorted properly rather than piled together.
Usable bench space follows directly from the width: a 900mm vanity accommodates a generous basin alongside real landing space for soap, a toothbrush and moisturiser, without everything balanced precariously on the basin's edge.
A genuine focal point emerges at this size too, since a 900mm vanity has enough presence to function as a considered furniture piece rather than a purely functional fitting, giving the room's mirror, lighting and tapware something substantial to be planned around.
Proportional fit for a typical Australian bathroom rounds out the case for this size specifically: large enough to deliver on storage and presence, without overwhelming the room's walkway or crowding the space around it. Measuring the room and confirming reasonable clearance on either side remains worth doing regardless of size, but 900mm tends to sit comfortably within most standard layouts without further adjustment.
Practical checks before ordering
Plumbing is the first and most important check. If the waste pipe comes from the wall, a wall-hung vanity conceals it neatly within the cabinet. If it comes from the floor, a freestanding vanity with a kicker base covers it directly. Wanting a wall-hung vanity where a floor waste already exists is possible, but requires a plumber to relocate the pipe, involving floor and wall work that adds genuine cost and time, worth knowing before committing to a specific style.
Drawers versus cupboards is worth deciding deliberately: a drawer pulled fully open shows its entire contents at a glance, while a cupboard often means reaching past pipework into a darker, harder-to-navigate space. Drawers are generally the more practical choice at this size, and a 900mm vanity with two or three genuinely deep drawers offers considerable storage.
Basin type affects both look and function. An integrated top, basin and benchtop moulded as one seamless piece, remains the most common and practical choice, with no joins or gaps to clean around. A top-mount (countertop) basin sits as a bowl on a flat benchtop, giving a more considered, spa-like look, though it needs a taller vessel mixer tap to suit. An undermount basin, fixed beneath a stone benchtop, gives the cleanest, flattest bench surface, letting crumbs and water be wiped directly into the basin. None of these is objectively superior; the choice comes down to the specific look intended for the room.
Tap placement needs deciding early, before tiling begins. A vanity top with tap holes suits a standard benchtop-mounted mixer, straightforward to install. Wall-mounted taps give a cleaner, more considered look and free up additional bench space, but require the plumbing run inside the wall in advance, a detail that can't be added after the fact once tiling is complete.
Completing the bathroom
A 900mm vanity is easiest to finalise once the basin type and tapware direction are settled, since these decisions all interact directly with the vanity's configuration. The Blue Space's Basins and Basin Taps collections are worth reviewing alongside a 900mm vanity selection to bring the full room together.
