Double Basin Vanity Buying Guide
A double vanity solves a genuinely common bathroom bottleneck: one basin serving two people's morning routines at once. Splitting that into two dedicated stations changes how a shared bathroom actually functions, not just how it looks.
Where a double vanity works best
A master ensuite is the most common application, giving each person their own basin, mirror zone and storage rather than sharing one station. A family bathroom benefits similarly, letting two children brush their teeth at once rather than queuing. A larger main or guest bathroom also suits a double vanity well: beyond the practical benefit, it gives a bigger room a genuine visual anchor, filling a long wall in a way a single, smaller vanity can't.
Choosing a vanity type
Wall-hung (floating) vanities mount directly to the wall, leaving the floor clear underneath for a cleaner, more spacious look and genuinely easier cleaning. Freestanding vanities sit on the floor, generally offering deeper drawers and greater overall storage, suited to a more traditional or classic bathroom. Custom vanities, available through Australian-made brands including Timberline, Marquis and ADP, let width, drawer layout, colour and benchtop be specified exactly, suited to an awkward space or a very specific vision.
A closer look at named ranges
ADP's Waverley, Clifton and Eli vanities, along with the Glacier Lite range in door-and-drawer trio, twin and slim configurations, span a genuinely wide selection of finishes and benchtop materials. Ingrain's Curved Fluted, Grooved and Contoured Ash vanities bring Australian timber craftsmanship and genuine textural detail. Marquis's Cove, Pier, Bay, Lake and Arco ranges are Australian-made, each with distinct proportions. Timberline's Nevada, Nevada Plus, Nevada Classic and Indiana ranges pair with Alpha ceramic, SilkSurface or Regal acrylic tops. Otti's Byron, Bondi and Hampshire ranges bring curved and fluted detailing across natural oak, black oak and white finishes.
Choosing a material and finish
Timber vanities, including Ingrain's range, bring genuine warmth and natural grain variation, suited to a coastal, rustic or contemporary bathroom alike. White vanities remain a versatile, adaptable choice that lets tile, tapware and towel colours take the lead. Curved and fluted designs, Otti a strong reference point here, bring genuine textural interest and a more bespoke, architectural feel. Hamptons-style vanities, with shaker-style doors, suit a relaxed, coastal-elegant bathroom.
The practical benefits of a double vanity
Two basins mean two people can get ready simultaneously, a genuine time saving on a busy morning. The doubled storage, more drawers, more cupboards and more benchtop space, means less clutter and a genuinely more organised room. A double vanity also gives a larger bathroom real visual weight, anchoring the space rather than leaving it feeling sparse.
Planning plumbing and layout
Moving from a single to a double basin isn't a simple swap: it requires a second set of hot and cold water lines and a second waste connection, worth factoring into the renovation budget and discussing with a plumber early in the process. A minimum of 70cm of clear floor space in front of the vanity is a sensible planning guide, checked against door swing and access to the toilet or shower.
Choosing a mirror configuration
Two individual mirrors, centred over each basin, give a sharp, symmetrical look that reinforces each person's separate zone. A single wide mirror spanning the vanity's full length can make the room feel more expansive instead. Either way, a dedicated light over each basin is worth planning for.
Drawers or cupboards?
Drawers suit smaller, frequently used items, makeup, toiletries, giving a clear view of everything at once. Cupboards suit taller or bulkier items, cleaning supplies, spare toilet paper. Most double vanities offer a mix of both, worth matching to what actually needs storing.
What width do you need for a double vanity?
A double vanity generally needs at least 1200mm of width to fit two basins with usable space between them, though 1500mm and 1800mm are more common for comfortable spacing. Below 1200mm, the basins sit too close together, so a single basin or split design usually works better in a narrower bathroom.
What sizes do double vanities come in?
Double vanities typically range from 1200mm to 1800mm wide, with 1500mm the most popular size in Australian bathrooms. Standard depth runs 460mm to 500mm, and height sits around 850mm to 900mm. This collection spans 1200mm, 1500mm and 1800mm options in both wall-hung and freestanding styles.
What is the difference between a double sink vanity and a double bowl vanity?
They describe the same thing: a single vanity unit with two separate basins, also called a double basin vanity. Some pair two distinct above-counter or under-counter bowls, while others use a moulded top with two integrated bowls. Both let two people use the bathroom at once.
Can you get a wall-hung double vanity?
Yes. A wall-hung double vanity mounts to the wall with the floor left clear underneath, making cleaning easier and suiting a modern bathroom. This collection includes 1200mm, 1500mm and 1800mm wall-hung options, in timber-look, matte black and white finishes, paired with single or twin basins.
Does a wall-hung double vanity need special wall preparation?
Yes. A wall-hung vanity must be anchored to solid structural support, ideally wall studs or a solid timber blocking frame installed within the wall cavity, since standard plasterboard alone won't support the combined weight of the cabinet, basins, benchtop and contents. Discussing blocking requirements with a builder or plumber before the walls are lined is essential for a renovation, and a licensed plumber or carpenter should carry out the installation.
What height should a double vanity be installed at?
The standard installation height in Australia is approximately 850mm from the finished floor to the top of the benchtop, adjustable to suit the household, lowered slightly for shorter users or children, or raised to around 900mm for taller adults.
What size mirror suits a double vanity?
A bathroom mirror should generally match the vanity's width, or sit up to 50mm to 100mm narrower. A 1200mm double vanity suits a 1100mm to 1200mm mirror, either as one wide piece or two individual mirrors positioned side by side.
Completing the bathroom
A double vanity is easiest to finalise once the basin and tapware direction are settled, since basin configuration and tap compatibility both depend on those earlier decisions. The Blue Space's Basin Taps and Mirrors collections are worth reviewing alongside a double vanity selection to bring the full bathroom together.
