Double Vanity Buying Guide


A double vanity is one cabinet and top with two basins, so two people can use the bathroom at the same time. This collection includes wall hung and floor standing double vanities from ADP, Timberline, Marquis, Ingrain and Otti. It suits master ensuites and busy family bathrooms where the morning queue is a daily problem.

Is a double vanity worth it?

A double vanity is worth it when two people regularly need the bathroom at the same time and the wall is wide enough. Each person gets their own basin and bench space. It is less useful in a narrow room or a bathroom mostly used by one person, where a single basin on a wide top gives more uninterrupted bench space and simpler plumbing.

How wide does a double vanity need to be?

Double vanities usually start at 1200mm, which is the minimum that works. At that width the bowls sit close together and the bench between them is small. A width of 1500mm is a comfortable starting point for two people using it every day, and 1800mm gives each person more elbow room and some bench space between the bowls. Allow clearance for doors, the toilet and the shower entry before settling on a width.

Should I choose a wall hung or floor standing double vanity?

Most double vanities here are wall hung, such as the ADP Clifton, Marquis Cove and Pier, Ingrain Grooved and Otti Bondi. A wall hung unit shows more floor, which makes the room feel larger and easier to clean, but the wall needs solid framing for a long, heavy cabinet. Floor standing options, such as the Timberline Nevada with an Alpha ceramic top, take their weight through the floor and usually give more storage.

What top suits a double vanity?

Choose between a top with built-in basins and a stone top with separate basins. The ADP Glacier Lite twin vanities come with a ceramic or cast marble top that includes both bowls, which keeps cleaning simple. The Otti Byron and Timberline Nevada come with stone or SilkSurface tops for above counter basins, so you choose the basin shape.

What plumbing does a double vanity need?

Each basin needs its own waste and a tap, so plan two sets of water and drainage points. The wastes can sometimes share one outlet in the wall through a combined fitting, which your plumber can advise on. Set the plumbing positions from the vanity's specification drawing at rough-in, so the pipes line up with the basins and clear the drawers.

What finish and style should I choose?

Match the vanity style to the room. The Ingrain Curved Fluted and Contoured Ash, and the Otti Bondi curve, have soft shapes and timber textures. The ADP Clifton and London have a more classic panel look. A long double vanity is a large surface in the room, so a timber look adds warmth while a white or pale finish keeps the space light.

Completing the room

Hang two matching mirrors, such as round mirrors or arched bathroom mirrors, one above each basin. For single-basin floor units, see freestanding vanities at The Blue Space.

Frequently Asked Questions

What is a double vanity?

A double vanity is one cabinet and top fitted with two basins, so two people can use the bathroom at the same time. It is a layout, not a fixed size, and double bowls start at 1200mm in some of our ranges and 1500mm in most.

What are the drawbacks of a double vanity?

You need more wall width, the plumbing doubles to two water supplies and two wastes, and the second basin takes some bench space and sometimes drawer depth. A single basin on a wide top leaves more bench and a simpler set of pipes.

Are double vanities a good idea?

They suit a room where two people use the bathroom at the same time and the wall is wide enough, such as a master ensuite or a busy family bathroom. In a narrow room, or one that two people rarely share, one basin with more bench space is usually the better choice.

What is the standard size of a double vanity in Australia?

Double vanities usually come in 1200mm, 1500mm and 1800mm widths, with 1200mm the minimum that works, 1500mm the comfortable starting point and 1800mm giving the most room. Depth is usually about 450mm to 550mm.

Does each basin in a double vanity need its own tap?

Yes, each basin needs its own tap and its own waste, so choose the tapware early and check the tap hole count before you order. Basins, wastes and mixers are often sold separately.

Can I replace a single vanity with a double vanity?

Often yes, if the wall is wide enough, but expect a second water supply and waste. Have a licensed plumber assess the existing pipes before you order.
