Bathroom Vanity Basics: Choosing the Right Size and Basin Style

Not sure which kind of vanity will actually work in your bathroom? Between the width of your room, how many people share it, and your budget, there’s a lot that goes into finding the one that is a good match for your space.

Choose Your Bathroom Vanity Size

Selecting the right vanity size sets the foundation for your bathroom layout. Smaller sizes maximise floor space in powder rooms and ensuites, while larger configurations add storage and luxury to master bathrooms.

1800mm Vanities

The 1800mm remains a top pick for master ensuites and bigger bathrooms where space isn’t an issue. You can choose between single or dual sinks, but going with dual sinks gives your bathroom a real luxury feel. Just leave at least 900mm clear in front and make sure your wall can handle the weight if you’re going for a wall-mounted option.

1500mm Vanities

For couples with a larger bathroom, a thoughtfully designed 1500 bathroom vanity with a double-basin setup completely transforms the morning routine by providing both individuals with their own dedicated basin and personal grooming station. This specific width strikes the perfect balance: it offers expansive counter space (typically around 50 to 60cm per person) and generous under-bench drawer storage without overcrowding the room’s floor plan.

Beyond speeding up shared mornings, 1500mm vanities help keep toiletries organised and separate, while adding a luxurious, high-end feel that boosts overall home value. Just be sure to measure clearance carefully around your toilet, shower door swings, and walkways so traffic flows smoothly. It is also essential to check your plumbing rough-in locations to confirm waste and supply lines match a double-outlet setup before committing to a 1500mm vanity unit.

1200mm Vanities

A 1200mm vanity is a great middle ground for couples who want more storage without needing a huge wall. Some of these vanities even fit two basins in a smaller footprint. Just double-check your door swings and drawer clearance before you make a purchase.

900mm Vanities

A 900mm vanity is the most popular pick for the standard family home, since it balances storage with a footprint that won’t take over the room. For comfortable use, aim to have 800-900mm of clear floor space in front of it. And if your bathroom is on the narrower side, opt for a wall-hung vanity.

750mm Vanities

A 750mm vanity suits guest bathrooms or one person’s daily routine nicely. It gives you a bit more bench space than the smaller sizes without compromising on movement area. To see if it fits well, check that all drawers and doors have enough room to open fully without hitting anything.

600mm and 465mm Vanities

When you’re working with a tight space, a 600mm or 465mm vanity is the way to go. The 600mm size still has enough room for one person’s daily essentials, while the 465mm works best in powder rooms or narrow corners where every centimetre counts. Both keep the room feeling open, so pair them with wall storage if you need additional space for your bits and pieces.

There is no such thing as a best vanity size. You just have to go with the one that matches how you actually use your bathroom. Once you’ve got your size sorted, the rest of the design comes together a whole lot easier.

Single vs. Double Basin Vanity

Once you know your overall width, decide whether a single or double basin vanity best suits your daily routine and budget.

Benefits of a Single Sink Vanity

A single sink vanity is a compact option and easier on your budget. It also leaves more floor space open in smaller bathrooms. If you live alone in a big house, you can still opt for a 1500mm vanity featuring a single bowl, which will fill the space without needing two separate basins.

With just one tap and one drain, the plumbing stays simple and often fits existing setups without any trouble. It’s also much easier to keep tidy, since you’re only managing clutter around one basin instead of two.

Benefits of a Double Sink Vanity

A double basin vanity lets two people use the space at the same time, giving each person their own area for toiletries. This cuts down on morning bottlenecks and keeps shared bathrooms running smoothly.

Which One Should You Choose

If your bathroom has the space, a double basin vanity is often the better long-term option for families or couples. It costs more upfront, but the convenience and storage make it worth the investment. If you plan on selling the house at some point, it can boost your value as well.

For individuals working with a smaller footprint or a tighter budget, a single basin vanity still gets the job done, saving you space and money while keeping things clean and functional.

Takeaway

The right vanity comes down to what fits your space and how you actually use it, not what looks good in a showroom. Whether you’re after a more compact 600mm option or a spacious 1500 bathroom vanity, get your measurements sorted first, and the rest of your bathroom design will fall into place from there.
