How to choose the right 900mm vanity

900mm sits at the point where a single-basin vanity starts to feel genuinely spacious rather than just adequate. It's a common choice for main family bathrooms where the vanity gets heavy daily use from multiple household members, even if only one person is at the basin at any given time. As with 750mm, drawers are usually offset to one side of the basin — choose left or right hand based on your plumbing layout and the room's traffic flow, particularly door swing and proximity to the shower or bath.

The wider cabinet at this size generally supports two to three drawers, or a drawer-and-cupboard split, giving noticeably more storage than smaller sizes without the cost jump of a double-bowl vanity. If your bathroom is shared by two people getting ready at the same time, it's still worth comparing a 900mm single-basin unit against a 1200mm double-bowl vanity before deciding, since the latter avoids one person waiting for the basin. Confirm whether the ceramic top is included or sold separately when comparing products at this size.
