A vanity unit can look fine on a plan and still feel awkward once drawers, doors, radiator valves and the bathroom door are considered. Measure the room as a route, not just a wall.
If you move the basin position, check the hot and cold supply, the waste route and the fall on the waste pipe before committing to a unit.
Bathroom vanity depth guide
| Unit type | Typical depth | Best use |
|---|---|---|
| Slim cloakroom unit | 250-350mm | Small WC or narrow room where projection matters. |
| Standard basin vanity | 400-500mm | Most family bathrooms and en-suites. |
| Deep storage unit | 500mm+ | Larger rooms where drawers and worktop space matter. |
| Wall-hung unit | Varies by product | Can make floor cleaning easier but needs solid fixing. |
| Worktop basin setup | Depends on basin and worktop | Check tap reach, splash and total height. |
