Bathroom vanities typically have a standard depth ranging from 20 to 21 inches (about 50 to 53 cm), which balances storage space and user comfort. For smaller bathrooms or powder rooms, shallower vanities with depths around 16 to 18 inches are common to maximize floor space while still providing basic storage. Some larger or luxury bathrooms may have deeper vanities up to 24 inches to allow for extra storage. In summary:
- Standard depth: 20–21 inches (most common)
- Compact/shallow depth: 16–18 inches (for small or narrow bathrooms)
- Extended depth: up to 24 inches (for larger bathrooms with greater storage needs)
This depth range ensures vanities provide adequate countertop space and storage without overwhelming the bathroom space or hindering movement.
