How wide should a bathroom mirror be over the sink?
The mirror should not be wider than the vanity. Ideally it matches its width, or is 2 to 4 in (5 to 10 cm) narrower on each side. Over a double vanity, you have two options: one large bathroom wall mirror across the full length, or two round or oval mirrors, each centered on a faucet.
| Vanity | Recommended mirror |
|---|---|
| Powder room sink 16 to 20 in (40 to 50 cm) | 12 to 16 in (30 to 40 cm) round |
| 24 in (60 cm) | 20 to 24 in (50 to 60 cm) wide |
| 31 in (80 cm) | 28 to 31 in (70 to 80 cm), e.g. a 31 × 24 in (80 × 60 cm) mirror |
| 35 to 39 in (90 to 100 cm) | a 35 in (90 cm) bathroom mirror, or a 31 in (80 cm) round |
| Double vanity 47 to 55 in (120 to 140 cm) | 47 in (120 cm), or two mirrors of 24 to 31 in (60 to 80 cm) |
For height, leave 6 to 10 in (15 to 25 cm) between the top of the faucet and the bottom of the glass, and place its center at about 63 in (160 cm) from the floor. If people of very different heights share the bathroom, a tall vertical mirror or an oval works for everyone.
