Bathroom layout guide: vanities, clearances and lighting
The quick answer
Choose a vanity 32–36 in (80–90 cm) high, keep the toilet's center at least 15 in (38 cm) from walls or fixtures on each side (18 in (45 cm) is more comfortable), and leave 30 in (75 cm) of clear space in front of it. Light a mirror from the sides at about face height.
Bathrooms are small, so a few inches matter. The figures below are common planning guidelines; plumbing, electrical and waterproofing rules vary by country and region, so always check local codes and use licensed trades for that work.
Vanity and mirror
- Vanity height: 32–36 in (80–90 cm). Taller "comfort height" vanities suit most adults.
- Mirror: roughly the width of the vanity or slightly narrower, with its center near the eye level of the main users.
- Space in front of the vanity: about 30 in (75 cm) of clear floor.
Toilet clearances
| Space | Common minimum | Comfortable |
|---|---|---|
| Toilet center to side wall or fixture | 15 in (38 cm) | 18 in (45 cm) |
| Clear space in front of toilet | 21 in (53 cm) | 30 in (75 cm) |
Showers
A shower of at least 36 × 36 in (90 × 90 cm) is comfortable for most people; smaller sizes exist but feel cramped. Allow space for the door to swing open, or choose a sliding or fixed glass panel.
Towel bars and hooks
Hang towel bars about 48 in (120 cm) from the floor and hooks a little higher. Place them within reach of the shower or bath.
Lighting a bathroom mirror
Overhead light alone casts shadows on your face. Mount wall lights on both sides of the mirror at about 60–66 in (150–170 cm) high, or use a light above the mirror plus a bright overhead light. Neutral to warm white (3000–3500 K) shows skin tones accurately. Use fittings rated for bathroom use.
