Vanity lighting specs fail in two places the style-focused retailers never mention: ADA projection limits in circulation paths and listing ratings by mounting zone. Both come up on every multifamily and hospitality job, and both are cheap to get right at order time. Start with sizing, then check the two compliance boxes before the finish schedule locks.
How to Size Bathroom Vanity Lights
For an over-mirror bar, target roughly 75 percent of the mirror width so the fixture reads centered without overhanging the glass. For side-mounted sconces, center the fixtures at eye level and flank the mirror so light reaches both sides of the face. The table gives the working numbers.
| Mirror or Vanity Width | Over-Mirror Fixture Width | Mounting Height |
|---|
| 24 in | 18 to 22 in | Center the bar 75 to 80 in above finished floor |
| 30 in | 22 to 26 in | Same |
| 36 in | 26 to 30 in | Same |
| 48 in | 32 to 40 in | Same |
| 60 in double vanity | Two smaller bars, or one 40 to 50 in fixture | Same |
| Side sconces, any mirror | Pairs flanking the mirror | Centered 60 to 66 in above finished floor, 28 to 40 in apart |
ADA Projection Limits in Circulation Paths
Wall-mounted objects with leading edges between 27 and 80 inches above the floor may project no more than 4 inches into a circulation path along an accessible route. That rule catches vanity light fixtures in public and common-use restrooms across multifamily, hospitality, and office projects, where a deep decorative sconce beside the door becomes a protruding object violation. Where the fixture sits over the vanity and outside the circulation path, deeper profiles are fine; where it borders the route, spec low-profile bodies and verify against ICC A117.1 and the ADA Standards for your project type.
Damp and Wet Listings by Mounting Zone
Check the zone, not the room. A fixture over a vanity outside the shower footprint needs a damp location listing, which most bathroom light fixtures in this category carry. Inside a tub or shower zone, where the fixture is subject to spray, the listing must be wet location. The distinction matters most on compact hotel and multifamily baths where a single bar can end up within the tub zone on the drawings. Coordinate GFCI protection for the bathroom circuit per NEC 210.8 while the electrical package is open.
CRI 90 Light for Grooming Tasks
Grooming is a color-critical task: makeup, shaving, and wardrobe checks all happen at this mirror. Spec 90+ CRI bathroom vanity lights for hotel guest baths, locker rooms, and unit bathrooms, in the 2700K to 3500K range depending on the property's design language. Placement does the rest: side sconces or a long horizontal bar spread light across the face and kill the under-eye shadows that a single ceiling point creates. Good bathroom lighting at the mirror is a guest-review line item, and it costs the same as bad lighting at spec time.
Multifamily and Hospitality Packages
Unit-count projects need one SKU family across every bath: consistent CCT, consistent finish, and a supply line that can deliver phase by phase. Send the unit count and finish schedule for a volume quote. For the adjacent families, see decorative wall sconces for the dressier profiles, wall mounted cylinders for architectural wall lighting, the parent wall sconces category, and backlit lighted vanity mirrors where the mirror and the light are one fixture.
