Plan three layers — ambient, task, and accent — with task sconces flanking the mirror at eye level.
One ceiling fixture shadows your face every time you lean in to shave or apply makeup. Sketch a layered plan before buying: ambient for the room, task at the mirror, dim accent for 3 a.m. trips. This guide covers placement heights, illuminance targets, shower-rated fixtures, and code caveats.
Plan Three Light Layers, Not One Fixture
A typical bathroom needs ambient, task, and accent layers, each on its own control. Ambient handles overall brightness, task kills facial shadows at the mirror, and accent adds night navigation and depth.
Worked example for a 5-by-8-foot bathroom: two 4-inch recessed LED downlights on a dimmer for ambient, spaced 4 feet apart and 2 feet from walls, plus vanity sconces. The shower gets its own 4-inch recessed LED rated for wet locations, centered over the footprint.
Vanity sconces: 7-watt LED lamps at 2700K with CRI 90 or higher flatter skin tones and render makeup colors accurately; warm white reads calmer at night than cool white.
Where to Mount Vanity and Mirror Lights
Flank the mirror with sconces or bars on both sides at roughly eye level — not overhead — so light hits the face evenly. This is the highest-impact correction in most bathroom remodels.
- Height: planning guides place vanity lights at 60–65 inches or 60–66 inches above the floor; one manufacturer puts the fixture centerline at 72 inches.
- Spacing: side sconces about 36–40 inches apart, straddling the mirror.
- Ambient: dimmable recessed LED downlights or a ceiling fixture on a wall switch.
- Accent: toe-kicks, coves, niches, or under a floating vanity for night navigation.
Match fixture height to your tallest regular user, then split the difference if two people share the mirror. Sconces beat a single overhead bar because they light the face from two angles instead of straight down.
How Bright Should Each Zone Be?
Illuminance targets separate a well-lit bathroom from one that merely looks bright. The mirror is where most bathrooms fall short.
| Zone | Target Illuminance | Fixture Note |
|---|---|---|
| General ambient | 150–300 lux | Dimmable recessed LED downlights |
| Mirror / vanity | 300–500 lux | Sconces flanking at eye level |
| Shower interior | 150–200 lux | Wet-location-rated recessed LED |
| Toilet area | 100–150 lux | Small recessed or wall fixture |
| Accent / night | 20–50 lux | Toe-kick or cove strip, dimmed |
Code, Zones, and Mistakes That Wreck a Layout
Luminaires near tubs and showers must meet local electrical code and fixture listing requirements, with wet-location-rated fixtures in the shower zone. NEC section 410.10(D) governs tub and shower areas, and
Zone-based planning — mapping the room into Zones 0 through 3 before buying — determines which fixtures qualify, where wiring runs, and where drivers live. Switches, drivers, and dimmers belong outside water exposure zones.
The repeat offenders:
- A single ceiling light, leaving the face shadowed at the mirror.
- Mounting lighting only above the mirror instead of flanking it at eye level.
- Ignoring bath and shower zone boundaries, then buying unrated fixtures.
- Skipping dimmers on ambient and accent layers, ruining night-time comfort.
- Not confirming receptacle, circuit, and GFCI requirements alongside the lighting plan.
A City of Los Altos bathroom remodel handout covers the electrical coordination side well — worth reading before your electrician visits. To skip the guesswork, this roundup of tested bathroom LED light picks matches fixtures to each layer.
Fixture listings for tub and shower zones come from the electrical code itself: NEC 410.10(D) luminaire requirements spell out what’s permitted in wet areas.
Draft the Layout Brief Before You Shop
A one-page layout brief prevents most buying mistakes: room dimensions, ceiling height, bath/shower/vanity locations, zone plan, target illuminance per zone, color temperature, CRI, dimming requirements, switch positions, driver locations, and budget. A scaled floor plan drawn from those notes tells you how many fixtures each layer needs — and stops you overspending on lights that fight each other.
FAQs
Should bathroom vanity lights go above the mirror or beside it?
Beside it. Flanking sconces at eye level light the face from two sides and eliminate shadows a single overhead fixture casts. If you must use an overhead bar, pair it with side lighting. Planning guidance commonly recommends sconces or bars on both sides of the mirror rather than overhead alone.
What color temperature works best for bathroom LEDs?
2700K with a CRI of 90 or higher is standard for vanity lighting. Warm white flatters skin tones and renders makeup colors accurately, while high-CRI lamps keep colors true. Cooler temperatures suit utility areas but read harsh at the mirror, especially in the morning.
Do shower lights need a special rating?
Yes. Fixtures inside the shower zone need a wet-location listing, not just damp-rated. NEC section 410.10(D) governs luminaires near tubs and showers, and local rules can add requirements. Confirm ratings before purchase — returning an installed fixture costs far more than choosing correctly the first time.
