Bathroom Vanity Lighting Guide: How Many Lights, What Height
Posted by SARAH K.
Updated August 2026
Vanity lighting is the light you see your own face in every morning, and it is the light most bathrooms get wrong. A single ceiling fixture behind you throws your face into shadow. A bar mounted too high glares off the mirror. This guide covers the two layouts that actually work, the mounting heights to use, how many lights a given vanity needs, and what to look for in bulbs. We are Big Deals Bay, and we stock genuine Kohler bathroom lighting at well below retail, including discontinued finishes, so we spend a lot of time answering exactly these questions.
The goal: light the face, not the mirror
Good vanity lighting puts even, shadow-free light on your face at mirror height. Shadows under the eyes, nose, and chin come from light arriving from above only. The cure is light arriving from the sides at face level, or failing that, a broad soft source above the mirror that is close enough to wrap light around your features. Every layout decision below follows from that one idea.
Layout one: sconces flanking the mirror
Two wall sconces, one on each side of the mirror, is the best facial lighting you can install. Light from both sides cancels shadows instead of casting them. It is the layout makeup artists and barbers use for a reason.
- Height: center the sconces at roughly eye level, about 60 to 66 inches above the finished floor. If multiple people share the bathroom, split the difference in their heights.
- Spacing: place them 36 to 40 inches apart, or just outside the mirror edges if the mirror is wider than that.
- Shades: diffused shades in glass or fabric spread light softly. Exposed bare bulbs at eye level cause glare.
Sconces need wall boxes beside the mirror, which is easy in new construction or a remodel and harder as a retrofit. If your only existing box is above the mirror, layout two is the practical answer. For a deeper look at picking sconce styles and sizes, see our guide on how to choose bathroom sconces.
Layout two: a bath bar above the mirror
A horizontal multi-light fixture above the mirror is the most common vanity setup, and done right it works well.
- Height: mount the fixture so its center sits about 75 to 80 inches above the finished floor, typically a few inches above the top of the mirror.
- Width: the fixture should be about as wide as the mirror, or roughly three quarters the width of the vanity. A short bar over a wide mirror leaves the outer thirds of your face dim.
- Direction: shades that point down or diffuse in all directions light your face. Shades that point straight up mostly light the ceiling.
The best bathrooms combine both layouts: sconces for the face, plus a ceiling fixture for general room light. See our full guide on Kohler lighting and bathroom accessories for how the pieces fit together.
How many lights does your vanity need?
Match the number of lamps to the vanity width. These are the ranges we suggest when customers ask:
| Vanity width | Typical setup | Notes |
|---|---|---|
| 24 inches (single sink) | 2 sconces, or a 2-light bar | One sconce beside the mirror also works in a powder room |
| 30 to 36 inches | 2 sconces, or a 2- to 3-light bar | The most common size range |
| 48 inches | 3-light bar, or sconces plus a bar | Keep the bar close to mirror width |
| 60 inches (double sink) | 4-light bar, or a bar plus a center sconce, or 2 sconces per mirror | With two separate mirrors, treat each as its own station |
| 72 inches and up | Two separate fixtures or a long multi-light bar | One small fixture centered on a long vanity leaves dark ends |
Bulbs: CRI is the spec that changes your morning
Two numbers on an LED bulb box matter at the vanity.
CRI, color rendering index, measures how accurately a light source shows color compared to daylight. Standard LEDs around 80 CRI make skin look slightly flat and gray, which matters when you are checking your own color, doing makeup, or shaving. At the vanity, look for 90 CRI or higher. It is the single cheapest upgrade in bathroom lighting.
Color temperature sets warm versus cool. Around 2700K is warm and flattering, 3000K is neutral-warm and the common recommendation for bathrooms, and 4000K and up reads clinical. Whatever you choose, use the same temperature in every fixture in the room so the light does not clash.
Damp ratings and finishes
Bathrooms are humid, so vanity fixtures should carry a damp-location rating, which nearly all purpose-built bath fixtures do. Fixtures inside a shower enclosure need a wet rating, but that is a different application. Check the rating printed on the fixture label or listing.
On finish: match or deliberately coordinate your lighting finish with the faucet and hardware. We stock Kohler lighting in brushed nickel, matte black, and other finishes, including discontinued Kohler lines, which is often the only way to match hardware from a line that Kohler no longer makes.
Installation safety
Swapping a vanity fixture is a common DIY job, but it is still electrical work. Turn off the circuit at the breaker, not just the wall switch, and confirm the power is off at the fixture wires with a non-contact voltage tester before touching anything. If the wiring looks unfamiliar, if there is no ground, or if you are unsure at any step, hire a licensed electrician. A fixture swap is a small job for a pro and not worth a shock or a fire risk to guess through.
Frequently asked questions
How high should vanity lights be above the mirror?
Mount a bar fixture with its center around 75 to 80 inches above the finished floor, which usually lands a few inches above the mirror. If the mirror is unusually tall, mount just above its top edge rather than forcing the number.
Should vanity lights point up or down?
Down or diffused for face lighting. Up-pointing shades bounce light off the ceiling, which is soft but weak by the time it reaches your face. Many fixtures can mount either way; if you mount shades up, plan on the ceiling fixture doing more of the work.
Are sconces or a light bar better?
Side sconces light a face more evenly than any over-mirror fixture. The bar wins on retrofit practicality because it uses the wall box most bathrooms already have above the mirror. If you are remodeling and can run boxes beside the mirror, choose sconces, and see our post on where to buy bathroom sconces for how to shop them.
What CRI should bathroom vanity bulbs have?
90 or higher. CRI 80 bulbs are fine for hallways and closets, but at the mirror the difference in skin tone accuracy is easy to see.
Can I install a vanity light myself?
If you are comfortable with basic electrical work: breaker off, verify dead with a voltage tester, connect ground, neutral, and hot, and mount per the instructions. If any of that sounds new, have an electrician do it. It is a short, inexpensive visit.
