• Final advice: layout first, then brightness, then style

The bathroom mirror is where lighting gets personal. It is where you shave, apply makeup, check your skin, and take a last look before leaving the house. Poor vanity lighting makes all of that harder, casting shadows that hide detail or shifting colors so your makeup looks different outdoors.

The good news is that the rules are simple once you know them. This guide covers where to mount fixtures, how bright they should be, which color temperature and color rendering to look for, and the safety basics every bathroom project needs.

Quick Answer: Light Your Face From Both Sides

The most flattering and practical vanity lighting comes from both sides of the mirror at face height. Mount a sconce on each side with the fixture centers about 60 to 66 inches above the floor and roughly 28 to 40 inches apart. If side mounting is not possible, use a bar light above the mirror, usually 75 to 80 inches from the floor and about three quarters of the mirror's width or a little wider.

For brightness, around 1,600 lumens at a single sink is a common starting point, with more for a double vanity or dark finishes. Choose a color temperature between 2700K and 3500K for most bathrooms, look for a color rendering index (CRI) of 90 or higher, and use fixtures rated for damp locations.

Why Placement Matters More Than Wattage

Most bathrooms were built with one fixture above the mirror, sometimes with a single recessed light in the ceiling. Light from above falls on the forehead, the brow, and the nose, and it leaves shadows in the eye sockets and under the chin. Turning up the brightness does not fix that. It just makes the shadows darker by comparison.

Light from the sides works differently. Two sources at face height fill in the areas an overhead light misses, which is why makeup mirrors and theater dressing rooms have used side lighting for so long. The result is even, soft light across the whole face, which makes shaving, skin care, contact lenses, and makeup easier and more accurate.

That does not mean an overhead bar light is wrong. In many bathrooms the mirror runs wall to wall or a medicine cabinet leaves no room at the sides. A well chosen bar light, mounted at the right height and paired with good ceiling light, can still do a solid job. The key is to understand the tradeoffs and choose the layout that fits your space.

The Three Main Layouts

Over the mirror bar lights

A bar or multi light fixture above the mirror is the most common layout. Mount it so the fixture sits about 75 to 80 inches above the floor, or a few inches above the top of the mirror frame. A fixture that spans at least about three quarters of the mirror's width spreads light more evenly. Shades that face up or diffuse light in all directions help reduce the harsh downward shadows that small, downward cones create.

Side sconces

A pair of sconces flanking the mirror gives the best face lighting. Center each fixture at about 60 to 66 inches from the floor, close to eye level for most adults, and space them roughly 28 to 40 inches apart. On a narrow mirror, mount the sconces directly on the wall a few inches outside the frame. On a wide mirror, the sconces can mount on the mirror itself if the product and the mirror are designed for it, or you can use a taller mirror between two sconces.

Both together

In a larger bathroom or at a double vanity, the best results often come from combining the two: side sconces for the face and a ceiling or bar fixture for general light. At a double vanity, a sconce on each side of each mirror is ideal. If space is tight, three sconces work well, with one shared fixture in the middle between the two mirrors.

Sizing and Height Chart

These are widely used starting points. Adjust for your height, your ceiling, and the fixture you choose.

If family members differ a lot in height, lean toward the middle of the side sconce range. A fixture that sits a little high for one person is better than one that shines directly into the eyes of another.

Brightness, Color Temperature, and CRI

How bright should vanity lights be?

A common guideline for a single sink is about 1,600 lumens at the mirror, split between the fixtures. A pair of side sconces might each provide around 800 lumens, or a three light bar might use three bulbs of 500 to 550 lumens each. Dark tile, dark cabinetry, and large rooms need more. White surfaces reflect light and need less. If you are unsure, go slightly brighter and add a dimmer, so the same lights work for a quick shave in the morning and a calm bath at night.

Warm, neutral, or cool?

Color temperature is measured in Kelvin. Lower numbers look warmer and more golden, higher numbers look whiter and cooler. For bathrooms, most people are comfortable between 2700K and 3500K. 2700K to 3000K feels relaxed and matches the warm light in other rooms. 3000K to 3500K looks a little crisper, which some people prefer for grooming. Very cool light around 5000K can make skin look flat and a bathroom feel clinical, so it is usually best avoided in homes.

Why CRI matters for skin tones

The color rendering index describes how accurately a light source shows colors compared with a reference source. For makeup, skin care, and choosing clothes, look for a CRI of 90 or higher. A lower CRI can make skin look dull or slightly green, which leads to foundation that looks different once you step outside.

Shades, Bulbs, and Glare

Vanity lights sit close to your face, so glare is a bigger issue here than almost anywhere else in the house. Frosted, opal, or textured glass diffuses light and softens it. Clear glass and exposed bulbs look striking but are harder on the eyes at close range, especially at eye level. If you love the look of a bare filament bulb, choose a lower output bulb, use it overhead rather than at the sides, and put the circuit on a dimmer.

Pay attention to shade direction as well. Shades that point up bounce light off the wall and ceiling and feel softer. Shades that point down send more light to the counter and sink, which can be useful but brings back some of the shadows you are trying to avoid. Linear LED bars with a diffuser are a good compromise, because they spread light across a long, even strip.

Safety and Electrical Code Basics

Bathrooms combine water, steam, and electricity, so safety comes first.

• Use fixtures rated for damp locations in bathrooms. Fixtures in a shower or directly exposed to spray need a wet location rating.
• Respect the zone around tubs and showers. Electrical code restricts hanging fixtures and certain other fixtures within a set distance of a tub rim or shower threshold. Check your local code before placing any fixture near the tub.
• Turn off the breaker before working on a fixture, and confirm the power is off with a non contact voltage tester.
• Bring in a licensed electrician to add new boxes for side sconces, move a box, add a dimmer circuit, or whenever you are unsure. Converting a single over the mirror box into two side boxes is a common request and a straightforward job for a pro.

Replacing an existing fixture with a similar one in the same box is often manageable for a confident homeowner, but local rules vary, and some areas require permits for any bathroom electrical work.

Common Mistakes to Avoid

• Relying only on recessed ceiling lights. Downlights over the vanity cast deep shadows on the face.
• Mounting side sconces too high. The benefit of side lighting disappears when the fixtures sit well above eye level.
• Choosing a bar that is too short. A small fixture over a wide mirror leaves the edges dim and the center hot.
• Mixing color temperatures. A 2700K vanity light beside a 5000K ceiling light makes both look wrong.
• Ignoring CRI. Low CRI light can make makeup and skin tones look off.
• Skipping the dimmer. Bright light is useful in the morning but harsh late at night.
• Using fixtures not rated for bathrooms. Damp rated fixtures are built to handle humidity.

Vanity Lighting Checklist

1. Measure the mirror width and height and the wall space on each side.
2. Decide between side sconces, an over the mirror fixture, or both.
3. Mark target heights: about 60 to 66 inches for sconce centers, 75 to 80 inches for a bar.
4. Plan for about 1,600 lumens at a single sink, more for dark finishes.
5. Choose one color temperature for the room, usually 2700K to 3500K.
6. Look for CRI 90 or higher if accurate color matters to you.
7. Confirm every fixture is rated for damp locations.
8. Plan a dimmer, and hire a licensed electrician for any new boxes or wiring.

Choosing a Style That Fits

Once the layout and light quality are settled, style is the fun part. Slim LED bars suit modern and minimal bathrooms. Glass shades on brass arms suit traditional, vintage, and cottage rooms. Stone, wood, and textured finishes bring warmth to spa style spaces. Match the fixture finish to the faucet or cabinet hardware, or pick a deliberate contrast such as black against warm wood.

You can browse our vanity lights for fixtures designed to sit above or beside a mirror, and our mirror lights for slim bars that mount close to the glass. If you mainly need close up light for makeup, a lighted mirror from our vanity and makeup mirrors collection can work alongside your main fixture.

Final Advice

Good vanity lighting comes down to three decisions, in this order. First, get light to both sides of the face if you can, or choose a wide, diffused fixture above the mirror if you cannot. Second, provide enough light, around 1,600 lumens for a single sink, at a comfortable color temperature with high color accuracy. Third, pick a style you will enjoy seeing every day.

Keep safety in view throughout. Use damp rated fixtures, respect the code zones around tubs and showers, and call a licensed electrician for new boxes or circuits. A bathroom that is lit well from the start is easier to use, more flattering, and more relaxing at the end of the day.
