The right vanity light does two jobs at once: it makes your bathroom look finished, and it makes you look your best in the mirror. Get it wrong and you're stuck with harsh shadows and an unflattering glare every morning. This guide walks through how to choose a bath bar — the horizontal fixture that mounts above or beside the mirror — so you land on something that's both practical and stylish.
Why bath bar placement matters
Bathroom lighting is about eliminating shadows on the face. A single ceiling fixture casts light down from above, which drops shadows under the eyes, nose, and chin — not ideal for grooming or makeup. A bath bar mounted above the mirror, ideally paired with fixtures or sconces on either side, wraps light around the face far more evenly. If you only have room for one fixture, above the mirror is the priority spot.
How to size a vanity light
A good rule of thumb: an over-mirror bath bar should be about 75% of the width of your mirror or vanity, so it feels proportional rather than stubby or overpowering. Mount it roughly 75 to 80 inches from the floor, centered over the sink. For double vanities, either choose one long bar centered over the whole unit or place a fixture above each mirror. When in doubt, measure your mirror first and shop to that number.
Choosing a finish and style
Your vanity light is a chance to set the tone of the whole bathroom. Warm metals like brass and gold feel elegant and current; matte black reads modern and graphic; and chrome or nickel stays classic and clean. Coordinate the finish with your faucet and cabinet hardware for a pulled-together look — they don't have to match exactly, but they should share a warm or cool family.
Shade style matters too. Fixtures with the bulbs pointing up cast softer, more ambient light; those pointing down are more task-focused. Frosted or textured glass shades diffuse the glow and cut glare, which is usually the most flattering choice at the mirror.

Don't forget bulb color
For bathrooms, aim for a bulb color temperature between 2700K and 3000K — warm enough to feel inviting but bright enough to see clearly. Avoid very cool, bluish light at the vanity, which can look clinical and wash out skin tones. A high color-rendering bulb helps colors (and your makeup) look true.
