I spent three weekends tiling the bathroom walls. I hired a plumber for the new vanity. I agonized over the faucet finish for two months. And then I installed a single overhead light and called it done. Three months later I realized I couldn't apply mascara without leaning into the mirror until my nose touched it.
The problem was the overhead fixture. A single ceiling light illuminates the top of your head. It does not illuminate your face. The shadows it creates across the eye sockets and jaw are the exact opposite of what you need at a bathroom mirror. It's also the exact setup that builders default to because it's the cheapest one.
The Fix That Actually Works
A pair of bathroom sconces flanking the mirror at eye height. Mounted at 60-65 inches from the floor, they provide side light that hits the face evenly from both directions, eliminating shadows rather than creating them. The overhead fixture is still useful for ambient light, but it's the sconces that make the mirror functional.
I installed mine on a separate dimmer from the overhead. Morning routine: both on full. Evening wind-down: sconces at 30%, overhead off. The room transformed from a bathroom with a lighting problem into a bathroom that actually worked.
If ceiling height allows, a pendant light over a freestanding tub adds a layer that makes the room feel designed rather than installed. This is the move that turns a functional bathroom into one guests comment on.

Michelle at The Wharton House documented the exact opposite mistake, doing her makeup in dim light for four years before finally installing side-mounted sconces. Same problem, same fix.
Frequently Asked Questions
What is the most common bathroom lighting mistake?
Installing a single overhead fixture and nothing else. Overhead-only lighting casts harsh downward shadows on the face. The opposite of what you want for a mirror. Flanking sconces at eye level (60-65 inches from the floor) eliminate shadows and provide the even, flattering light that makes a bathroom mirror actually useful.
Where should bathroom sconces be placed?
Mount vanity sconces on either side of the mirror, centered at 60-65 inches from the floor. This positions the light at face level rather than above it. If your bathroom only has room for one fixture above the mirror, choose a horizontal bar light rather than a single centered pendant. It distributes light more evenly.
What bulb color temperature is best for a bathroom?
2700K-3000K warm white gives the most flattering and accurate light for skin tones. Cooler temperatures (4000K+) are harsher and make the bathroom feel clinical. If your bathroom doubles as a relaxation space, staying at 2700K creates the warmest, most spa-like atmosphere.
