The bathroom is bright enough to find a dropped contact lens. Somehow, shaving still happens in a small cave under your eyebrows. More ceiling light may not solve that particular problem.
Put light where the task happens
Kichler's bathroom-lighting guidance favours useful face lighting and explains the limitations of overhead shadows. Mock up the proposed locations with the mirror size and actual users in mind. Decorative symmetry should not be the only placement test.
Check the quiet evening setting too
Compare glare, diffusion, colour appearance, and dimming as a combination. A backlit mirror can make a pleasing halo without necessarily providing enough forward light for grooming. Ask the electrician to confirm fixture suitability and placement requirements. Settle this before the wall finish makes moving a box an expensive little adventure.
Before the next step
- Test lighting at face height for the people using the room.
- Check full brightness and a comfortable evening setting.
- Coordinate mirror, boxes, controls, and fixture suitability before finishing.
A mirror light earns its place by helping you see yourself comfortably. That is a better audition than looking attractive while switched off.
