How to Choose Bathroom Lighting (Layers, Not Just a Light)

The most flattering mirror lighting comes from both sides at roughly face height, or from a fitting that distributes light evenly around the face, because this fills in the shadows that a single overhead light creates under the eyes, nose, and chin. If side lighting isn't possible, a wide, diffused fitting above the mirror is better than a small downlight. This is the layer most worth getting right if you shave, do makeup, or handle contact lenses.

It depends on the mood and tasks you want. Warmer light (around 2700–3000K) feels cosy and relaxing, while cooler, neutral light (around 3500–4000K) is crisper and better for grooming. A common, happy compromise is a warm general tone with brighter, more neutral light at the mirror, or dimmable fittings that let you shift between them. There's no single correct temperature — choose for how the room should feel and what you do in it.

Yes. Bathrooms have safety zones around the bath and shower that determine how close fittings can be to water and what rating they need. Light fittings in these wet areas must be suitably rated, and placement should be confirmed by a qualified electrician rather than guessed at. This is the one area of bathroom lighting where aesthetics genuinely take a back seat to safety, so plan it with a professional.

For many people, yes — a dimmer is one of the most rewarding additions for the cost. It lets you have bright, even light for getting ready and a soft, warm glow for a bath or a late-night trip, which makes the same room feel useful and calming at different times of day. If you're choosing one improvement to your lighting plan, a dimmable circuit often gives the most everyday pleasure for the least money.
