How to Choose Bathroom Lighting (Layers, Not Just a Light)
Lighting is the difference between a bathroom that looks great in photos and one that's actually nice to get ready in. It's also the detail people most often skimp on — a single ceiling light in the centre of the room, which throws shadows down onto your face exactly where you don't want them. The fix isn't more expensive fittings. It's thinking in layers.
Good bathroom lighting usually combines a few sources: light for the mirror (so you can see your face evenly), general light for the room, and sometimes a softer layer for atmosphere or late-night trips. You don't need all of these in every bathroom, but understanding the roles helps you avoid the most common regret — harsh, unflattering light at the mirror.
There are also a couple of genuine safety basics in a wet room. Let's cover the thinking first, then the practical must-knows.
Questions worth asking yourself
There’s no single correct answer here. These are the things actually worth weighing for your room and the way you live.
How is the mirror lit — from above, or from the sides?
For an even, flattering result, light at the mirror ideally comes from both sides at roughly face height, or from a fitting that wraps the light around the face. A single downlight above the mirror casts shadows under the eyes, nose, and chin. If you do anything precise at the mirror — shaving, makeup, contact lenses — this is the layer worth getting right.
What colour temperature do you actually want?
Warmer light (around 2700–3000K) feels cosy and relaxing; cooler, brighter light (3500–4000K) is crisper and better for grooming tasks. Many people like a warm, calm tone overall with brighter, neutral light at the mirror — or dimmable fittings that do both. There's no objectively right temperature; it's about the mood and the task.
Would a dimmer change how you use the room?
A dimmer is one of the most quietly transformative additions to a bathroom. Bright for getting ready, low and warm for a bath or a late-night visit. If you add just one thing to your lighting plan, a dimmable circuit often gives the most everyday pleasure for the least money.
Have you accounted for the safety zones?
Bathrooms have wiring rules about how close fittings can be to water, defined by zones around the bath and shower. This isn't something to guess at — fittings near water need the right rating, and an electrician should confirm placement. It's the one part of bathroom lighting where "looks fine" isn't good enough.
The honest bottom line
You don't need an expensive lighting scheme to get a bathroom you love getting ready in — you need the right light at the mirror, a sensible general light, and ideally a dimmer. Layering beats wattage, and a thoughtful plan with modest fittings will serve you far better than one dramatic fixture in the wrong place. Get the mirror light right, keep the safety zones in mind, and the rest is comfort.

What is the best lighting for a bathroom mirror?
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.
What colour temperature should bathroom lighting be?
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.
Do I need special lighting near a bath or shower?
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.
Is a dimmer worth it in a bathroom?
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.
