Bathroom Lighting Ideas: One Bathroom, Three Lighting Plans (Part One)
30 Sep 2026
Your bathroom has to wake you up in the morning and wind you down at night, and most bathrooms are lit to do neither. Light is usually an afterthought: a pancake downlight (or two) in the middle of the ceiling, a little light in the joinery, and a couple of wall lights for the "look".
"I can't see my face in the mirror" is the complaint we hear most
Almost every bathroom we walk into is lit from the centre of the room. The floor tiles look great, but at the mirror all that light is behind your head, and your head throws a shadow right where you're trying to look. Part Two covers the mirror in detail. This post follows one bathroom through three lighting designs, rendered from real light fitting performance data, to show how layering light changes the way the whole room feels and works.
Four downlights and a very well-lit floor
We've used a large bathroom to make the light easier to see, but the principles hold at any size. The standard grid of four downlights looks fine in a picture, yet the room is flat and the floor has become the hero. You can't see your face in the mirror, a 3am trip to the loo means switching on all four lights (goodbye, sleep), and a long soak happens under a ceiling full of glare. Yes, you can light a candle. When the lighting is designed for the room, the candles are there because you want them.
Every bathroom needs three layers, and one of them is barely there
Functional light at the mirror for grooming, bright and high quality.
Decorative light for the things you love, like a feature wall or a beautiful wall light. Decorative lights are jewellery (lovely, and no help at all when you're shaving).
A night light that sits down low, on its own switch, and dimmer than you think. Around 100 lumens is plenty.
Put each layer on its own switch. Motion sensors suit the night layer, unless your ensuite opens straight off the bedroom, where a switch and a closed door beats a 3am floodlight.
Plan early: Electrical rough-in is the deadline for lighting decisions, because moving a cable once the walls are waterproofed and tiled is serious money. Start your lighting plan at least a month before rough-in, which gives you time to choose your lights. If the perfect light still hasn't turned up, install a simple placeholder on the right cable and upgrade later. The cabling is the commitment.
The light, bright version, where every layer earns its place
At the mirror, a slender bar light pushes powerful, diffuse light down the face of the mirror for grooming without glare or shadow. Beside the bath, in-ground uplights wash light up the wall, enough to read a book by without sitting in the spotlight. They need to be IP67 with a remote driver, and your build team must be exceptional at waterproofing, because every one of them is a hole in a bathroom floor. Use them carefully.
A linear LED strip in the shower brings in brighter light and highlights the feature wall. It sits in Zone 1, so it needs to be IP65 with a remote driver (Part Three explains the zones). Light under the floating vanity becomes the night light, which works when the vanity is under 1m long, or when the light is on automation that brings it on at a very low output late at night. Glass pendants add sparkle, safely outside the bath zones (however much Pinterest disagrees, pendants over baths aren't compliant in Australia). A small light in the niche above the bath is decorative, with a second life as a night light.
The dramatic version, where the ceiling becomes the light fitting
This time the mirror gets serious functional light, with adjustable fittings aimed to reflect out of the mirror onto your face, for anyone who needs a lot of light for shaving or makeup. When they're off, a halo around the mirror and the night light under the vanity carry the room.
Uplights at each end bounce light off the ceiling, turning it into one big soft light and making the room feel taller and wider (that's the magic of reflected light). Light grazing down the far wall brings textured finishes to life, and the niche light stays for a styled vignette or a long soak.
Your bathroom might need none of these, and that's fine
Between the three designs we've grazed walls, bounced light off the ceiling, and tucked light under the vanity and into a niche. In the right combination, they give you a bright, comfortable room that doesn't remind you of the surgical suite at your local hospital. A small bathroom might need nothing more than great light at the mirror and a night light. A large one will need every layer.

Bathrooms are demanding little rooms, asked to wake you up, wind you down and keep you safe around water, often in very few square metres. Start at the mirror and give the light the same attention as the tapware. And don't underestimate the smallest layer, the one you'll only use at 3am. It's often the one you'll thank yourself for.
