Bathroom Lighting Ideas: Mirror Light, IP Ratings and Mood
Good bathroom light lets you see your face clearly at the mirror and relax in the evening. Vanity lighting without shadows, what IP ratings mean in wet areas, and ideas for small and ensuite bathrooms.
Bathrooms are small, often windowless and full of reflective surfaces, so lighting makes a big difference. The aim is clear, shadow-free light at the mirror, safe fittings near water, and a softer option for the evening.
Light the mirror from the sides or front
A single downlight above the vanity casts shadows under the eyes and chin. Better options:
- Wall lights either side of the mirror at about face height: the most flattering light.
- A light bar above the mirror that projects forward rather than straight down.
- Backlit or LED-framed mirrors that light the face evenly.
IP ratings and wet areas
An IP rating has two digits: the first is protection against dust and solids, the second against water. Wet areas have zones under the Australian wiring rules, and fittings near the shower or bath need an appropriate rating. As a general guide, IP44 or higher is common in bathrooms and higher ratings are needed closer to water. Your electrician will choose fittings and positions that comply.
General light
- Downlights with a suitable IP rating over the shower and the centre of the room.
- A ceiling fitting with an enclosed, moisture-resistant diffuser in smaller bathrooms.
- Exhaust fans with built-in lights save a ceiling position in small rooms.
Mood and accent
- LED strip under a floating vanity or in a shower niche, rated for wet areas.
- Dimmable lights for baths in the evening.
- A low night light or motion sensor strip for late-night trips without being dazzled.
Colour temperature
Neutral to warm white (3000–4000 K) with good colour rendering (CRI 90+) shows skin tones accurately for grooming and makeup. Warm white on a separate dimmed circuit creates a relaxing evening mood.
Small bathroom and ensuite ideas
- A lit mirror cabinet doubles as storage and vanity light.
- Light-coloured surfaces bounce light and make the room feel larger.
- One well-placed downlight in the shower plus mirror lighting is often enough.
Choosing globes: LED light bulbs.
In Australia, installing or replacing hard-wired lighting must be done by a licensed electrician.
