Bathroom Lighting

Ambient bathroom lighting

Even illumination without shadows

A bathroom requires lighting that is both bright and evenly distributed, with as few shadows as possible. In smaller bathrooms, the mirror lighting may be sufficient to illuminate the entire space. Larger bathrooms, however, benefit from additional ambient lighting provided by a ceiling fixture or recessed spotlights.

Wall lights on both sides of the mirror

Mirror lighting

The golden rule is simple: the light should illuminate the face evenly — not the mirror itself. For smaller mirrors, wall lights positioned on both sides at face level provide the most flattering and practical illumination, while an additional light above the mirror completes the lighting scheme.

Choose LED light sources with a warm or neutral colour temperature (2700-4000 K) and a high Colour Rendering Index (CRI), ensuring accurate colour reproduction for makeup application, shaving, and daily grooming. Fixtures with frosted glass diffusers create a soft, comfortable, and evenly distributed light.

Lights around the mirror, dressing-room style

The "dressing room" effect

Lighting arranged around the mirror, inspired by classic theatre dressing rooms, remains one of the most flattering solutions, providing beautifully even facial illumination. A contemporary alternative is a mirror with an integrated LED light strip, offering the same effect with a clean, minimalist appearance.

Damp-rated ceiling light above the shower

Shower and bath area

The shower enclosure and surrounding wet areas should be illuminated with luminaires specifically designed for humid environments and rated with the appropriate level of ingress protection. A minimum rating of IP44 is recommended for general bathroom use, while fixtures installed directly above a shower should be rated IP65. The same specification is recommended for sauna lighting.
