Creating a Spa Sanctuary: The Rules of Bathroom Illumination

Introduction

A luxurious bathroom is not defined by marble alone. It is shaped by how light touches the mirror, the vanity, the shower, and the bath. Poor lighting can make even the most expensive finishes feel cold or impractical.

Understand Bathroom Lighting Zones

Bathrooms require careful attention to water exposure. The closer a fitting is to water, the more important the IP rating becomes.

General IP Guidance

• IP44: suitable for many bathroom areas where splashes may occur.

• IP65: recommended for shower zones or areas exposed to direct water jets.

• IP20: only suitable for dry zones away from splash exposure.

Vanity Lighting: Avoid Shadows on the Face

The vanity is the most technically important area in the bathroom. A single downlight directly above the basin often casts shadows under the eyes, nose, and chin.

Best Practice

Use vertical light at face level through wall lights on both sides of the mirror, backlit mirrors with strong forward illumination, linear mirror lighting, or a combination of side lighting and soft overhead light.

Ideal Mounting Heights

• Mount side lights approximately 150cm to 170cm from finished floor level.

• Position lights around 70cm to 90cm apart, depending on mirror width.

• Keep light sources close to face height for even illumination.

Shower Lighting

Shower lighting should be practical, safe, and visually quiet. Use recessed downlights rated appropriately for wet zones, soft beam angles, and warm colour temperature. For shower areas, IP65 is generally preferred where direct water exposure may occur.

Bath Lighting

A freestanding bath benefits from soft, indirect lighting rather than a harsh downlight directly overhead. Consider wall washing, low-level accent lighting, or a correctly specified pendant outside restricted zones.

Colour Temperature for a Spa Atmosphere

For most luxury bathrooms, REO recommends 2700K for warm spa-like softness and 3000K for refined contemporary bathrooms. For vanity areas, use CRI 90+ so skin tone and material finishes appear accurate.

Conclusion

Bathroom lighting should be calm, flattering, and correctly specified for wet environments. Browse REO bathroom lighting or contact the REO technical team for specification assistance.
