What lights can I put in a bathroom?

Bathroom Lighting Regulations

This depends on where in the bathroom the light is going and how far it will be from the water around the bath, sink and shower.
IP Ratings (Ingress Protection Ratings) are specified on each light fitting. All installations must comply with guidelines that are based on a zonal concept. Each zone rating (IP) is determined by the degree of risk of electric shock.

ZONE 0: This is the area inside the bath or shower basin and is rated at IPx7.

ZONE 1: Refers to the area above the bath or shower up to a height of 2.25 metres and carries a minimum rating of IPx4.

ZONE 2: Covers an area 0.6 metres wide immediately next to, and all around zone 1, plus the area over 2.5 metres high directly above the bath or shower. Wash basins should also be treated as zone 2. The minimum rating here is IP x 4. Where water jets are likely to be used for cleaning purposes in zones 1 and 2, the rating is a minimum IPx5.

OUTSIDE ZONE: Covers any area outside Zone 1 and Zone 2, there is no special requirement in this zone. Bathrooms are now allowed to contain a socket outlet, this must be located 3M outside Zone 1. Lighting circuits and any socket outlet circuit in a room containing a bath and/or shower must be provided with 30MA RCD protection.

AREAS AROUND SINKS: Covers up to 60cm. Zone 2 IPx4 luminaires should be installed in this zone.
