Current wiring regulations have identified certain zones within the bathroom to indicate which type of electrical equipment can be fitted. Lighting deemed suitable to go in these zones is given an Ingress Protection (IP) number. The first number shows the level of mechanical protection and the second shows the level of moisture protection. In both cases, the higher the number the better the protection. If a piece of equipment does not have an IP number it must not be used in zones 0, 1 or 2.
||Required IP Rating
||Inside the bath tub or shower tray (e.g. underwater lighting)
||At least IP67 and any lighting in this area must be low voltage (12v maximum)
||Directly over the bath tub or shower tray to a height of 2.25m
||At least IP65 and if the fitting is 240v a 30ma RCD must be used to protect the circuit
||Over the bath tub or shower tray above zone 1 and the area stretching 60cm outside the perimiter of the bath, shower tray or wash basin and any area within a 60cm radius of any tap
||At least IP44
||Any area outside zone 2 where no water jet is likely to be used.
