Bathroom Lighting Regulations

The Lighting circuit within a bathroom should be protected with a 30MA residual current device (RCD)

Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage (max 12v) and be at least IP67 which is immersion proof.

Zone 1 is the area above the bath to a height of 2.25m from the floor. In this zone a minimum rating of IP44 is required.

Zone 2 is the area stretching on 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone an IP rating of at least IP44 is required.

In addition to this it is good practise to consider the area around the wash basin, within a 60 cm radius of any tap to be considered as zone 2 IP44.
