The following information is intended as a guide. If in any doubt, seek the advice of a qualified Electrician.

Great care must be taken when choosing bathroom lighting as there are strict regulations concerning the type of light fitting that may be used. Bathrooms are split into the following zones, see the diagram shown:

Bathroom zones diagram

Zone 1 is the area above the bath to a height of 2.25m. This zone has a minimum rating of IP44. Therefore any light fitting installed in this zone must have an IP44 rating. Also if the light fitting is 240v, it must be protected by a 30ma RCD.

Zone 2 is the area stretching 0.6m outside the bath perimeter to a height of 2.25m. Again a light fitting with a minimum rating of IP44 is required. the area around the basin should also be considered as zone 2.

Zone 3 is no longer defined and is just "Outside Zones". Protection required is IP20 for normal domestic use.
