IP stands for 'Ingress Protection'.

First Digit - Protection against ingress of foreign bodies e.g. tools, dust, fingers, etc.

Second Digit - Protection against ingress of liquids. e.g. IP44 is protection against solid objects greater than 1mm IP4X and waters sprayed from all directions IPX4.

IP Ratings In Bathrooms

The bathroom area has been divided up into 'zones' or areas which are classified using the numbers 0-2.    Light fittings are then assigned an IP rating which indicates how much protection they provide against ingress of water and other particles. Each zone has a minimum IP requirement that must be met if a fitting is to be installed in this area.

Bathroom Zones

 

ZONE
0

Inside the bath or shower. Any fittings used here must be SELV (max 12v) and have a minimum rating of IPX7 (protected against immersion in water)

ZONE
1

Above the bath or shower to a height of 2.25m. A minimum rating of IPX4 is required. If there is a likelyhood of water jets being used for cleaning the IPrating should be increased to IPX5.

ZONE
2

The area stretching to 0.6m outside the bath or shower and above the bath or shower if over 2.25m. An IP rating of at least IPX4 is required. If there is a likelyhood of water jets being used for cleaning the IPrating should be increased to IPX5.
