IP (Ingress Protection) rating and Bathroom Zoning
WHAT IS IP RATING?
The resistance offered by the fixture to the penetration of solids and liquids is indicated by the IP (Ingress Protection) rating. This is a two digit number, the first number identifies the degree of protection against the ingress of solids and the second number against liquids e.g. IP65 indicates total protection against dust and protection against low pressure jets of water.

Zone 0 is the area inside the bath or shower basin (the container).
Zone 1 is limited by a) the vertical plane circumscribing the outer edge or 0,20m from the inner edge (where the ledge is too wide) of the bathtub, shower basin, or for a shower without a basin, by the vertical plane 0,60m from the shower rose, and b) the horizontal plane 2,5m above the bathtub or shower floor.
Zone 2 is limited by a) the volume external to zone 1 and the parallel vertical plane 0,60m external to Zone 1, and b) the floor and the horizontal plane 2,25m above the floor.
Zone 3 is limited by a) the vertical plane external to zone 2 and the parallel vertical plane 2,40m external to Zone 2, and b) the floor and the horizontal plane 2,25m above the floor.
