When you are looking at lights for the bathroom, you need to consider in which bathroom lighting zones you will place your lights in order to avoid mixing electricity and water together. Below you will find the guidelines set out by the IEE Wiring Regulations.
Bathrooms are divided into three lighting/humidity zones. The closer your light is to the water source, the higher the risk of getting the light wet. This in turn means the higher IP rating fitting you will need.
|Bathroom Lighting Zones||Description of Zone IP Rating Required|
|Zone 0||Inside bath or shower itself. Fitting must be IP67 or greater.|
|Zone 1||Above the bath or shower to a height of 2.25m. Fitting must be IP44 or greater.|
|Zone 2||In an area stretching outside of the bath or shower by 0.6 metres wide and the area outside of the 2.25 metres directly above the bath or shower. This zone also covers the area directly next to Zone 1, all around Zone 1. Fitting must be a IP44 or greater.|
What do the numbers for IP rating mean?
|Protection against solid objects||Second
|Protection against fluids|
|0||No protection||0||No protection|
|1||Protection against solid objects over 50mm, e.g. accidental touch by hands||1||Protection against vertically falling drops of water|
|2||Protection against solid objects over 12mm, e.g. fingers||2||Protection against direct sprays of water up to 15 degrees from the vertical|
|3||Protection against solid objects over 2.5mm (tools/wires)||3||Protection against sprays to 60 degrees from the vertical|
|4||Protection against solid objects over 1mm (tools / wires / small wires)||4||Protection against water sprayed from all directions – limited ingress permitted|
|5||Protection against dust – limited ingress (no harmful deposit)||5||Protection against low pressure jets of water from all direction – limited ingress permitted|
|6||Totally protected against dust||6||Protection against strong jets of water, e.g. for use on ship decks – limited ingress permitted|
|7||Protection against the effects of immersion between 15cm and 1m|
|8||Protection against long periods of immersion under pressure|
