Bathroom Lighting Zones

All electrical work in a bathroom must be carried out by a qualified electrician, this guide is to help you to choose the right lights for your bathroom. Our staff at our retail outlet are also happy to help with any enquiries about any lighting issues that you would like to discuss and can offer advice if you feel you would like more information.

For the purposes of lighting a bathroom is divided into Zones. These Zones are determined by the closeness of water and humidity and the likelihood of the light fitting getting wet. Bathroom light fittings are given an IP rating, which relates to these zones.

The first digit of an IP rating describes its protection from solid objects such as gravel, insects and other dust. The second digit relates to its protection from moisture, which is directly relevant to the bathroom. The higher the number, the more protection it has.

• Only light fittings suitable for the relevant zone should be used.
• Avoid lighting, which is too bright as the polished surfaces may cause glare; diffused wall or ceiling lights are a good idea.
• The main light should be switched on by a pull cord or a light switch situated outside the bathroom.

Zone 0 - the interior of the bath or shower that can hold water. Requires electrical products to be low voltage (max 12V) and rated IPX7.

Zone 1 - the area directly above zone 0, limited to a height of 2.25m above the bath or shower. Requires electrical products to have an IPX4 or better. 

Zone 2 - the area beyond zones 0 and 1, stretching 0.6m horizontally and up to 2.25m vertically. Also includes the recessed area of a window with a sill next to the bath. Requires electrical products to have an IPX4 or better.
