A helpful guide to both inform and to keep you safe when dealing with lighting in wet areas.

It is important to understand the IP rating by which bathroom and outdoor lights are classified to ensure that the correct product for the desired lighting application is safely installed.

The IP rating stands for 'Ingress Protection' and is always followed by two characters.
These two numbers refer to level of protection and it is important that you choose a light fittings with the correct IP rating according to where they are to be sited: outdoors or within the bathroom.

Example: IP44 - Protected against solid objects greater than 1mm, and splashing water.

First Number Short Description
(Protection against solids)
Second Number Short Description
(Protection against water)
 0 Not protected  0 Not protected
 1 Protected against solid objects > 50mm  1 Protected against falling water
 2 Protected against solid objects > 12mm  2 Protected against falling water up to 15° angle
 3 Protected against solid objects > 2.5mm  3 Protected against spraying water
 4  Protected against solid objects > 1.0mm  4 Protected against splashing water
 5 Dust - Protected  5 Protected against low pressure water jets
 6 Dust - Tight  6 Protected against high pressure water jets
     7 Protected against temporary immersion
     8 Protected against immersion

This page provides guidance for selection of fittings for use in bathrooms
and other wet areas both indoor and outdoors.

If you are not sure as to the suitability of any particular fitting please feel free to contact us 

Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12v) and be rated at least IP67 which is total immersion proof.

Zone 1 is the area above the bath to a height of 2.25m from the floor. In this zone a minimum rating of IP44 is required. If the fitting is 240v a 30ma residual current device (RCD) must also be used to protect the circuit in this zone.

Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone an IP rating of at least IP44 is required. In addition it is good practice to consider the area around a wash basin, within a 60cm radius of any tap to be considered as zone 2.

Zone 3 is anywhere outside zones 0,1 and 2 (subject to specific limits) and where no water jet is likely to be used. No IP rating is required. In addition to the above, if there is a likelihood of water jets being used for cleaning purpose in zones 1,2 and 3 a fitting rated a minimum IP65 must be used. Full details can be found in the latest copy of the IEE wiring regulations.
