When planning a lighting scheme for your bathroom it is important to ensure that the fittings you are looking to purchase can be installed in their desired location. All light fittings have what is known as an IP Rating, it is this rating that determines where a light can be installed. More information on IP Ratings can be found in our IP Ratings Explained page, please click here to visit.
Once you have ascertained the IP Rating of the fitting, please use the guide below and the map opposite to see if it can be installed where you would like.
You should always seek advice from a qualified electrician before installing lighting within a Bathroom. N.B Regulations apply to domestic applications only, according to IEE Wiring Regulations (17th Edition) BS 7671:2008 For non domestic applications, please refer to your electrician
