Here are a selection of ceiling and wall lights suitable for the Outside Zones in your bathroom, the area in your bathroom or en-suite that is basically anything that is not within zones 0-2. It is always encouraged that any lights used should have a rating of at least IP44.
The space and size of zones can be limited by walls and ceilings, among other things. For more information, we recommend looking at BS 7671 with their detailed diagrams and check with your electrician. It is always recommended to consult a professional and qualified individual to carry out electrical work in bathrooms.
