Bathroom lighting zones are designed to provide the correct level of illumination to different areas of the bathroom, while also meeting safety and health regulations. In this article, we will provide a detailed explanation of the different lighting zones for bathrooms and the requirements for each.

Zone 0

Zone 0 is the area directly above the bathtub or shower. This zone must be illuminated with a light fitting that is at least IP65 rated and is suitable for use in wet conditions. The light should be installed at least 2.25 meters above the floor, as anything lower is considered a potential hazard. The light fitting should also be of sufficient wattage to provide adequate lighting in order to allow the user to safely use the bathtub or shower.

Zone 1 is the area directly outside of the bathtub or shower. This zone is typically illuminated by wall-mounted lighting fixtures, such as sconces or wall lamps. These fixtures should be IP44 rated and should be installed at least 0.6 meters from the edge of the bathtub or shower in order to provide adequate lighting without creating any glare.

Zone 2

Zone 2 is the area around the sink, toilet, and any other bathroom fixtures. This zone should be illuminated with a light fitting that is at least IP44 rated and is suitable for wet conditions. The light fitting should be installed at least 0.6 meters from the edge of the fixture, and should be of sufficient wattage to provide adequate lighting without causing any glare.

Zone 3
