What are bathroom zones and IP ratings? How do you know what IP rating YOU need? We explain how to fit bathroom electrics safely and with legal compliance. Here is a step-by-step guide to help you understand how to install lighting fixtures in zones 1 and 2: Identify the different zones in your bathroom according to the layout and proximity to water sources. Select lighting fixtures that are specifically designed for use in bathroom zones 1 and 2.
Zone 2 Bathroom Lights can be used in an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25 from the floor. In this zone IP rating of at least IP44 is required. Zone 2 - This is the area stretching to 0.6m outside of the bath or shower.
IP rating must protect against water spray from all directions (IPX4/IP44). Outside Zones - (Previously Zone 3, which was removed under the 17th Edition Wiring Regulations BS7671) No IP Rating required. (See diagram for bathroom zonal areas).
Bathrooms are divided into two distinct zones based on their proximity to water sources and the potential for electrical hazards. These zones, known as Zone 1 and Zone 2, play a crucial role in ensuring the safety and functionality of bathroom spaces. The bathroom zones are as follows: Zone 0: The area inside the bath or shower - this would also apply to shower enclosures and wet rooms too.
Zone 1: The area above the bath or shower up to a height of 2.25 from floor level. Zone 2: The area reaching 0.6m outside the bath's perimeter, up to a height of 2.25m from the floor. For zone 0, light fittings need to be at least a minimum of IP67 which means immersion proof.
Lights used in zone 0 will also need to be low voltage, with a maximum of 12V. Zone 1 This is the area of the bathroom that is directly above the bath tub and the shower, up to a height of 2.25m from the bathroom floor and at a 1.2m radius from water.
