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. Explanation of bathroom Lighting zones with chart and IP (Ingress Protection) ratings table. This guide outlines key considerations for bathroom lighting safety, including zoning regulations, Ingress Protection (IP) ratings, and best practices for fixture selection and installation.
Bathrooms are divided into specific zones that dictate the type of lighting fixtures permissible in each area. 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) The numbers that follow an IP rating each have a specific meaning. Zone 1: A shower area, whether an enclosed shower or a bathtub with a shower nozzle, up to a height of 2.25 metres. The minimum IP rating for an appliance in this zone is IP44, meaning it must be protected against all solid objects and any splashing liquid.
Zone 2 600mm outside a bath, shower, sink or water outlet. A rating of at least IP44 is required. You may well be familiar with the term zoning in interior design, but when it comes to bathroom zones, there's an additional all-to-important reason why they matter so much.
As well as defining the spaces where your sanitaryware is positioned, each zone relates to an IP rating for electrical items. IP44: This rating indicates that the fixture is protected against splashes of water from any direction and can be safely used in Zone 2 and outside zones. IP65: This rating indicates that the fixture is protected against low.
Ceiling lights in general bathroom areas (outside wet zones) need at least IP44 protection to handle humidity and occasional splashes. However, for lights directly above bathtubs or showers, go for IP65 or higher to withstand water jets. Learn which IP ratings your bathroom lights really need-from IP44 to IP65-and discover how to balance safety, design, and everyday luxury with Pooky.
