No IP rating is required. However, if there is a likelihood of water jets being used for cleaning purposes in zones 1, 2 and 3, a fitting rated a minimum IP65 must be used. For more information on IP ratings and bathroom zones then we would advise checking the 17th Edition Wiring Regulations by the IEE and IET.
What is an IP rating? Once you understand what and IP rating is, it's easier to appreciate why certain bathroom zones are limited to specific IP ratings. "An IP rating (Ingress Protection) is a simple guide that tells you how well a lighting fixture is protected against dust and moisture," explains Mara Rypacek Miller, founder of Industville. Zone 0 - Inside the bath or shower.
IP rating must protect against immersion/total immersion in water (IPX7/IP67). Zone 1 - Above the bath or shower to a height of 2.25m. IP rating must protect against water spray from all directions (IPX4/IP44).
Zone 2. Bathroom Zones - The IP Standard The Ingress Protection (IP) Standard is a rating system for categorising electrical appliances by their ability to keep out foreign bodies, such as dust particles and water. For bathroom electronics, this is most relevant in preventing water from entering the appliance and causing a potentially dangerous malfunction.
This system is now the standard in the UK. Explanation of bathroom Lighting zones with chart and IP (Ingress Protection) ratings table. This bathroom electrical zone refers to the area directly above Bathroom Zone 0, extending up to 2.25 metres from the floor.
In Bathroom Zone 1, electrical fixtures must be water-resistant to handle splashing and occasional moisture, with a minimum rating of IPX4 (or IPX5 when water jets are present). When choosing products for this bathroom zone, it's essential to ensure they meet the.

2.Choose Appropriate Fixtures: Select fixtures designed for bathroom use, ensuring they have the correct IP ratings for their intended zones. For instance, ceiling lights in Zone 1 should be rated at least IP44, with IP65 being preferable for added safety. Zone 1 Up to 2250mm above bath, shower or wet room basin.
A minimum rating of IP44. For 240V fittings, a 30ma RCD must also be used to protect the circuit. Understanding how IP ratings correspond to bathroom zones is key to safe lighting choices.
For example, Zone 0 requires IP67 for immersion resistance, Zone 1 needs at least IP44 (though IP65 is better for protection against water jets), and Zone 2 calls for IP44 to guard against splashes.
