Bathroom Lighting Zones & Regulations Guide

When it comes to choosing lights for your bathroom, there are strict regulations in place regarding the type of lights you can use. Do not worry, as this guide will help you select the correct fittings for your bathroom.

A bathroom is split into three zones: 0, 1 and 2. This can be seen in the diagram below

Bathroom Zones

Zone 0

This zone covers inside the bath or the shower. Light fittings used in this zone must be low voltage and be rated at least IP67 which is immersion proof. Here are a few examples of the IP67 fittings we sell.

There are no special IP requirements in this zone. Except that all mains voltage fittings used in a bathroom must be connected to a circuit protected by 30m A Residual current device (RCD).

IP Ratings

IP ratings stand for “Ingress Protection” and followed by two characters. The numbers refer to the level of protection, and it is very important that you choose fittings with the correct rating according to the zone that the fittings will be installed within the bathroom.

The first digit tells you the level of protection against access to hazardous parts and the ingress of foreign objects, such as dust. The second digit tells you the protection against moisture i.e. water.

First Digit (Ingress of Solid Objects)

  • 0 – No Protection
  • 1 – Protected against penetration by solid objects 50mm+
  • 2 – Protected against penetration by solid objects 12mm+
  • 3 – Protected against penetration by solid objects 2.5mm+
  • 4 – Protected against penetration by solid objects 1mm+
  • 5 – Dust Protected
  • 6 – Dust Tight

 

Second Digit (Ingress of Water)

  • 0 – No Protection
  • 1 – Protected from vertically falling drops
  • 2 – Protected from water drops falling at a max angle of 15°
  • 3 – Protected from water as in the rain at a max angle of 60°
