Bathroom Lighting Guide

Bathroom lighting needs to be functional and planned with safety in mind, due to high moisture levels in the bathroom there are a number of rules and regulations which must be adhered to. Our lighting guide aims to remove the stress of choosing the correct lights to complete your beautiful bathroom.

Zone 2: Over the bath or shower tray but above Zone 1. Zone 2 also covers the area stretching 0.6 outside the perimeter pf the bath and to a height of 2.25m from the floor. The area around the wash basin is also Zone 2 if within a 60cm radius of any tap. Lighting in this area should be at least IP44.

Zone 0: Inside bath or shower tray. Any light fitting installed in this area must be low voltage (12v max) and have an IP rating of at least IP67. An IP44 light is not suitable for this area.

Zone 1: Directly above the bath or shower tray up to a height of 2.25m from the floor. Light fittings installed in this area should be IP44 or higher. If the fitting is 240V a 30ma RCD must be used to protect the circuit.

RCD, Volts

  • A volt is the potential electrical energy if the current is allowed to flow to a specific source. The UK electricity main supply is approx. 240 volts, and if not used properly has the potential to seriously harm. Electrical appliances, circuits, cables and plugs are designed to reduce the chance of an electric shock.
  • RCD ? A Residual Current Device, or RCD, is a safety device that automatically switches off electricity, in some circuits, if a fault is detected. They are designed to prevent electric shocks and electrical fires. This device offers a level of personal protection the ordinary circuit breakers do not provide.

IP Rating

  • Each light fitting is given an IP (Ingress Protection Marking) number rating that relates to its water resistance.

    An IP rating has two numbers and each number has a specific meaning; these numbers are an important guideline when purchasing lighting for a bathroom. The first number after the IP indicates the degree of protection of enclosed electrical equipment from foreign bodies. The second defines the protection from moisture.

    When you buy lighting that is intended for use in a bathroom you need a minimum IP44 rating, and you must ensure that the light fitting is suitable for the relevant zones that they are intended to be used in.
