Our guide to IP Ratings & Bathroom Zones

29 Nov 2022


What is an IP Rating?

IP rating stands for 'Ingress Protection rating' and this helps determine what electrical items can be installed in certain bathroom zones.

Take a look at our diagram below to easily identify your bathroom zones. 


What Are Bathroom Zones?

Bathrooms are divided into 4 zones, these are areas where electrical equipment must offer a certain level of protection against water. The zone number refers to the amount of water likely to be present. The lower the zone number, the higher the IP rating needs to be. 

For example, Zone 0 covers areas inside baths and shower enclosures. These areas must have a minimum IP rating of IP67.

Zone 0 

Zone 0 is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12V) and be rated at least IP67 which is total immersion proof. 

We do not currently have any fittings that are suitable for Zone 0 

Zone 1 

Zone 1 is the area above the bath to a height of 2.25m from the floor. An IP65 rating is recommended. 

All lights in our Duomo Piccolo collection are rated IP65 and are suitable for installation in Zone 1. The lights in this collection are also suitable for installation outdoors.

Zone 2 

Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In these bathroom zones an IP rating of at least IP44 is required. In addition, it is good practice to consider the area around a basin, within a 60cm radius of any tap, to be considered as zone 2. 

The following lights are suitable for installation in Zone 2:
Code Zero Wall Sconce (IP44)
Petrine Wall Sconce (IP44)
Duomo Piccolo Stem Wall Light (IP65)
Duomo Piccolo Wall Sconce (IP65)
Duomo Piccolo Pendant (IP65)

Zone 3

Zone 3 is anywhere outside zones 0, 1, and 2 and where no water jet is likely to be used.
No IP rating is required here.

The following lights are suitable for installation in Zone 3:
Code Pendant Collection (IP20)
Petrine Single Pendant (IP20)
Petrine Double Pendant (IP20)
Tasman Pendant Collection (IP20)
So Sconce (IP20)
Offcut Sconce (IP20)

Always ensure any electrical work in your bathroom is carried out by a qualified electrician.
