There are zones in your bathroom which reflect the increased danger to you from electrical appliances and electricity. We all know that water and electricity do not mix and make a potentially lethal combination.

Electricity in any environment can be dangerous but bathrooms especially due to the presence of water, hence the need for electrical safe zones. As such only trained and qualified electricians should work with electricity in bathrooms.

It is important to understand the safety zones so that you will know what types of electrical devices can and cannot be used when you are installing them in your bathroom.

Here is an illustration of the zones as you would typically find them in your bathroom.


Zones & IP Ratings

IP ratings stand for Ingress Protection – (Essentially the level of protection an electrical item has against water). The higher the number the better. For example, an appliance or fitting with a rating of IPX1 would not be suitable for use in a bathroom. See the full list of possible ratings below.


What does this mean for your bathroom?

Zone 0 – This is essentially anywhere inside a bath, basin, or shower. It is defined as any area within a bathroom that can hold water. Any fitting or appliance used within zone 0 must be fully protected against water. (Minimum rating of IPX7).

Zones 1 and 2 – These zones in simple terms, are often labelled as the ‘splash zone,’ where installed equipment is likely to get wet but would not necessarily be submerged. Any fitting or appliance within zone 1 or 2 must be IPX4 (splash proof)

Hopefully this gives you a brief understanding of electrical zones. If you would like to find out more don’t hesitate to get in touch!
