Almost all of us know that electricity and water do not mix well. A bathroom is usually a small space, and therefore some people are scared to place a wall heater in such a small, mostly enclosed area.

Important factors to keep in mind when adding an electric wall heater to your bathroom is the size of your bathroom. If there is a bathtub in your bathroom or not, and the IP reading of your heater. If you have a bathtub in your bathroom, knowing where to place your heater is essential.

We have all seen a movie where somebody is shocked in the bathtub when using an electric appliance. So, is it safe to have an electric heater in the bathroom close to your bathtub?

How Close Can An Electric Wall Heater Be To The Bathtub?

This is a tricky question. When placing an electric heater in your bathroom, it is essential first to inspect the appliance’s Ingress Protection (IP) rating.

Adax explains the format of the rating will be XXIP.

XX represents the numbers that will indicate if the heater is safe for wet room use. If electric heaters are placed 88.58 inches above the bathtub’s edge, their IP rating should be IPX4.

Most electric heaters have an IP24 rating. This means that they should be placed 23.6 inches away from the bathtub edges and 88.58 inches up the wall.

Are you a bit confused about this IP rating?

Don’t worry, the following will explain it perfectly.

The universal IP rating can be explained as follow:
