If you have an electric shower in your home, there may come a time when you will need to replace it in order to upgrade your shower or due to a malfunction. Although still far from common, electric showers are steadily gaining popularity due to their energy saving properties and their reliability in terms of providing a steady flow of hot water. Below you will find a basic guide to replacing an electric shower in your home.

Step 1 - Turn Off Utilities

Since this is a project that requires you to work around electrical wiring, the first safety precaution that must be taken will be to turn off the power in the project area. Making this project even more dangerous is the fact that you will be working not only around electricity, but also water. Since the combination of water and electricity has the potential to be fatal, just be sure that all electricity is turned off before continuing. If you are unsure of proper procedures for working around electrical wiring, or if you would rather not deal with this portion of the project, don’t hesitate to contact an electrician. In addition to turning off the electricity, you will also want to turn off the water in order to avoid a mess.

Step 2 - Remove Old Shower

Typically, you should be able to remove your current shower housing using a screwdriver and wrench set.

Step 3 - Test Electricity

To do this, use a continuity tester to check the polarity of the wires. For the purposes of this tutorial, we will assume that the electrical wiring feeding into the shower itself is in proper, working condition. If this is not the case, and if a problem in the electrical system of your house is suspected, you will need to diagnose the problem in a separate project, or, more likely, hire a professional electrician to assess the current state of your electrical wiring in the area surrounding the shower.

Step 4 - Install New Shower

Carefully read and examine the manufacturer's instructions for installing your new electric shower. In general, however, installation will consist of connecting the electrical cabling that you have already exposed and tested in previous steps to the electrical box found in the housing of your new unit.

Follow the instructions carefully to ensure that the wiring is completely safely and properly. If there is an earth-bonding cable present in your system, check to see if you have an earth-bonded pipe designed for this purpose. It not, connect this cable to the water main and any other pipes in the room. After attaching the electrical components of the shower, attach the water main to the shower. Mount the shower on the wall of your shower stall using the manufacturer's recommended procedure.

Step 5 - Test New Shower

Turn on the electricity and water to the area and test to make sure your new shower system is working properly.
