How to fit an electric shower
Pick a location for your electric shower that is near the main cold water supply and close to a spot where you can install an independent circuit.
Consult an electrician for advice on the size and type of independent circuit to install for your shower to ensure that you have adequate electricity.
You will likely have to include a consumer unit with your circuit.
Consult a plumber to ensure that your building's plumbing system will be able to accommodate an electric shower. Install the independent circuit near the location of the electric shower along with any necessary consumer units or earth cables.
