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.
Choose your answer from:
- Choose a cement floor so that there is only a 6-inch (15. 2-cm) gap between the floor and the surrounding foundation or cudrywall.
- Check your electricity bill to make sure that it is charged. Consider installing a dual circuit shower where the water supply is charged and the heat from the shower is turned off.
- 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.
- Be sure that if you use more than one agency, that agency will be able to evaluate the possible breakage of the unit and determine the size of the outlets/breaker box. Use a refrigerated refrigerator at room temperature.
