How to Fit An Electric Shower (And Why It’s Worth It)

How to Fit An Electric Shower

Electric showers have a lot of perks and the installation process is easier than your usual shower. We explain everything you need to know!

Electric showers are popular because they are easy to install. Most models can be directly connected to the home’s mains water supply.

Installing an appliance for the first time can be daunting. No worries. We cover the reasons why an electric shower is worth it and how you can successfully install it in your bathroom.

How To Fit An Electric Shower For The First Time

The good news is that an electric shower is definitely easier to install than a traditional shower. It does not need to be connected to the boiler or any other hot water point. You link it to the mains water supply and turn it on. How does it heat water? These showers contain an electric element that rapidly heats flowing water.

What Are The Benefits Of An Electrical Shower?

  • The appliance saves power.
  • The installation is easy.
  • Family members can all enjoy hot showers the same evening or morning (traditional systems tend to run cold).
  • Electric showers suit most plumbing systems.

How Do I Install An Electric Shower?

The place to start is to check that your chosen model is compatible with your home’s plumbing system and if you are satisfied with the kilowatt rating. You also need a drill (and maybe a gift for the neighbours if they hate noise).

How To Prepare For The Installation

Ready? Preparation involves a 3-step process.

  1. First, prepare the pipework. This involves running a 15 mm pipe from the cold water reservoir to the wall where you intend to fit the shower. This is called the inlet pipe.
  2. Now fit a valve into the pipe and then insert the connector for the unit.
  3. Lastly, you need to install the electricity supply. Start by drilling a hole in the wall for the electric wires. Now run these electric cables from the shower to a double-pole pull-cord switch mounted on the ceiling.

How To Install The Electric Shower

Always make sure that you read the instructions that come with the model you purchased. These guidelines are the closest to a correct procedure that you can hope for. But in case you haven’t yet bought the shower and want to get an idea of what the procedure entails, the most common steps can be found below.

  1. The first step in the installation procedure is to drill holes in the walls where the shower unit will be fitted. Use a masonry bit to drill these holes but if you are drilling on a tiled surface, it is advisable to use a tile bit.
  2. Insert the wall plugs and squeeze a small amount of sanitary silicone sealant into each of these holes.
  3. Feed the pipe and electrical wires through the backplate of the shower unit and then screw it into position using the screws that came with the package.
  4. Now join the inlet pipe with the shower unit and use a pipe wrench to tighten the compression fitting.
  5. Once you have correctly connected the pipe to the shower unit, fix the electrical cable to the unit. Do this by connecting the neutral cores to the terminals marked “load” and the earth to the earth terminal.
  6. Fit the cover and the rail. Ensure that you adhere to the manufacturers’ instructions to avoid misaligning the rubber seal on the cover. Also, make sure that when you are fitting the rail, the showerhead should not dangle less than 25 mm from the spill-over level of your shower tray, bath, washbasin or bidet. This will prevent dirty water from finding its way back into the clean water supply.
  7. Follow the instruction manual to screw one end of the hose to the handset.
  8. Before you screw the other end to the shower unit, countercheck everything to make sure that it is working correctly.
  9. If everything is working, screw the other end of the hose to the shower unit and enjoy your hot shower!
