What is an Electric Shower?
An electric shower uses a water heater system that heats water on demand, without the need for a boiler. Electric showers are usually more energy-efficient than conventional showers as they only heat the water when it is used, rather than continuously heating a large volume of water. So, not only are they eco-friendly they’re more economical, too.
Electric showers come in a variety of styles, sizes, and finishes. They may have in the past been thought of as unstylish, but these days you can find a huge variety of modern electric showers.
Before You Begin
Prior to installing the electric shower, you will need a 15mm plumbing supply, electric cable (the size of the cable will depend on the kilowatt rating of the shower unit), screwdriver, pencil and drill with a masonry bit, or tile bit if there are tiles. You will also need to prepare the pipework and electric supply.
The steps required are:
- Ensure electrics and water supply are turned off at the mains.
- Run a 15mm pipe from the cold water supply at the storage tank to the wall where the shower will be placed.
- Mark where the inlet pipe and power supply cable will go by holding the shower unit in the desired position.
- With a pipe and cable detector, check there are no pipes or cables where you will drill.
- Begin to run the 15mm plumbing supply where you’ve marked. Then fit an isolating valve in the pipe and insert the connector for the shower unit.
- Drill a hole for the electric cable, and proceed to run the cable from where the unit will be placed to the ceiling-mounted cord switch, this must not be fitted in electrical zones 1 or 2.
- Only a qualified electrician should make the final connection from the shower unit’s circuit to the consumer unit. For safety reasons we would not recommend doing this yourself. Always ask a qualified electrician to check over the installation before turning your supply back on and using the shower.
How to Install an Electric Shower

Ensure electrics and water supply is switched off at the mains. If you’re replacing an electric shower, begin by removing the old unit. Use a screwdriver to unscrew the fixtures.

Attach the live and neutral cores to the load terminals, and then the earth core to the earth terminal.

Place the cover on the unit and then fit the rail.

Lastly, connect the hose to the handset, and then connect the other end of the hose to the electric shower unit.
Can an Electric Shower be Fitted to any Bathroom?
Yes, electric showers can be fitted to any bathroom and any home. The electric shower has its own water heating system, so no matter what plumbing system is in your home, an electric shower will work. You can fit an electric shower in a shower enclosure, or over a bath. There should be ample space around the shower unit to remove the cover, should you need to service or replace the unit.
Additionally, depending on where your power source is located and how accessible it is, you may need some additional help from an expert in order to install an electric shower correctly.
How Much Does it Cost to Install an Electric Shower?
Getting an electric shower professionally installed can cost from £150 to £300. However, this can jump to £700 if you have a high-end unit.
But, which trade actually installs an electric shower?
You can contact either a plumber or electrician who should both be experienced and able to fix the plumbing. But, you will need a Part P-certified electrician to test and sign off the electrics.
If you are just replacing the electric shower, a plumber may be able to fully install the shower as the electrical cables are already there.
