How to Install and Fit an Electric Shower

In need of a new electric shower? Has the old one malfunctioned, or are you making a change from the traditional boiler-operated models? Regardless of why you want an electric shower, the big question remains: how do you install and fit an electric shower? This guide is here to answer all your questions with detailed visual guides, as well as answering some of the most frequently asked questions on the topic.

How to Prepare to Install an Electric Shower

There are a couple of things to remember when you are preparing to install your electric shower:

  • They have a minimum water pressure requirement in order to work, and will also have a minimum flow rate on top of that
  • Check your measurements for the handset and the height of the shower box. Can the whole family use it?
  • Clean the area before you install so that you don’t risk cluttering the place further, slipping on soap, or making toothbrushes manky.

What Kind of Electrical Requirements are There?

The electrical requirements are a little complicated, but nothing that you can’t get your head around. The cable and fuse sizes will vary according to your home and the type of shower you are looking to buy. Therefore, we would recommend a 10 sq mm cable as this means you are less likely to need to replace it in the future. Look at it as the universal shower cable.

The electrics will need to be connected to a separate fused electrical supply. You will also need a ceiling double-mounted pole switch for safety (the long cord in your bathroom near the shower). This turns the supply to the shower on and off quickly when needed.

What Kind of Plumbing Requirements are There?

The plumbing requirements are very simple. You will need a mains plumbing supply, and it should ideally have a 15mm pipe (diameter) for the best fit. Other than that, nothing else is needed from the plumbing side of the process.

Are Some Electric Showers Easier to Install Than Others?

Yes, some electric showers are definitely easier to install than others. The simplest ones have multiple entry points for the pipe to be fitted, allowing for a more flexible installation process that requires a lot less fiddling around. Similarly, swivelling water connections are ideal, and they should have plenty of room for the spanner to be placed and used.
