Electric Shower Buying Guide

Electric showers are the rage in the market right now.

When you install one, they help you heat your cold water so you wouldn’t have to wait a long time for your water tank or heater to heat up before you can shower.

And you won’t be incurring more expenses in your energy bills because they heat minimal amount of water and only at the time of your shower.

All you need is cold water and you are ready to shower and install an electric shower.

How Powerful Are Electric Showers?

Unlike power mixers or power shower, electric showers often come with a poorer flow so you shouldn’t expect a fountain of hot water for your shower. The power of electric showers ranges from 8.5k W to 10.5k W.

When you purchase a model with higher wattage power, the amount of water that can be heated and pass through the shower head at a time will be greater than that of a less powerful model.

There are many reasons you may want to get an electric shower on the higher end of the power spectrum – such as being able to wash shampoo off your hair quickly or not having to waste time on a morning shower. The only hindrance is the cost goes upwards along with the wattage power.

Who Should Use an Electric Shower?

If you have a cold main water supply in your home, you can install an electric shower. They are not affected by the type of water you have in your home and you can use them in unheated rooms or in a converted garage with storage heater.

If you are installing an electric shower in a new building or structure, then it will be useful. However, if you are looking at an existing structure, chances are that you already have sufficient water pressure and a good shower system in place.

Generally, electric showers can be installed in any home because they are completely separate from your hot water system. This is because they have an internal heating element that takes water from your cold water supply and heat it up as you shower. The process is very quick and the more wattage a unit carries, the faster the process.

How Should I Install the Electric Shower?

There are only a few ways of installing an electric shower. However, some questions might come up as you think about where and how to install your electric shower such as:

When you are replacing an old model with a new one, you shouldn’t have any trouble swapping out the old one for the new one, provided that they both have compatible power cabling connection. Moreover, newer models have multiple power and water inlet options that make it easier for you to install them especially if you are replacing a brand different from the new one.

What Features Should You Look Out For?

There are a number of features you need to pay attention to if you want to get the right one for your needs.

The first one is the thermostatic feature. A thermostatic shower will keep the temperature of the water within a threshold degree so that the water doesn’t become too hot or sleep-inducing cold when the cold water main is used elsewhere in your room.

Another feature is the phased shutdown. This feature allows the shower to automatically run cold water for some moments after you have shut down the shower. This will help to prevent the buildup of limescale – a laky deposit that can sit in your shower which can result from the effect heat on water with calcium salt.

Adjustable riser rail brackets are useful when you are replacing an existing shower. Instead of drilling new holes on the wall and disfiguring your bathroom, you can make use of adjustable riser rail brackets on the existing holes to install the new electric shower.

You should also consider purchasing a model that has a multiple power and water inlet options so that it can be easier to install. Be aware that these types of showers may cost more and you may need to do some comparison shopping to get the right one for our bathroom.


The installation of electric shower can be quite tricky as it has to be connected to your home’s main electricity and hooked up to a cold water supply and a ceiling-mounted switch where you can switch it on and off safely. It is recommended that you always outsource the installation to a professional who will do this perfectly for your home.
