Opting for the highest kW rated electric shower isn’t necessarily the best choice for your home. Before choosing a powerful system such as a 10.5kW unit, you want to ensure that your consumer unit has the required amount of amps to support it. Failing to meet the amps required to run the powerful electric shower can result in power outages.

Popular power options include 8.5kW, 9.5kW and 10.5kW systems where the prices increase with the higher kW rating. Although the powerful electric showers cost more, the greater flow of water provides a more luxurious experience.

After plenty of research and experience installing a range of electric showers, we concluded that the best electric shower is the Triton Seville. It’s an affordable option that’s available in a variety of power options to best suit your requirements. It also has a versatile design for matching up with your existing plumbing and wiring for an easy installation. However, if you are willing to spend a little bit more, the Mira Sport Max is the best premium alternative.

In terms of rating the electric showers within this article, we based our recommendations upon our own experience of installing multiple systems as well as various factors. The factors that were considered included their performance, spray patterns, ease of installation, styling, features, additional components included and value for money.

How We Rated The Electric Showers

In terms of rating the electric showers within this article, we based our recommendations upon our own experience of installing a range of electric showers. We also considered a number of factors that included their performance, spray patterns, ease of installation, styling, features, additional components included and value for money.

As we own a number of properties, an electric shower is a product that we’ve replaced on multiple occasions. As you can see from the below photo, we installed the highly rated Triton T80, which was very straightforward to fit and provides great performance for the money.

Electric Shower Buying Guide

Showers that output low pressure at high temperatures can make showering an unpleasant experience. Upgrading to the latest and most efficient electric shower systems can make a huge difference. They are available in a range of power options to suit your home with the higher kW ratings being more desirable.

Considering that you will shower at least once a day, investing into the best electric shower is a worthwhile investment. They have improved a great deal over the years with manufacturers competing with each other to bring the latest features and functionality.

To help you make an informed buying decision, we have produced the below guide regarding electric showers.

Safety Regulations

When dealing with electricity, it’s important that safety is paramount. Before you install an electric shower, you will want to ensure your consumer unit can support it.

High kW showers will use a lot of power, which many consumer units may not be able to handle. Therefore, you will want to check that the cable and protection device is suitable for the electric shower you choose.

Installing or Replacing an Electric Shower

Installation of an electric shower can be achieved by yourself or a professional. The labour cost that a professional may charge will depend upon their hourly rate. Installation of a brand new electric shower may take around 6 hours whereas a simple replacement may take just 3 hours.

When it comes to the installation of an electric shower, you will want to consult both an electrician and plumber. Mixing high powered electricity and water isn’t a good match. If the wiring and water supply have already been installed, replacing the electric shower can be a simple DIY task.

To replace the old system with one of the recommendations listed above, follow the 10 steps below:

  1. Disconnect the power supply.
  2. Switch off the water supply.
  3. Remove the old unit that hold it onto the wall.
  4. Remove the front panel of the new unit and check the water supply connections.
  5. Place the new system where the last one was fitted and mark up new holes to screw into.
  6. Drill into the wall using the markings and insert rawl plugs.
  7. Connect the neutrals live and check the earths are installed correctly.
  8. Connect the water supply.
  9. Turn on both the power and water supply.
  10. Thoroughly test by using all the functions and temperature settings.

Replacing an electric shower as opposed to installing a complete new system is far easier. Unless you know what you are doing, we would advise that you contact a professional to avoid all of the hassle.

Power Options

The main specification of an electric shower is the kW rating. The most common options include 8.5kW, 9.5kW and 10.5kW. We highly advise that you choose systems that are 8.5kW and over to ensure that you always have a hot shower.

Choosing a powerful electric shower such as the 10.5kW will allow you to run higher pressure at higher temperatures. The drawback is that there will be more water usage and they are generally more expensive to purchase. If you have low water pressure in your house, your best option would be to choose a power shower with a built-in boost pump.

The low powered eco-friendly electric showers flow slowly past the heating element in order to heat the water. This means that there is less pressure at higher temperatures. If you have an unreliable water supply or small water tank, the low powered alternatives are the best option.

Phased Shutdown

To help improve the longevity of the system, some brands integrate a phased shutdown into their systems. This means that the water will continue to run for a few seconds after it has been switched off. The purpose of this is that it allows any water left in the system to drain out, which reduces lime scale in the heater and shower head.

Temperature Stabilised and Thermostatic Systems

Water that fluctuates in temperature whilst you are showering can be highly frustrating. The fluctuations can be caused by a toilet being flushed or the tap being turned on. If this is something that you find very irritating, you will want an electric shower that features temperature stabilising. It controls the water temperature but it cannot always be constant.

Thermostatic electric showers ensure the water temperature remains constant regardless of the water supply. It’s often the preferred option over a temperature stabilised system.

Ease of Use

Using an electric shower shouldn’t be complex to use. The majority of systems will have a rotary dial for controlling the temperature with some having an intuitive digital display for showing the selected temperature. Stopping and starting the shower usually differs as some may use a push button whereas other may use another rotary dial.

Benefits of Choosing an Electric System

Installing an electric shower instead of a standard system has various benefits such as:

  • Easier installation
  • Endless hot water supply
  • More versatile
  • Energy efficient
  • Independent from hot water supply

If you are lucky enough to have an en-suite or additional bathrooms in your home, the best option is usually to install an electric shower. This is due to the ease of the installation and limited plumbing required.

Top Electric Shower Brands

Purchasing an electric shower from a reputable brand is highly advised. Not only will there be spare parts and accessories available but they often have better warranties. Some of the brands that we would recommend include:

  • Triton
  • Mira Showers
  • Bristan
  • Aqualisa
  • … and a few others


Installing an electric shower as opposed to a standard shower can be beneficial if there is no existing plumbing. All that’s required is the addition of a cold water supply to the electric shower. Also opting for a higher kW rated system will provide a hotter and stronger shower, which is highly recommended.

All of our recommendations above are suited to a range of budgets and are manufactured by the best brands in the UK. To avoid disappointment, before purchasing any electric shower, ensure that your home is able to support it.
