Choosing an electric or power shower installation depends on what type of water system you have. If your cold water comes directly from the mains or you have a combination boiler, then you can choose between a mixer shower without a pump and an electric shower.

If you have a gravity-fed system (a cold tank in the attic and a hot water cylinder in the hotpress), you can choose between a power shower, an electric shower, or a mixer shower with or without a pump.


Electric. Electric showers heat water on demand, taking it from the mains cold water supply and passing it over a heating element inside the shower unit. …

  • Mixer
  • Thermostatic
  • Digital
  • Gravity Systems
  • Combination (Combi) Boiler Systems.


  • Electric showers are one of the most versatile types of shower available. They are very convenient when you want an instant hot shower.
  • They are efficient as they only heat the water used.
  • They generally are cheaper to run as they use less energy, less water and heat up quickly.
  • Electric showers work much better if you have a gravity-fed system (a cold tank in the attic and a hot water cylinder in the hot-press)
  • Electric showers take water from your cold-water supplies.
  • They can use an electric pump to increase water pressure. However, they rely on the pressure of your mains supply of water and you cannot connect to a shower pump if you have a combi boiler system.


  • A mixer shower mixes a hot water and cold-water supply to a chosen temperature.
  • They can work with either low or high-pressure supplies.
  • Unlike power showers they do not use a pump system and will not increase the low pressure of a water flow.
  • If your supply of hot water is plentiful and has a powerful flow mixer showers gives you more of a boost than an electric shower.


  • A thermostatic mixer prevents any sudden changes in the water supply or temperature to the shower.
  • It maintains an exact water temperature for the duration of your shower.
  • As the thermostatic shower only uses hot and cold water as needed in the long run your water-heating bill should be reduced.


  • Digital showers use electricity to run a thermostat to control water flow and temperature. They are easier to control and more accurate when it comes to water temperature.
  • Ideal when you are running late and in a hurry as there is no waiting for the water to heat up.
  • A digital shower has a digital thermostat within the shower unit. The thermostat controls the water temperature and ensures that regardless of what other appliances are in use in your home you do not have any changes in water temperature in your shower.
  • Digital showers are controlled by the thermostat and are more accurate than mixer showers in ensuring there are no spikes in temperature.
  • Combi-boiler heating systems will only work with digital showers.


  • Gravity fed showers receive water from your cold-water tank in your attic and from your hot water cylinder in the hot press.
  • Gravity fed showers receive water under gravity and mixes them together to reach the desired temperature.


  • Combi boilers are dependable across electric, digital and mixed showers and run off the mains pressure.
  • They are mains fed and so you cannot use a pump to provide a boost to the water pressure.
  • To ensure that your combi-boiler is powerful enough check the flow rate – it needs to be at lease 12-15 liters a minute.  The bigger the shower head the greater pressure required.

The majority of the cost of a new shower installation is due to labour fees. And while you might think you’ll save some money by having a go at doing it yourself, you may end up paying more in the long run. Repairing a botched job usually costs a lot more to put right than getting it done right to begin with.

It typically costs about €950.00 plus vat @ 13.5% to supply and fit for a brand new electric shower. This price includes all the piping necessary for your shower installation.

If you already have an electric shower in place, but its not working, it can usually be more cost effective in the long to replace it. The cost to replace an existing electric shower, usually costs €450 plus vat @ 13.5%.  These prices are based on supplying & fitting Trition T90 or Mira Elite, which are the brands and models of electric shower we recommend.
