Shower Selector Tool

Welcome to the Shower Selector process.

Step One: Identify Your System

Certain showers will only work with specific types of household systems. Below are a selection of systems common in most households, identify which system your using and click the 'Choose System' link to continue to Step Two.


Choose Gravity SystemChoose Combi-Boiler System
Choose a Pumped Thermostatic Mixer ValveChoose Mains Fed Electric
Choose Pumped All-In-One Power Shower Gravity FedChoose Mains Unvented


Digital Showers

Digital showers can be used both off the mains water supply via a combination boiler, or on an unvented heating system (see for further information) They can also be used via a conventional gravity fed system, using stored hot water and a cold water tank, please refer to the schematic drawings under the Showerselector process to understand how these systems look, as they will help you identify your own system.

Pumped digital showers essentially take your stored hot and cold water, mix it, then pump the mixed supply of water to the shower, via a digital interface in the shower area.

Non-pumped digital showers work via a combination boilers or on an unvented heating system, effectively using the mains pressure, which is generally much higher than can be achieved via a gravity fed system. This means there is no need for an integral pump in the mixing unit.

Digital showers are widely recognised as the future of showering in the UK,  Showerselector features the leading UK brands such as Mira, and Aqualisa, two of the leading exponents of digital showering.


Electric Showers

Electric showers are connected via the rising cold main into the property, please refer to the schematic drawing under the Showerselector process ,to help you understand the principle of how an electric shower works.

The performance of an electric shower is dependent upon various criteria, the kW rating of the shower used (ie the power of the unit) the flow of water/pressure coming into the unit, and the incoming cold water temperature.

Electric shower kW power ratings vary from 7.5kW up to 10.8kW, and generally speaking the higher the kW rating the greater the pressure and flow of the shower.The most common kW rating used in the UK, is 8.5 to 9.0 Kw, as a rule of thumb the following would apply:

7.5kW – Adequate shower in summer months but poor performance in winter when the ambient temperature of the cold water is very cold, and therefore more kW of power is needed to heat up the incoming water as it passes over the elements in the hot water tank of the shower.

8.5 - 9.0kW – Good shower in summer, and adequate shower in winter, making this the most common electric shower power rating used in the UK.

10.0 - 10.8kW – Excellent shower in the summer and good shower in the winter months, due largely to their high power rating, 10kW plus power ratings provide the best in electric showering, check out the Mira Sport 10.8 max for the ultimate in electric showering in the UK.Two of the leading electric shower brands in the UK are Mira Showers and Triton Showers,which we sell at highly competitive prices.


Mixer Showers

Mixer showers can be used both off the mains water supply via a combination boiler, or on an unvented heating system (see for further information) or via a conventional gravity fed system using stored hot water and a cold water tank.

Please refer to the schematic drawings under the Showerselector process to understand how these systems look, and to help you identify your own system.

Mixer showers essentially take your stored hot and cold water and mix it via the mixing valve.

We recommend thermostatic mixing valves, these valves have an integral thermostat, the thermostat ensures a safe showering temperature for users, especially important for the very young or indeed the very old.

Showerselector recommends the use of thermostatic shower valves as standard.

Showerselector recommends Mira mixer showers – they are designed specifically for UK plumbing systems,  with their high level of engineering that delivers good flow and pressure through the mixing valves.The range of pricing varies from £100 to £300+. 

The choices of mixing valves are numerous largely around styling or price point, clearly the more expensive the better the design and engineering of the product.


Power Showers

There are two types of power shower, both of which utilise stored hot and cold water.  The stored hot and cold water are effectively mixed together and then passed through a pump which then significantly improves the performance of the shower ,through increased pressure and flow to deliver the ‘power shower’.

The most cost effective power shower is the ‘integral’ power shower, where the power shower unit houses both the pump and the mixer shower encased typically in a white plastic unit, not dissimilar in looks to an electric shower.  They can be noisy if not fitted in the right location, for instance, because of the integral motor and pump they should not be installed onto a cavity wall.

Showerselector recommends the Aqualisa and Mira ranges, which suits all budgetary and aesthetic needs.  Again, Showerselector recommends thermostatic units.

The other Power Shower configuration available is the arrangement of a shower mixing valve such as the Mira Excel, which mixes water via a conventional gravity fed system with stored hot and cold water which is fed then through a shower pump, such as the Salamander range or Stuart Turner range. Once pumped, the hot and cold water then supplies the mixing valve with heavy pressure and flow.  Ideal for those who like strong performance in their shower with a well designed shower mixing valve in the shower area.


Shower Pumps

Showerselector recommends both Salamander and Stuart Turner shower pumps, the two best selling shower pump ranges available in the UK.Salamander are probably the most cost effective and best value range of shower pumps.

Showerselectorrecommends twin impeller shower pumps, twin impeller meaning the pump has two sides to it and two sets of impellers, one side to pump the cold water and the other the hot water from stored supplies in the home.

Shower pumps range from 1.5 bar up to 4.0 bar plus, typically, a 1.5 bar twin impeller shower pump will give a strong individual shower performance.  If another outlet is required such as a bath tap, then a 2.0 bar or 3.0 bar pump will be required.  If a shower has multiple outlets such as bodyjets, then 3.0 bar + pumps will be required.
