Exposed shower systems are mixer showers that need a hot and cold supply and all the workings are on the outside of the wall. The showers valves are normally thermostatic (which means that the temperature is constantly regulated & controlled in case of any interruptions to the hot or cold water supply). Manual showers are the opposite and don't have a constant temperature control.

They are favourable for solid walls due to their ease of installation on the outside of the wall as only the water supply pipes need chasing into the wall. Spare part cartridges are easily accessed by removing the handle/knob for maintenance. The majority are 150mm pipe centres for installation which means any model should be relatively easily replaced with any brand if a whole new system is wanted.

In our online bathroom store, you can normally either have a single handset on a slider rail or a combination with a large drench head above as well. 

Concealed shower systems are also mixer showers that use both hot and cold water supply and all the workings are on the inside of the wall. They are mostly thermostatic (which means that the temperature is constantly regulated & controlled in case of any interruptions to the hot or cold water supply). Manual showers are the opposite and don't have a constant temperature control.

They are favourable for stud walls or require false walls due to the main body of the valve which fits into the wall. Spare part cartridges are easily accessed by removing the front knob for maintenance. An advantage of this valve is that it can be placed in a different location to the shower heads meaning you can turn the shower on without getting your hand wet.

You can have a massive selection of different combinations of single handset on a clip or a slider rail or a large drench head above as well body jets and even bath fillers in our bathroom showroom. Mainly available in 1 , 2 or 3 functions.

Electric showers run off cold water only and require an electrical supply. The higher the kilowatt rating the higher the flow rate with the shower but speak to your electrician as there might be complications with your electrics and consumer units.

The electrics heat up the cold water which means it would still work if your boiler fails. These are normally only a small handset on a slider rail due to the low pressure and flow.

Digital showers require both a hot and cold water feed and an electrical supply. There is normally a separate console that these supplies feed to which can be located in a accessible location such as in a loft space or in cupboard near the bathroom. This then has the mixed water supplies running to the shower heads or bath fillers. The controls are more like remotes which either have a thin wire or are wireless (battery operated). This is an advantage if you want a concealed shower but can't have the  location of the valve due to a solid wall.

You can get pumped or no-pumped (for high pressure systems) models to give you the optimal showering experience. They are normally 1 or 2 function (feeding one or two heads) and you can sometimes get an additional remote.

Being a digital product with a CPU (computer) has additional benefits such as time display, timer, user presets, exact temperature display. 

Power showers are exposed mixer showers (with a hot and cold water feed) that also have a small pump inside the main box unit to boost the pressure which means it would require an electrical feed. They tend to only have a slider rail kit and handset (no overhead shower). You can get both Manual (no constant regulation of temperature) and Thermostatic (constant regulation of temperature) versions of these. 

These type of showers are reducing in popularity in the bathroom market as many new boilers being fitted run high pressure systems. Also Digital showers can be a preferred alternative as although more costly, they can look a look smarter (no big box on the wall in the shower) and have the option for additional drench shower heads or bath fillers.
