Power showers work in the same way as mixer showers in that they combine water from the cold and hot supplies. The difference is that power showers have a built-in pump. This strengthens the flow – great if your home has low water pressure – and also offers you greater control over the temperature and pressure than a normal mixer shower.

Power showers are designed to work with gravity-fed or low-pressure water systems, instantly boosting the flow and resulting in a more invigorating shower.While installing a power shower is less fiddly than buying a separate pump to boost a standard mixer shower, they do use a lot more water than electric showers, so bear this in mind if you have a water meter.
