Water flow rate

How we test water flow rate

We measure the amount of hot 40°C water that's delivered through the shower head in one go. In general, the higher the wattage of the shower the more hot water it will produce. Showers scoring five scores produced around a litre more per minute than models scoring three stars.

Temperature stability

Overall
Stability on high setting
Stability if the pressure drops

How we test temperature stability

We test to see how well the shower can maintain a 40C temperature if someone else uses the water supply at the same time.

Ease of use

How we test ease of use
