We are refitting our bathroom and need a thermostatic mixer shower. Although it will be mains pressure via combi boiler, our water pressure is rubbish-and we do like a powerful shower. I’ve read that Mira showers do very well with limited water pressure-is this true? The excel looks good but is £££. We don’t mind if it’s worth it. Are Aquilisa a decent brand? Have been told to steer clear of German showers as they need a very high pressure to work properly. Advice please mumsnetters….
