You can buy 8 kW showers - but I wouldn't bother!


I've got an 8.5kW shower, and find it perfectly fine. Admitadly, it's
nothing compared to a power shower, but it is certainly better than the old
6.5kW one at my Dad's house

depends what you're used to.

My brother has very high water preasure throughout his house, and using the
shower there is like using a jet wash
