I honestly don't know why all showers aren't like this (I don't need bed-based activation, it only takes a few seconds). Select temperature, wait, get in. Yet everywhere I go, it's still the random bloody mixer taps, endless jiggery trying to get the right temperature and then, thirty seconds later it goes hot, cold, hot, cold, or you inadvertently activate the scald/freeze feature with your arse because the tap is right there.
Hotels were terrible for this, every new stay came with the first-morning horror of figuring out the shower.
