Oh yes, and showers. Don't install over-designed showers than needs a degree in hydro-engineering to work out how to turn on and and get water of the right temperature. All we need is on, off and temperature. On occasion I have given up trying to work out how the shower worked as there were so many knobs, switches and levers.

I'm only going to be in the room for a night or two. I'm going to be half asleep (and possibly hungover) when I used the shower and I won't have my glasses on. I don't have time to go on a Shower Usage Induction Course.
