Taps
Bathroom taps are always separate for hot and cold.
No, they are not. Why is this such a problem anyway?
My bathroom wash basin (not sink, that’s in your kitchen) has a mixer type. Everyone I know has mixer taps. I am looking at a supply catalogue and they are mostly mixers.
Baths could possibly be two separate taps. It may be that there are people with separate taps on their basins. We have seen this in the USA too. People just have what they want. It isn’t a British ‘thing’ anymore than it is anywhere else.
