It's not in the regs., and as far I can see it's worldwide

Cold taps came first and as 90% of the population are right handed the
obvious place for the cold tap is on the right. Having the hot tap on
the left also helps the wimps in the UK as the hot tap is still often
low pressure and easier to turn off.

my cold tap in the bathroom is on the left, because I hold my toothbrush
with my right hand

Actually, IIRC, it made the pipe runs easier

I'm not going to lose sleep over it
