Made this mistake in the bathroom. When I refurbished it, I wanted the taps at the other end wall so I rotated the new bath and taps 180 degrees, reconnected, never really thought about it.
A few years later the hot was dripping, needed a new cartridge. No problem, ordered it, took the old one out....eh, its a blue insert, cold. I'd forgot to switch the feed pipes.
Tbf, my kitchen sink is the same. No idea when or how it happened, but it's all OK, just different.
Occasionally, a visitor will say...your taps are the wrong way round ?
