Because that's how your stupid regulatory

At least you agree it's stupid.

Can't be for safety

Fraid so.

But it doesn't make anything safer.

- if you're in the shower and get a shock, if you've managed
to get out to reach the switch, you've got away from it anyway.

Its done like that for the other situation, so you
don't get out of the shower dripping wet and use
the switch dripping wet and get a shock that way.

What switch? I'm, saying there shouldn't be any external switch anywhere. Everyone turns the shower off on the shower itself while they're still in it.

Can't be to isolate to work on it, there's a fusebox for that.

Correct.

Don't need to turn it off when you're finished
showering, there's a switch on the shower itself.

But that's one that can be safely used dripping wet.

And so can the one on the shower, because that's already splashed to hell while you wash. So if you want to adjust the temperature, do you actually get out, turn off the isolation switch, then change the temperature, then turn it back on and get back in? The controls on a shower are waterproof!
