Why do houses have a switch to turn the shower off, either a cord on

Can't be for safety - 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.

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

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

If I answer this, do you promise to **** off?

It's so somebody not in the shower can isolate it quickly before helping
the poor bugger who is being electrocuted.

And how many times has this ever actually happened?

And why are we therefore not forbidden to have showers when nobody else is
home?

And why can't they make showers which are guaranteed not to electrocute
you?

Most of the world does not use elrctric point of use heater
"widowmaker" showers.

Most do allow what are usually called instant electrical hot
water heaters on showers as an alternative to stored hot water
that is heated electrically.

Widowmakers are a different thing entirely with
an electrical element in the shower head itself,
with the electrical connections to the element
actually in the water. Those are in fact allowed
in quite a bit of europe.

And why can't the other person just switch the shower off on its own
switch?
