You already have a cold water supply to your hot water tank, so why
not tap in to that?

You really haven't a clue. Please do not give advise on fields you
know nothing about. The cold for the shower comes from the cold tank.

Whereas the cold feed to the hot tank comes from . . .yes, you've guessed
it
. . .the cold tank!

Having said that, the shower really does need a dedicated feed from the
cold
tank - and not one shared with the feed to the hot tank. It also needs to
be
taken from a *lower* point than the cold take-off to the hot tank so that,
in the event of the cold tank emptying, the hot stops running first.

So a new and dedicated pipe from the cold tank would continue to supply cold
water, even with the cold tank empty? Oh right. Both hot water cylinder
and cold water tap supplies are from the same cold water storage tank. The
pressures to all the taps and appliances will all be equal, barring stupid
forms of pipework of course. So I don't see any need to complicate the
supply to one single new appliance that is being added to an already stable
system.

Where do you people live? :-)
