Have an old electric shower - at least 10 years. No idea of its power
rating but it's always worked well enough in the summer - didn't use
it in the winter as it couldn't get the water up to a decent temp.

Anyways - having aquired a significant other, suddenly it's getting
maoned about. First question is - is it worth replacing - in the last
10 years have electric showers got better. Second question - how easy
is it likely to be to replace - the pipe into the existing shower
seems to be the same width as all the other pipes in the house and
I've done odd bits and pieces on them over the years with 'standard'
fittings - the electric cable comes in via an external switch to
isolate it. Could I resonably expect a new show to fit where the old
one was without a lot of trouble?

Finally - any particular recomendations - guess I''ll get a 9.5kw
version - but all these showers come with a range of whistles and
bells and huge range of prices - what whistles and bells are worth
having and what r just a waste of money??

TIA
