I am planning a style change to my bathroom that involves replacing the
taps and shower mixer.

Taking that the gap between the entry pipes, hot and cold, is the same
on the new unit is replacement just a matter of isolating supplies,
detaching the existing unit and fitting the replacement or will I need
to make holes in my walls to access the pipework.

The more often you ask the question, the less likely you are to receive
a worthwhile reply.
