I'm concerned by most of the advice in this thread - not just the
above. There coule be a live to earth fault and no bathroom bonding
for all we know.

How do you deduce that from the symptoms described?

what we can deduce is that that is one of the possible scenarios. We
can not deduce which scenario is definitely the one, the shower
install will need to be tested to determine and correct the fault.

If the above scenario is what the OP has, which is possible, fitting a
45A fuse might result in death.
