Ah ok... as the others said, the neon beastie will not tell you much
other than you and the screw are at a different potential. But you
knew
that from the tingle ;-)

It takes something like 80v to light a neon. Whether the liveness is
coming from the screws or the floor the OP is standing on, either way
theres a problem. Although neon screwdrivers have their problems, this
would not be happening if all was well.

At best the OP has a few bits that ought to be earthed but arent, and
are passing feelable leakage. At worst the whole system may be a real
danger. I wouldnt use the electric shower until its sorted!
