All seemed to be well. No more drips. Until today. The lady of the
house had a big shower (why does it take so long to wash hair?) and
there's a proper little stream coming down into the kitchen. It seems
to be coming from the same place, but my new grouting and sealing looks
fine. The adjacent bit of wall is not pristine, there are hairline
cracks in some of the grouting, but it doesn't look bad enough to allow
that much water through.

So how invisible can a gap be and still let water out? I really don't
want to re-grout the whole damn thing. Also, and tips for pinpointing
the leak would be appreciated (I'm thinking fluorescent dye or
something).

If you can see a crack in the grouting you can bet water can get through.
Try directing the shower spray onto it with someone weatching from below
and wait for the shouts of alarm as water comes through!
