pme is probably the problem. this is the result of small diverted neutral currents causing perceived shock. It is a relatively well documented phenomenon that people showering in leisure complexes connected to pme earths often feel a tingling sensation. It is often cured by ensuring that a metal floor grid is installed which is connected to the local supplementary bonding arrangements. Many designers will ensure that such facilities are not connected to a pme terminal but are TN-S or TT.
I take it that Paul is right when he assumes the water is flowing and the client is touching the bath while standing on the floor.
I should also say dont discount other possibilities. Remember a spark a few years ago got six months for negligence in just such a situation. A girl was electrocuted at a kitchen sink after reporting shocks as she used the kitchen sink. Poor old sparky investigated but was beat and put it down to static. It turned out that there was an intermittent earth fault om central heating timer. So I give my diagnosis only by way of technical chat and suggest that you dont let the matter go unresolved! Good luck!
