According to my on site guide, Zone 1 SELV allowed, Water heaters, showers,
shower pumps allowed. other fixed equipment that can not reasonably be
located elsewhere allowed if protected by a 30mA RCD.

SELV stands for "Safe Extra Low Voltage" LOZ34, so anything that runs on a SELV system
is more than likely running through an isolated step down transformer to give the low
voltage and ampage needed to be within "Zone 1" of a wet room area. The point of the
SELV rating is to allow electronic equipment to be in an area where it might be
directly splashed or come into contact with high amounts of water or steam. I don't
fancy splashing water on a mains powered item while I'm standing in the bath. :-))
