document demonstrate techiques that have been standard or are slowly
becoming standard most everywhere in the past 30 years. This was
required in North America starting about 1970. Best way to address
electric safety starts by not worrying what you do or do not use in the
bathroom. That picture of a human in a bathtub using a hairdryer to
blow a sailing boat is what you - the owner of a building - must
address.

Hair driers used in baths was a US-specific problem.
We had put rules in place to prevent that before WWII.
Even other countries which still haven't don't have the
same problem the US did with electrocutions in baths.

Start by putting all incoming electrical service on a GFCI - also
called RCD. One that trips at leakage currents lower than a building
wide RCD. These 'one circuit' type RCDs should trip at something
around 10 mA. This mA number will vary with different countries and
codes. But any bathroom with electricity should have a dedicated
GFCI/RCD type protector regardless of whether required by local codes.

You are wrong on just about every count here with regards
to UK regs.
