Then you must be shot down in flames because what you are proposing
clearly violates the wiring regulations (BS 7671). Supplementary
bonding to exposed-conductive-parts (and therefore the CPCs) of
electrical equipment in a bathroom has been required since coming of the
14th edition of the IEE Regs (c. 1966). When the revised Section 601
(bathroom rules) came in to force in 2000 this was modified to require
bonding to the CPCs of *all* circuits feeding equipment within the
zones, _whether_or_not_ there are exposed-conductive-parts. Thus you
must still bond to the relevant CPCs, even if Class 2 equipment is
installed. This is clearly intended to provide for safety when
equipment is subsequently changed.
