RE: To cross bond or not to cross bond
If you have a line of sinks in a public toilet for example you would not need to cross bond under each, you would however need to make sure that they are bonded such that there is no potential difference between any mutually accessible conductive parts.

RE: To cross bond or not to cross bond
The 15th Edition of the IEE Wiring Regulations required supplementary bonding to be applied to all sinks where extraneous-conductive-parts were not reliably connected to the main bonding, and many examples still exist today. This requirement was deleted in subsequent editions of the Wiring Regulations and it is not required by the present Standard, BS 7671.
