Would it be ok to run the earth bonding from the pull switch...down the wall behind capping and tiling...to under the bath where ALL heating and water pipework comes out of the wall from the cylinder in the adjoining bedroom where the airing cupboard is sited? This is also the wall where the new electric shower will be sited...coming directly thru the wall from the airing cupboard.
OR...will I have to run bonding to other appliances?
