current regs say pipes should be bonded to each other in central area, not necessarily in bathroom could be in adjacent airing cupboard say, but if current consuming items such as electric towel rails then they must bond to all pipes in room but as 2008 17th edition regs will not require this don't worry!
All metal fronted fittings must be earthed to circuit earth but if you mean metal back boxes then regs. Never did require them to be bonded ie have 'pig tails' from circuit to box. this urban myth was started by a certain trade organisation misunderstanding reg. 543-02-05 & 07, which say you can use metal conduit for circuit earth, but if you do then an earth wire must go from back box to accessory, sorry to go techy but lots read these posts,
