I am in the process of planning a kitchen extension and would like to install an island unit which contains the sink and a dishwasher. If the floor is concrete what is the best way to get services (water, waste and electricity) across to the island. Do I need to bury a plastic service pipe through which everything can run? I suspect a similar problem will arise with piping to the central heating radiators.
As you will have guessed I have little or no experience of dealing with concrete floors. The rest of the house has a suspended wooden floor with services running under it. Should I do the same in the extension?
