I am more concerned about the fact that your electric sockets are in a bad spot, immediately under a sink, as far as I know, there should be no electrical sockets within a meter or so of any sink, (the electrical safety regulations, latest edition may dictate a different distance) However, its not the fact that the sockets are underneath, and are not readily accessable, but imagine if any of those flexible hoses split and starts jetting water directly towards the sockets, and or if the sink top to wall joint develops a leak and the water starts running down into the sockets, this is the water that splashes when you are using the kitchen sink and can run along the wall straight into the sockets, if the wall joint became bad over some time,. So I would take some steps to move them somewhere else more safer, or make some splash proof covering, and may be fit someting to stop water getting into the sockets if should the sink top seal ever leaks water, so it would be deflected away from teh sockets. this is all from the electrical safety point of view.
