Honestly lad, the first thing I'll say is that when it comes to anything involving bathroom circuitry or wiring to consumer units, if you need to ask for help then you shouldn't be doing it in the first place.
Secondly, I'm not a qualified electrician so take my advice with a pinch of salt whatever you do.
If you're committed to doing this, the first rule you need to know is that any electrical socket in the bathroom has to be at least 3m away from any bath, shower or sink.
Also bear in mind... If you sell the house, at some point there will be surveyors along to inspect it before the mortgage goes through, and if your work isn't 100% perfect it could bite you in the arse.
Get an electrician to take a look, at the very least just get a quote before you start anything yourself.
