ok you will need your nappies, liners can either be disopsable or fleece. and you will need some outer waterproof wraps.
you can store the dirty nappies in a big nappy bucket, or a big waterproof bag. you don't have to soak, you can put them in as they are and just add some tea tree oil to combat smell!
for dirty nappies just tip the solids into toilet and rinse them.
I would recommend using fleece liners, simply because the moisture will wick away leaving a pretty much dry surface next to baby's bottom.
some people prefer paper ones though because you just chuck the whole lot down the loo!
you can put nappies in with your ordinary washing, but remember they may need washing on a higher temperature, and you musn't use fabric softener.
