I use a bin I got from pets at home. It is meant to store cat food or litter in. I have 2 in nappies and it is perfect size. Can fit 1-2 wash loads in it. I hate the tiny ones that come with sets of nappies.
I have been having this problem recently. I used to have the 14L one for normal nappies, and a slighly smaller one for wraps, coloured nappies etc (ones that couldn't be washed at 60) but now I just use that as an overflow bucket if the main one is full to the brim.
Sorry, that is not very useful I know!
DH has an annoying habit of just putting an used nappy on top of the nappies in the full bucket and then just putting the lid 'balanced' on top of the nappies (so no sealed down lid basically). Have told him that there's no point having a lid if he does this
I had exactly the same problem so I got a white flip lid bin from Ikea, can't remember the name but they come in three sizes and I got the middle size. It takes a whole wash load of nappies. Cost about £6.
Thanks guys, I have tried Wilkinsons but couldn't find anything with a decent closing lid, will try Pets at Home and B&Q. Failing that maybe I could persuade DH that we need a trip to Ikea... unlikely methinks!
