I have an XL wetbag hung on the back of K's bedroom door...everything goes in there and we dont ever gets smells I havnt ever had a utility room either...would be lovely though!!
Our nappy bucket is kept in MAx's room as that is where we change him. Its only small and so I wash every other day. I use tea tree and/or lavender oil in the clean bucket so don't really get bad smells.
Would love a utility room tho as there is definitely no room for one in our current house
Mine was a big bin in the kitchen, only prob i had with it was if people came around they would put rubbish in my nappy bin sometime This time ive got an XLarge wetbag for baby which i will too keep in the kitchen next to the washer x
