The first question you should ask yourself when buying a rubbish bin, is how big must it be. Do you have a large family or do you live on your own? That will make a huge difference in the amount of waste your household produces, and the garbage bin you need. You might be thinking: the bigger, the better. But if it's just the two of you, a huge bin won't be such a good idea. If the bag isn't replaced regularly because it isn't full yet, you will soon be faced with bad smells. And a family with four children will soon regret buying a rubbish bin with just a 30 liter volume. So choose a model that suits your household.
