It depends on which refill you're using and your baby's age (newborns go through more nappies than older babies). According to Tommee Tippee, the manufacturer of our top ranked nappy bin, each refill cassette should last around three to four weeks. How do I choose a nappy bin? Air-seal™: The multi-layer film technology in the cassette provides effective odour-barrier, for a more fragrant home If you’re using reusable nappies, then somewhere to store the dirty ones until you have enough for a wash is essential. Have the Angelcare one. Been amazing for the last six months. Would definitely get one again if I have another baby.” (Tried and tested by Mumsnet user Holliej) Our verdict

Can a nappy bin really be stylish? Well, yes, actually. The Ubbi Nappy Disposal Bin isn’t a cheap option, but it’s won several design awards and comes in several different colours – including Sage Green, Blush Pink, Chrome, Marble, Woodgrain and Slate – so there’s sure to be something to match your home decor. Long-Lasting - A single cassette lasts on average up to 1 month. Please note that all babies are unique and experiences may differ.

Nappy bins can range in size but, rather than focusing on the litre capacity, it's more useful to look at how many nappies each bin holds so you can judge the functionality better and will be able to estimate how often you’ll need to empty it. While the Ubbi Nappy Disposal Bin holds up to 50 nappies, most of the bins in our round-up will hold around 20 to 30 nappies.

Less Plastic - Because nappies are not wrapped individually, our system uses up to 4 times less plastic than similar products. Nappy bins for disposable nappies are designed to store used nappies until you have enough for a wash. Most state the number of nappies they hold, but this usually refers to size 1 nappies – the newborn size – which means that, as your baby grows, your nappy bin will hold less. When compiling our lists of recommendations, our team of experienced parenting journalists spend hours analysing every single product category, using a variety of independent sources to evaluate products against each other and assess which ones perform best. We then consolidated these results with the opinions of our huge network of Mumsnet forum users, which is the biggest online network of parents in the UK. Why you should trust us Compatibility: All Angelcare cassettes are suitable for all Angelcare Nappy Disposal Systems and help to provide a convenient and hygienic way of disposing of dirty nappiesOnce your baby is eating more, instead of fairly inoffensive milky poos (whether breast- or bottle-fed), you might find the need to get the nappy out of the house ASAP. There will also be far fewer nappy changes by then too – from 12-plus when they are a newborn, down to around six a day. How long does a nappy bin refill last? I use the Bambino Mio wet bags. Pricey but leak-proof and washable.” (Tried and tested by Mumsnet user FluffySavage) Our verdict Nappy bins are designed to keep smells contained but they will emit an odour when you open them for emptying. How often you empty a nappy bin is a personal choice, of course, and you may opt to empty it on a daily basis. Some nappy bins can fit a large volume of nappies, such as the Ubbi Nappy Disposal Bin which has capacity for up to 50 nappies. Sometimes, it’s good to think outside the box and just because you’re looking for a bin for nappies, that doesn’t mean you actually need a nappy bin. This 12-litre stainless steel pedal bin isn’t actually designed specifically for nappies but it’s a great value option, which will hold up to 25 nappies at any given time. Mumsnet users love the pedal on the Tramontina 12L Stainless Steel Pedal Bin as you can open it hands-free - useful if you’re also holding your baby.

Some users recommend zipped bags that you can put straight into the washing machine, rather than a nappy bin. They particularly like ones with a hook. We just use a normal lidded bin. Yes it smells when you open the lid to put a nappy in, but that only lasts a few minutes and TBH the room smells when a toddler has just pooed in it, regardless of how the nappy is disposed of." (Recommended by Mumsnet user BertieBotts) Our verdict Environmental impact: Plastic nappy bins and refill bags have an environmental impact so, if this concerns you, you may prefer to use more eco-friendly reusable nappies and a washable wet bag. Environmentally Friendly: As not all nappies are wrapped individually, the Angelcare Nappy Disposal System uses up to 4 times less plastic than other systems Lots of Mumsnet users stop using nappy bins after their babies start reliably eating solids. Weaning usually begins at six months, so you may find that your nappy bin becomes less useful when your baby is anywhere between eight and 14 months.

How we chose our recommendations

Granted, the initial outlay is a bit more than the cost of some of the other nappy bins we recommend, such as the Angelcare Nappy Disposal System (below). However, you don’t need to buy pricey replacement refills - you can just use standard bin bags. It’s made from sturdy stainless steel which makes it great at stopping whiffy odours from escaping - although it won’t be as efficient at odour zapping when compared to a specialist nappy bin such as the Angelcare. Another point to consider is that this bin will last you longer than a traditional nappy bin. When it’s finished its stint as a nappy bin, you can repurpose it as a stylish kitchen bin. Up to 28 Days Use: A single cassette lasts on average up to 28 days!
