If you are a parent of an infant or a toddler, you are possibly worried about taking your child to a public pool or a beach because they are not potty-trained yet. Luckily, there is a solution to this problem – swim diapers. These are designed for your child to wear while in water, and they are not the same as regular diapers.

The purpose of swim diapers is to keep solids in, this way preventing contamination of the pool and ensuring that both you and everyone else are going to have a nice day. You have a choice between two types of swim diapers – reusable and disposable.

Both are efficient against poop and unpleasant accidents, but will not contain urine. However, not all products are the same, so you need to inform yourself a bit more in order to find a swim diaper for your child. Take a peek at fantastic products we selected for you, and don’t miss out on the buying guide below to learn about particular features you should look for in a pool diaper.

Let’s get started.

How To Choose A Swim Diaper – Buying Guide


In order for a swimming diaper to work, it must fit your child properly. Other things become insignificant if the diaper makes your child uncomfortable, or if it’s too large and can’t contain anything. This is the first thing you need to pay attention to. Take a look at other important features and buy one of the best swim diapers for your child.


A swimming diaper is not the same as a regular everyday diaper. It does not swell when exposed to water and it usually has a nice print or pattern on it to make it more interesting to your child. Depending on the type you get (reusable or disposable), they can have Velcro straps, snap buttons, or simply be pulled on/off type. Which style is best for you depends on how often you go to the pool and whether you prefer convenience or durability.

Reusable vs. Disposable

If you go to the pool often, you should invest in a few reusable diapers. Even though these are initially more expensive, they are going to pay off in the long run, since you can use them many times, especially if you have a swimming pool at home. On the other hand, if you are only going to go swimming several times during the season, then buying a pack of disposable diapers is a better idea, money-wise.

Whichever type you choose, you are going to need several diapers to cover a whole day at the pool. Keep in mind that neither type is absorbent and meant to keep in liquids, so don’t put them on your child in advance or you risk having urine everywhere.


Reusable pool diapers are usually made from either polyester or cloth and have a mesh lining inside. They can be washed in a machine and used many times over. However, it’s a little inconvenient having to take a dirty diaper home with you. But think about this – a reusable swimming diaper is more eco-friendly since you don’t throw it away after each use. They come in many colorful designs to choose from and look really nice on your kid.

Many manufacturers make these to be adjustable – they either have snaps or Velcro tape included, so you can properly adjust them to fit. The upside of this is that your child can use them for a longer time period, saving you the expense of buying a new pair. Always consider that your child is going to grow when you choose reusable diapers.


Disposable pool diapers are more convenient to use. You put them on your child as you would a regular diaper. They usually come with tear-away sides and allow you to easily pack them and toss them in the trash. You have almost no cleaning to do afterward. Of course, you can’t wash these and use them again. So, if you plan on taking your child to the pool every day, disposable diapers can become quite expensive.

This type of baby diapers can either be similar to regular diapers or reusable ones. It is sometimes made from plastic or paper with an absorbent crystal inside, or it can be made from non-absorbent fabric (much like reusable ones). Pay attention that the diapers you choose won’t become heavy when wet because your child is going to want to take them off. In the worst-case scenario, they can slip right off and beat the purpose of having a swimming diaper in the first place.

Size and Age

Swimming diapers are made for children who are not yet potty-trained. This ranges from 3-month-old infants up to children who are 4 years old (if they happen to need it). There is a large selection of sizes in our reviews so you can certainly find the right product for your child. Always read the product information carefully, because some children are larger than others, and the fit is not universal. Also, as we mentioned, reusable diapers can be adjustable thanks to their design, so they can be used for a longer period.


It is important that the diapers are convenient to use. You should be able to quickly put them on your child and take them off, and the diaper should remain in place while your child is in the water. You can use a swimming diaper either on its own, or wear a swimsuit on top of it. If you want to put it underneath a regular swimming suit, make sure that the diaper is thin, to avoid it being bulky and heavy.



Q: Why buy swim diapers?


Because they are specifically designed to contain poop and prevent contamination of the swimming area. This way you save yourself from an awkward situation, and others from potentially dangerous infection. E.coli can be found in feces and can put other people in danger if it spreads.

There are strict procedures if fecal matters end up in a swimming pool – it needs to be closed for cleaning. Always check with your swimming pool what is allowed at their facility. Some allow children in swimming diapers, others will require that your child has a swimsuit on top of the diaper, while some won’t allow children who are not potty-trained.

Q: Does my child need swim diapers?


Yes, your child needs special swimming diapers, because regular diapers simply won’t perform well when exposed to water. Regular diapers have crystals inside which are meant to absorb water, so they will quickly fill up and become heavy and inefficient. This is why you need pool diapers – to be certain they will be effective while you are in the water with your child.

Q: How do swim diapers work at the pool?


They work by containing solids inside the diaper. Like we mentioned, they won’t contain urine very well. Your child will have the best protection against leaking if you combine a disposable diaper underneath with a reusable diaper on top. It’s certainly a good idea to take your child to the toilet often, so you can avoid dealing with diaper change at the swimming pool.

If you use a reusable diaper, check it from time to time to see if it’s soiled. If it’s full, empty the contents down the toilet, pack it and take it home. It’s a good idea to have a plastic bag in which you’re going to put it, for easier handling. You should rinse it when you come home, and then put it in a washing machine.

If you choose disposable diapers, everything is much simpler. You just take it off, pack it and dispose of it. In both situations, if you notice that your child has soiled themselves, replace the diaper away from the swimming area. Also, be sure to always have a few backups at hand.

Finally, if your child is still on a liquid diet, it will have a runny stool. Swimming diapers aren’t able to contain any liquids very well, so it’s smart to wait some more before going to the pool in this situation. The same thing applies if your child has diarrhea on the day you go to the pool. If that’s the case, it should avoid swimming because diapers won’t be very effective.
