13 Best Swim Diapers for Babies

13 Best Swim Diapers for Babies

Do you want to enjoy the beautiful pool water on a hot summer’s day but have a toddler in diapers with you? Don’t let that hold you back! The options for the best swim diaper for babies, both disposable and reusable toddler ones, are specifically designed to help prevent poop from leaking out into the pool. Since swimming pools are a distraction for kids, they could reduce your tot’s ability to perceive their body signals for when it’s time to go to the bathroom. What’s more, immersing them in water could also increase their need to dull and void all physiological indicators. Hence, a swim diaper prevents accidents from becoming a hassle, even if they can’t altogether avoid a bladder accident. But, they can delay it long enough for parents to figure out the situation.

Just like overnight cloth diapers are essential, so are swim diapers, especially for pool-loving families. Whether you’re looking for reusable or disposable, swim diapers are a blessing. To that end, here are the 13 best swim diapers, both disposable and reusable, for babies and toddlers.

How To Choose The Best Swim Diapers for Babies


Basically, there are two kinds of swim diapers, disposable swim diapers and reusable ones for babies and toddlers.

  • Disposable swim diapers are usually easier to put on and more affordable. But, they’re less mess-resistant than reusable pool diapers. If you rarely go swimming, this is a good choice for your family as you don’t have to keep washing it all the time.
  • Reusable swim diapers: For families who go into pools often. These diapers are more durable and value-for-money. What’s more, they’re very easy to clean, which means that non-soiled ones can be tossed in the laundry with the rest of the clothes. Plus, they’re more eco-friendly than their disposable counterparts but require cleaning every time.


The basic function of a swim diaper is that it should withstand water while containing solids. Since swim diapers aren’t necessarily designed to contain liquid but rather waste, anything else is a bonus. So, parents need to think of the features that are most important to them. Whether you want full protection or want snaps on the sides for easy pulling on and off, ensure the functionality.


Fit is one of the most important factors when it comes to finding a swim diaper, as it involves a fair bit of trial and error. Swim diapers need to fit more snugly than their regular counterparts for them to be able to do their jobs properly. So, check your child’s weight and regular diaper size for guidance. What’s more, features such as the adjustable snaps or a waistband might mean that a diaper can fit between sizes or as your toddler grows. Finally, some diapers even have adjustable drawstrings to ensure that kids get a snug fit.

Should the baby wear a diaper while swimming?

No, regular diapers absorb liquids and can’t be worn swimming, even if you make your babies wear them beneath swim diapers. That’s because they quickly become waterlogged when submerged, thus also becoming very weighty.

Do swim diapers keep the poop in?

Despite swim pants and diapers being able to hold in some solid feces, they aren’t leakproof!

Do babies wear diapers under swim diapers?

No, they don’t But once your baby is out of the pool, change them into regular diapers.
