Glistening lakes, the seashore and cool pools beckon to kids and their parents on hot summer days. Don’t let having a little one in diapers hold you back from getting in the water.

Do You Need Swim Diapers?

If your child isn’t potty trained and they want to dip toes (and more) into a public body of water, you need swim diapers. Regular diapers won’t work. The material that makes diapers so absorbent also turns them into a waterlogged anchor around your child’s waist once they are submerged in water. Not only is their absorbing action rendered useless once they soak up water, but their weight makes them super saggy to the point of falling off. And they definitely can’t hold anything inside once they’re stretched out.

Swim diapers are designed to withstand water and contain solids. They aren’t meant to absorb. Yep, that means pee will pass through to the water. But swim diapers should keep number twos inside, eliminating what public pools fear most: fecal contamination. (Everyone out of the pool, closed for days or weeks as it’s drained and refilled, etc.)

You may be thinking, “What about when my child is out of the water?” Because there is no absorbency, you’ll have to change your baby into a regular diaper right after swimming. For some reusables you can purchase absorbent inserts for the diaper while they toddle around on land.

Note: Swim diapers aren’t designed for newborns whose stools tend to be liquidy (until they start eating solid food). Lacking absorption power, they just can’t contain newborn poops. The same goes for children with diarrhea. They should not be allowed to swim in a public body of water.

If you want to introduce your baby to water before two months of age, try filling up the tub at home or using a kiddie pool rather than heading to the community pool.

What Type of Swim Diaper is Best?

Remember that swim diapers need to have a snug fit to contain poop, so they will probably be tighter than your everyday diapers.

Swim diapers come in disposable or reusable versions, each with their own advantages. Disposables are cheap and offer convenience, but they tend to sag and are more prone to letting something slip out.

Reusable swim diapers that have Velcro or snaps at the side usually offer a better fit, but are more expensive and high maintenance. After changing your child out of a reusable, you have to flush the diaper contents down the toilet, package the dirty reusable to take home, and then rinse it and run it through the wash. Also, since babies grow pretty quickly, they might grow into a larger reusable size before the summer is over. Consider how quickly your little one is growing before investing in a reusable swim diaper.

How Does this Work at the Pool?

If public pools allow diapered children to enter at all, their rules may differ. Many require kids to have two layers. A disposable diaper along with a reusable or a swim short on top can work, or some allow a reuseable underneath with a swim short on top. Many parents find that disposable on bottom and reusable on top is the best defense against spillage anyway.

Cuteness Factor

Why We Love It

These reusable swim diapers come in a bunch of cute patterns and have a light absorbency (i.e. will catch a tiny bit of urine outside the pool). The bonus? They are less expensive than other reusables.

Keep in Mind

Be sure to buy the version that has snaps at the side. If you accidentally purchase the pull-up style, you’ll be sorry. Dragging a poopy diaper down your baby’s legs and feet makes a huge mess. Also, this brand runs really small, so size up.


Why We Love It

Low cost and featuring tear-off sides for removal, these disposables are a great, no-hassle option.

Keep in Mind

Getting these disposable swim diapers on isn’t as easy as getting them off. The pull-up style can be frustrating as it sticks to sweaty, sandy kids.

Sun-Sensor Design

Why We Love It

These disposables are major multi-taskers with UPF 50 protection and color-changing technology. After both initial and prolonged exposure to UV rays, the diaper’s design will fill with color and scenery, indicating it’s time to reapply sunscreen and check your baby’s diaper for poop.

Keep in Mind

Like other disposables, Babyganics has a pull-up style that can make putting a fresh one on a wet, wriggling baby or toddler a pain.

Long-Lasting Comfort

Why We Love It

This reusable option has plenty of features we appreciate: a concealed water-resistant layer, leak-proof leg cuffs, soft cotton terry lining and a comfy drawstring waistband.

Keep in Mind

Since the fit is adjusted via a drawstring at the waist rather than with snaps, be sure to stretch the waistband as loose as it’ll go before pulling it down your baby’s legs so you lessen the mess.

Bold and Bright

Why We Love It

We love Primary’s clothes and swimwear for their basic-but-colorful designs, and these swim diapers are no exception. Made with an outer layer of nylon and elastane, and a concealed water-resistant lining that contains the mess without swelling, these also have a snug fit around waist and legs. They also have UPF 50.

Keep in Mind

These swim diapers don’t have snaps, so you’ll have to pull them off.

Personalized Fit

Why We Love It

Two words: adjustable sides. These reusable swim diapers have snap closures at varying levels for three different fits in one, and you can easily readjust them to fit a growing baby or size them down for a new addition. Soft mesh inside and a trim fit means they’re super comfortable for your little one and they hold all the messy stuff in.

Keep in Mind

Some parents say these diapers run small, so you may find yourself using the next level of snaps before you intended. Also, they don’t provide as customizable of a fit as swim diapers with Velcro.

Choosing what’s right for you

Since many families use both disposable and reusable swim diapers together, you might want to purchase both and see how it goes. You may find the twofer system works great or that one or the other causes chafing or slides right off your baby’s bum. Finding the perfect swim diaper for your little one will be worth it for all the splashing, smiling fun this summer.
