Do Swim Diapers Actually Work?

Do Swim Diapers Actually Work?

According to the Centers for Disease Control and Prevention (CDC), swim diapers are meant to keep solid feces contained but are not 100% leakproof.

Swim diapers CANNOT prevent pee, diarrhea, or infectious germs from contaminating the water.

They can only delay poop from leaking into the water for a few minutes.

That being said, most public pools REQUIRE swim diapers for babies because they prevent the leakage of infectious germs to an extent.

Although swim diapers are effective, it’s still recommended to take frequent bathroom breaks and diaper changes.

IMPORTANT: Babies with diarrhea should NOT get into the water due to the risk of contamination to other pool users.

Parents and caregivers should check their baby’s swim diaper every 60 minutes to ensure they don’t make a mess.

Change swim diapers as often as needed and in the designated diaper-changing area.

How to Choose the Best Swim Diapers

How to Choose the Best Swim Diapers

The best swim diaper for your baby should have a secure fit and can contain their poop.

Aside from that, there are other factors you need to consider. Check out everything you need to look for when choosing baby swim diapers:


The best swim diapers are those that are certified safe and organic by official organizations.

Certain certifications like Oeko-Tex are proof that the diapers have been tested for harmful chemicals and are made of safe, natural materials.

In my opinion, it’s hard to disprove certifications, and it makes it easier to trust the brand I’m buying from.

It shows they are transparent and reliable and put a lot of importance on the safety of their products.


In relation to the materials, look for swim diapers made from baby-safe, skin-friendly materials.

My go-to materials to look for are organic cotton or wool. Any baby clothes for that matter made from these materials is the way to go!

Organic cotton is soft and easy on the baby’s sensitive skin, so they will not experience any irritation while in the water.

Avoid any harsh materials that may cause skin irritation or allergic reactions.


When looking for a swim diaper, you’d want one that can fit your baby’s bum AND is delicate enough for their skin.

Unlike regular diapers, swim diapers need to be secure, but that doesn’t mean they should be a tight squeeze for your tot!

It may take a bit of trial and error to find the right one for your baby, though.

Know your baby’s size so you can find the right diaper. Check the size charts or product details before you purchase.

Don’t worry if it’s tighter than their regular diapers! Pool diapers are meant to be extra secure to keep any messes from leaking.


Most swim diapers are designed to be easily adjustable.

Disposable diapers also come with adjustable tabs, like regular ones, which you can readily configure to ensure a snug fit for your baby.

On the other hand, there are also swim diapers that are pull-on rather than adjustable.

Reusable swim diapers typically have velcro straps that you can adjust accordingly.

Adjustability is a major factor to consider if you’re looking for a swim diaper with your baby as they grow.


Reusable swim diapers are pricier than your average but worth the investment.

They are more cost-effective and space-saving than disposable ones, especially during vacations or swim lessons.

You can wash and use them repeatedly instead of buying new packs.

The best reusable swim diapers are also more leakproof than their disposable counterparts. They can last for years if maintained properly.

Unlike disposable diapers made of plastic, the reusable swim can be difficult to clean when your child poops.

Waterproof Outer Layer

A waterproof outer layer is essential for preventing leaks and blowouts while in the water.

With this layer, you can keep any leaks or poop contained in the diaper without having it bother the baby.

Having this barrier can keep the baby happy despite having a loaded diaper and it also keeps other swimmers safe from the baby’s messes.

Stylish Design

Design is just a matter of preference, but it helps to have a design that catches the baby’s attention so they will be more enticed to wear it.

I like going all out in terms of design as it gets my baby excited to wear them, so it helps to be particular about design as well.

It doesn’t have to be your top priority, though.


Swim diapers come at various price points.

You can opt for disposable swim diapers, which are generally affordable if you don’t go to the swimming pool often.

Aside from being inexpensive, they are also more convenient.

Reusable diapers cost more upfront but are more cost-effective in the long term. It’s a single-purchase investment that can be washed and used repeatedly.

Depending on how often your baby will go in the water, you can save more with a reusable swim diaper than with disposables.

Does My Baby Need Swim Diapers?

Does My Baby Need Swim Diapers?

If your tot is NOT potty trained, they must wear swim diapers. It will help contain any bowel movement before it can get into the water.

Swim diapers work by providing extra protection around your baby’s legs and waist to prevent leaks.

Not only does it reduce the chances of poop contaminating the pool, but it also prevents any embarrassing accidents from happening.

Do note that swim diapers are not completely leakproof. They can only hold solids, not liquids.

If your baby pees, it will pass through the diaper. That’s why checking your baby’s swim diaper periodically while in the pool is essential.

Reusable Swim Diapers vs. Disposable Swim Diapers

Reusable Swim Diapers vs. Disposable Swim Diapers

There are two main types of swim diapers: disposable and reusable swim diapers. You can choose which type is the best for your baby depending on your family’s lifestyle:

Reusable Swim Diapers

Reusable diapers are made with waterproof, multi-layered fabric intended to be washed and re-worn.

These diapers are built to be durable enough for PROLONGED, long-term use.

After you’ve discarded the solids, you can easily toss the reusable diaper in the laundry. You can reuse them over and over without having to buy new ones every time.

A reusable swim diaper comes at a higher initial cost than a disposable swim diaper but can save you a lot in the long run.

Their reusability makes them far more cost-effective and eco-friendly!

EXTRA TIP: The best diapers for babies are those made of non-toxic materials. Keep them safe and comfortable with any of these non-toxic diapers.

Disposable Swim Diapers

Disposable diapers are used only ONCE and thrown away after use.

They are a good choice if your family doesn’t go swimming often OR if you’re going on vacation where you can’t wash a diaper every time you get in the pool.

They are generally more affordable than reusable ones.

However, the costs can add up compared to a one-time purchase like a reusable swim diaper. Disposable ones can work well enough unless you take your tot to swimming lessons.

Can Regular Diapers Be Used for Swimming?

Can Regular Diapers Be Used for Swimming?

No, a regular diaper will not cut it.

Regular cloth diapers have an absorbent inner layer intended to absorb pee, including most liquids. When placed in the water, it will soak up everything.

They can become bloated with water and unable to absorb urine. Regular diapers can even break open, resulting in a big mess.

Using a regular diaper in the pool WILL NOT keep poop or pee from leaking into the water.

They are ineffective for swimming and can also be uncomfortable for your tot when filled with water.

Because of this, it is not advised to use regular diapers on young babies when swimming.

Frequently Asked Questions

Here are some commonly asked questions about swim diapers that you might be asking yourself.

How Do I Clean and Maintain Swim Diapers?

If you want your baby’s reusable diaper to last, you can keep it in good condition by doing the following:

  • Dispose of any waste in the diaper
  • Wash it with water
  • Run through a hot wash cycle with detergent
  • Rinse using hot water
  • Tumble dry

The exact washing instructions for swim diapers depend on the manufacturer’s specifications. Check the care guide to determine how to wash your reusable swim diaper.

Do You Have to Put a Diaper Under a Reusable Swim Diaper?

If you already have a reusable swim diaper, you don’t need a diaper. A swim diaper under a bathing suit should work well enough.

If the pool you’re going to requires a double layer of diapers, you can use a disposable swim diaper underneath.

Remember that you CANNOT use a regular diaper when swimming because it would absorb too much water.

How Many Swim Diapers Do I Need?

It would depend on how frequently you plan to get your baby in the water. I recommend bringing AT LEAST TWO swim diapers in your diaper bag per swimming experience.

If you’re going for disposables, you must pack enough for your trip since you’ll need to discard them more often.

With reusable diapers, you must consider washing and drying time. For week-long outings, you might want to have four diapers on hand.
