Swim diapers are vital for days at the pool and beach if your child isn’t potty trained. Swim diapers enable you and your child to enjoy accident-free swimming as regular diapers are ineffective due to their high absorbency. The basic construction of these bags includes a waterproof outer layer and a solid waste-containment inner lining.
Swim diapers are available in both disposable and reusable options, but the choice ultimately depends on your preference. While disposable diapers are more convenient for clean-up, reusable swim diapers are more environmentally friendly. Read on to discover the best swim diaper for your child’s next water adventure.

- Adorable design/pattern
- Adjustable, so it could grow with your baby

These adjustable swim diapers are a game changer because you only need one swim diaper instead of 4-6 different sizes, which saves you time and money. Unlike pull-up type swim diapers, these reusable swim diapers are easy to take off and don’t leave a mess.
The PUL outer layer cloth of the swim diaper contains any accidents, so you don’t have to worry about embarrassing leaks in the pool. The interior layer of polyester mesh is not only comfortable but also keeps your baby’s skin hygienic.
This doesn’t have an inner layer because it would absorb water while swimming and make your baby’s bottom sag. You won’t have to worry about diaper rash with these swim diapers because excess water won’t sit on your baby’s skin, unlike other swim diapers that have stiff elastic or scratchy fabric.

How To Choose The Best Baby Swim Diaper?
- Type: Ask yourself if you prefer disposable or reusable swim diapers. Reusable diapers cost more upfront, but you’ll save money in the long term.
- Fit: For a snug and secure fit, be sure to select a swim diaper that is the proper size for your infant. They should fit a little tighter than a typical diaper.
- Adjustability: Reusable diapers often offer a better value overall since they can be adjusted frequently, and you might be able to use the same diaper until your child is toilet trained.
- Purpose: Consider how frequently you’ll use the swim diaper. You might not require the thickest swim diaper available if you only visit the beach or pool a few times a year. On the other side, you’ll need a swim diaper that can withstand heavy use if you live near the beach or have a pool in your backyard.
What Are The Different Types Of Swim Diapers?
There are three main types of swim diapers:
- Disposable Swim Diapers: These are made from a waterproof material, with an absorbent liner in the middle. They are easy to use and don’t require any special washing.
- Reusable Swim Diapers: These are made from a waterproof material, with an absorbent liner in the middle. They can be washed and reused multiple times.
- Hybrid Swim Diapers: These are a combination of disposable and reusable diapers. They have a waterproof outer layer, with a reusable absorbent liner in the middle.
What Is The Smallest Size Of Swim Diapers?
The smallest size of swim diapers is for infants 0-3 months. These diapers are designed to fit babies who are between 8-14 pounds.
Do Swim Diapers Hold Newborn Poop?
Despite the fact that the majority of swim diapers are made to hold solid waste, some parents claim that their children’s poop has occasionally spilled out of swim diapers (1). This is due to the fact that swim diapers aren’t made for newborns whose stools frequently include liquid. You might want to think about using a disposable swim diaper liner if you are worried that your baby’s poop will leak out of their swim diaper.
Nevertheless, pools often have requirements for swim diapers as they play a crucial role in minimizing the spread of parasites and bacteria that can cause infections and diseases like diarrhea. Swim diapers act as a barrier between your child’s waste and the pool water, preventing the spread of harmful pathogens like Cryptosporidium.
How Often Should You Change The Swim Diaper?
Swim diapers should be checked every 60 minutes, according to the CDC (1). There are a few other considerations to take into account, though. If your child has had a bowel movement, you must first immediately change the diaper. The diaper should probably be changed if your child has been in the water for a long time and it is beginning to appear full. Plus, the diaper should be replaced if there are any leaks or other indications that it is no longer functioning properly.
Do You Put A Regular Diaper Under A Swim Diaper?
No, you don’t need to put a regular cloth or disposable diaper under a swim diaper. Swim diapers are designed to be worn alone and don’t require an additional diaper underneath.
