Swimming with a diaper doesn’t have to be a messy and confusing affair!

Children as young as three months old can be in the pool, but this can be particularly difficult when your little one is still in diapers. Many parents are confused or uncomfortable with the idea of dealing with wet and dirty diapers, but that doesn’t have to be the case. Here is AquaMobile’s guide to help you find the best swim diaper for a happy swimming session!


Generally, all swim diapers are meant to hold solids in and allow liquids to escape. It is recommended – even required in several states – for swimmers to wear plastic pants over any type of swim diapers (reusable or disposable) for extra security.

The Importance of Swim Diapers

  • Regular diapers will absorb water and weigh your baby down
  • All public pools and most beaches require swim diapers
  • Pool cleanups after “number two” accidents are expensive and result in the pool being closed for many hours
You can find swim diapers in reusable or disposable form in today’s market.

Reusable Swim Diapers

While most reusable swim diapers are typically lined with a polyester mesh layer, some have built-in plastic (or swimsuit-material) pants over the diaper. A single reusable swim diaper costs between $7-$20 and most come in a variety of colours and patterns. They look like regular swimsuits, such as the i Play reusable swim diapers, which carry budget-friendly lines. If necessary, you can use a flushable liner (such as the Bumkins Flushable diaper liners) inside the diaper for easier cleanup. It is the most economic option for frequent swimmers.
There are two main types of reusable swim diapers:

  • Velcro Straps: Easily adjustable to your child’s body, but tend to snag on other clothing in the washing machine.
  • Snap Closure: These swim diapers may not be as adjustable as the ones with velcro straps, but they are just as easy to put on and take off of your little one.
  • Pull on: Using this type of swim diaper is a simple pull on/pull off process, but be aware that it might be difficult to take off of a child without spilling the contents.

A popular reusable swim diaper brand is the Swimmi by Bummis (~$16). It features velcro straps, which allow for maximum flexibility when it comes to your toddler’s waist. This is important as swim diapers work best when they fit as snug as possible. The smallest size for the diaper starts at 9 pounds, so even most infants are able to use it.

Swim Diaper Tip #1

Buy at least two reusable swim diapers, so that your child can quickly change in and out of dirty diapers for an uninterrupted swimming session.

Swim Diaper Tip #2

Some pools have policies against rinsing reusable swim diapers in their washrooms. Bring a plastic bag to keep dirty swim diapers in just in case.

Disposable Swim Diapers

Similar to regular diapers, disposable swim diapers are thrown away after use. However, they do not swell up or weigh your baby down when exposed to water. The aesthetics are generally not as pleasing as their reusable counterparts, as the patterns fade and wrinkle after each use, but some parents prefer the convenience. Two of the most popular disposable swim diaper brands are the Huggies® Little Swimmer® and the Pamper Splashers. Their prices ranges from 40¢ -60¢ per diaper depending on the size, and are generally sold in packs of 20 . Some parents prefer one to the other, while others advocate to buy whichever is cheaper because both are virtually the same. To find the perfect fit for your little one, we recommend navigating disposable swim diapers by trial and error.

Swim Diaper Tip #3

When on holiday, bring at least 3 disposable swim diapers for each day you plan to swim with your child, and bring 3 additional ones as backup.
