The Ultimate Guide to Reusable Swim Nappies
, by Hello Charlie Blogs, 3 min reading time
If your baby or toddler is not toilet trained, they need a swim nappy for the pool or beach.
But regular nappies and swim nappies are not the same thing.
A regular disposable nappy is designed to absorb liquid. Put it in water and it will swell, become heavy and stop working properly. A swim nappy is designed to let water pass through while helping contain solids.
Reusable swim nappies are a practical low-waste option for babies and toddlers who love the water.
What is a reusable swim nappy?
A reusable swim nappy is a washable nappy designed for swimming.
Unlike a normal nappy, it is not designed to absorb wee. Instead, it is made to contain poo while your baby is in the water.
After swimming, you wash it and use it again.

Why choose reusable instead of disposable swim nappies?
Reusable swim nappies can be a better option if your family swims regularly.
They can help:
- Reduce single-use waste
- Save money over repeated swims
- Provide a comfortable fit
- Avoid carrying extra disposables
- Make swim lessons easier to prepare for
If you only swim occasionally, disposable swim nappies may still be convenient. But for regular pool visits, a reusable swim nappy is worth considering.
How should a swim nappy fit?
Fit is very important.
A swim nappy should be snug around the waist and legs, but not so tight that it leaves deep marks or restricts movement.
Check:
- No gaps around the thighs
- Waistband sits comfortably
- Baby can kick and move easily
- The nappy stays in place when wet
- It is easy enough to remove after swimming
If your swim nappy is too loose, it may not contain mess properly.
Do swim nappies hold wee?
No, not in the way regular nappies do.
Swim nappies are not designed to absorb urine. If they did, they would also absorb pool water and become heavy.
Put the swim nappy on just before swimming, and change your baby into a regular nappy when they get out of the water.
What if your baby poos in the pool?
Remove your child from the water straight away.
Follow the pool or swim school’s hygiene rules. Remove the swim nappy carefully, clean your child, and place the dirty swim nappy in a wet bag until it can be washed.
Always pack a spare swim nappy if you will be swimming for longer than a short session.
