How to Keep a Cast Dry in a Swimming Pool or Bath

This site generates income via purchases made through links to carefully-curated travel and lifestyle brands.

The bummer about breaking a bone in the summer is that standard casts are usually not waterproof.

I do not know the circumstances that make you eligible for a waterproof cast. I asked for one and they looked at me like I was crazy.

We had three mini-vacations scheduled the month following the break that all involved swimming pools and beaches. I wasn’t sure what to do.

I ultimately bought a cast protector for swimming and baths.

The Waterproof Cast Cover I Bought

After some research, I bought a DryPro Waterproof Cast Cover, because, at the time, it was the only one I could find with an allowance for swimming.

Until it arrived, I was pulling my hair out using the unreliable multiple plastic bags and rubber band methods in the shower.

The Dry Corp waterproof cast cover is basically a giant rubber blue arm that suctions tightly to the skin several inches or so above the end of the cast.

You put the cast cover on the arm (it takes a bit of effort) and suction the air out with a little balloon via a small white valve.

This waterproof cast cover is tight so you are not supposed to wear it for more than 45 minutes at a time.

I would even say less is better. My daughter never complained about this waterproof cast protector, probably because she knew there was no swimming without it.

Does This Cast Cover Work?

On Dry Corp’s website, there are children wearing the cast cover on the beach. I did not allow my daughter on the beach with it. There are too many ways that sand can creep into the cast cover and, therefore, down into her cast. 

The only solution I could think of was to put it on before we got to the beach and leave it on until we returned to our hotel room and she bathed completely.

All-in, that left about 10 minutes or so for us to actually be at the beach. In our case, this wasn’t worth it.

Also, if my daughter played with pool toys like kickboards or inner tubes, the top of the waterproof cast cover rolled down and let water seep in. On occasion, I also found water seeping in through the valve where you suction the air out.

There was never enough water to damage the cast, but it was moist and is something to look out for.

In our experience, the cast cover wasn’t totally waterproof, but it was enough to get by and not let a broken bone ruin vacation plans.

If your child can be careful while swimming with a cast, this may be a solution for you. It definitely helped us bathe and I’m just not sure what I would have done without it.

For us, it was worth the money.

The also make waterproof cast covers in adult sizes. And if you live in San Diego, read my post about breaking a bone after hours.

  1. Can you tell me what you did for her while you were at the actual beach? Was she able to play by the sand at all?

    1. I would wear it if you have to be at the beach for a short amount of time but would not actively play in the sand. Sand could get caught in the top of the sleeve and it might be hard to control it when you roll the sleeve off.
