How to Shower With a Cast Without Getting It Wet
A cast or dressing has to stay dry, but recovery lasts weeks. A waterproof cast cover makes normal showering possible from day one — this guide explains how the covers work, how to fit them correctly and when a reusable cover makes more sense than a disposable sleeve.

Why keeping a cast dry matters
The padding under a cast holds water for a long time. Damp padding against the skin causes itching, maceration and odour, and can lead to skin breakdown or infection around a healing fracture or surgical site. Plaster casts can also soften and lose the shape that supports the bone. Improvised solutions — bin bags, cling film and tape — leak at the wrist, ankle and knee because they have no elastic seal.
Step by step: showering with a waterproof cover
- 1
Check the cast and skin first
Before every shower, look for cracks in the cast, damp padding or irritated skin at the edges. Never cover a cast that is already wet inside — dry it and let a clinician check it.
- 2
Choose the right cover size
Waterproof covers are sized by limb and length: short arm, long arm, short leg, long leg, plus dedicated paediatric sizes. The seal must sit on healthy skin above the cast, not on the cast itself.
- 3
Roll the seal into place
Open the seal with both hands, slide the cover over the cast without stretching the ring, then let the seal settle flat against the skin. Smooth out folds — folds, not water pressure, are what usually cause leaks.
- 4
Shower, don't submerge
A waterproof cover is designed for showering, bathing and washing. Keep the limb out of deep, prolonged submersion unless the product explicitly allows it.
- 5
Remove and dry
Peel the seal off slowly, rinse the cover with clean water, shake it out and hang it to dry inside out. A reusable cover that is dried properly stays usable for the whole recovery period.
Reusable vs. disposable cast covers
| Criterion | Reusable cover | Disposable sleeve |
|---|---|---|
| Cost over 6 weeks | One cover covers the whole period | A new sleeve per shower |
| Seal quality | Elastic seal, consistent fit | Thin film, adhesive-dependent |
| Waste | Minimal | High |
| Best for | Home recovery, daily showering | Single clinical use |
Frequently asked questions
Can I shower with a cast on?
Yes, provided the cast stays completely dry. A correctly fitted waterproof cast cover seals against the skin above the cast and lets you shower normally. Plastic bags and tape are not reliable and often leak.
What happens if a plaster cast gets wet?
Wet padding stays damp against the skin, which can cause itching, skin breakdown, odour and infection, and a soaked plaster cast can lose its shape and stop supporting the fracture. If a cast gets wet inside, contact your clinician.
Are reusable waterproof cast covers better than disposable ones?
Reusable covers are more economical over a typical 4–8 week recovery, produce far less waste and offer a stronger, more consistent seal. Disposable sleeves suit short-term or single-use clinical situations.
Can children use waterproof cast covers?
Yes. Paediatric sizes exist for short and long arm and leg casts. AKLION Kids Waterline covers use the same waterproof seal with playful outer prints so children accept them more easily.
Can waterproof covers be used over dressings and wounds?
Yes — the same covers protect dressings, bandages, post-operative wounds and PICC lines from water during showering, as long as the seal sits on intact skin.
Find the right waterproof cover
AKLION Waterline covers are available for short and long arm and leg casts, for adults and children, in retail boxes, resealable pouches and bulk cartons.
