Showering with a broken leg is mostly a problem of keeping your cast or splint dry while not falling on a wet surface. The good news: with the right setup and about 10 minutes of prep, you can shower safely and comfortably at home. The key is a waterproof barrier for your leg, a secure place to sit, and everything within arm’s reach before the water turns on.
Waterproofing Your Cast or Splint
Your cast cannot get wet. Moisture trapped underneath leads to skin breakdown: the skin turns white and swollen, then progresses to redness, inflammation, and eventually creates a breeding ground for fungal infections. Once water gets inside a plaster cast, it’s extremely difficult to dry, and you may end up needing a replacement. So waterproofing is non-negotiable.
The most effective method is also the cheapest: a large plastic garbage bag sealed at the top with duct tape. A study published in the Journal of the Pediatric Orthopaedic Society of North America tested multiple commercial and DIY cast covers and found that a plastic bag with duct tape was the single best performer, absorbing only about 3 milliliters of water on average. Researchers rated it the only “excellent” option and recommended it as the gold standard because the tape creates a custom seal that conforms to any limb size.
If you’d rather buy a dedicated product, three commercial covers performed well in the same study: Bloccs, Seal-Tight, and DryPro. All three earned a “good” rating, though they cost around $30 each and their fit was more variable across different leg sizes. The seal at the top of the cover is what matters most for keeping water out, so if you go commercial, make sure the opening grips snugly against your skin above the cast.
Several popular options failed badly. A plastic bag secured with rubber bands leaked significantly. Press’n Seal plastic wrap and store-brand cast covers from Walgreens and Curad all allowed substantial water through. Skip these entirely.
How to Wrap Your Leg
Slide the garbage bag over your foot and up past the top edge of the cast by several inches. Smooth out any folds or air pockets. Then wrap duct tape firmly around the bag opening where it meets your bare skin, overlapping each strip so there are no gaps. The tape should be snug but not tight enough to cut off circulation. You’ll tear this off after each shower, so plan on using fresh materials every time.
Setting Up Your Shower
Trying to balance on one leg in a wet shower is a recipe for a second injury. A shower chair or stool placed inside the shower lets you sit while you wash, which is safer and far less exhausting. If you have a walk-in shower, a basic shower stool works well as long as you can step in and lower yourself onto it without needing to lean on it for support. Place a non-slip bath mat under the stool so it doesn’t slide on wet tile.
If you have a bathtub you need to climb over, a tub transfer bench is a better choice. This is a long seat with two legs inside the tub and two legs on the bathroom floor outside it. You sit down on the outside portion first, then slide yourself across and into the tub without ever having to lift your leg over the rim while standing. Transfer benches are widely available at pharmacies and medical supply stores and typically cost $40 to $80.
A detachable shower head on a flexible hose is almost essential. It lets you direct water exactly where you want it and, just as importantly, away from your broken leg. If you don’t already have one, most handheld shower heads screw onto your existing pipe in a few minutes with no tools.
Grab Bars: Suction vs. Permanent
You’ll want something solid to hold onto when getting in and out. Suction-cup grab bars are tempting because they install in seconds, but they are not designed to bear your full weight. Manufacturers explicitly warn against relying on them if you slip or lose balance. They’re rated for light balance assistance only, and soap scum, textured surfaces, or moisture creeping under the seal can cause them to pop off without warning. Multiple users on Mayo Clinic’s patient forums reported suction bars failing in actual use.
If you’ll be recovering for weeks or months, permanent grab bars screwed into wall studs are far more reliable. They won’t loosen over time and can fully support your weight in an emergency. A handyman or even a confident DIYer can install one in under an hour. If drilling into tile isn’t an option, a floor-to-ceiling tension pole with a grab handle is a middle-ground alternative, though it’s still less secure than a stud-mounted bar.
Before You Turn On the Water
Once you’re seated in the shower, getting up to grab something you forgot is difficult and risky. Gather everything beforehand and place it within arm’s reach of your shower seat:
- Shampoo, conditioner, soap, and washcloth on a caddy or shelf you can reach while seated
- Your cast cover already applied and sealed before you enter the bathroom
- A dry towel draped over the shower door, curtain rod, or a hook close enough to grab without standing
- Non-slip mat both inside the shower and on the bathroom floor outside it
- Clean clothes in the bathroom so you don’t have to navigate wet floors to another room
- Your crutches or walker leaning against the wall right next to the shower exit
If you’re using a tub transfer bench, position your crutches on the outside end of the bench so you can reach them the moment you slide back out.
During the Shower
Keep your broken leg elevated slightly or extended out in front of you, angled away from the main stream of water. Even with good waterproofing, there’s no reason to blast water directly at your cast. Use the handheld shower head to wash your upper body and your uninjured leg, then carefully reach what you can of your injured leg above and below the cast cover without shifting your weight off the seat.
Go slowly. Rushing is when accidents happen. Soap your hair and body methodically, rinse thoroughly, then turn off the water before you attempt to stand or transfer out. Dry off as much as possible while still seated, especially your hands, so you have a solid grip on your grab bar or crutches.
After the Shower
Remove your cast cover carefully once you’re out of the shower and stable. If using the duct tape method, peel the tape gently to avoid pulling skin. Check the inside of the bag for any water. If your cast feels damp, cool, or smells musty, contact your orthopedic provider. A hair dryer on a cool setting can help evaporate minor surface moisture at the edges of the cast, but it won’t fix water that’s soaked into the padding underneath.
Pay attention to the skin around the edges of your cast over the following days. Early signs of moisture-related skin damage include persistent redness, itching, or a white, swollen appearance where the skin stays wet too long. If you notice a foul smell, increasing pain, or red streaks, that can signal a secondary infection developing under the cast. These problems are treatable, but they get worse quickly if ignored.
Alternatives When Showering Feels Too Risky
In the first few days after your injury, when pain and swelling are at their worst, a full shower may not be worth the effort. A sponge bath while sitting on the edge of your bed or on a sturdy chair in the bathroom accomplishes the same hygiene goals with far less risk. Fill a basin with warm soapy water, wash in sections, and rinse with a damp cloth. Many people alternate between sponge baths on harder days and full showers when they’re feeling steadier. There’s no rule that says you have to shower every day during recovery, especially in the first week or two when mobility is most limited.
