How to bathe with a cast on your leg

Updated July 20, 2017

Plaster casts for broken limbs work only if they are kept dry. Bathing with a leg cast can be difficult because the affected leg should be kept out of the moisture of the shower or bath by balancing with one leg outside the shower or hanging the casted leg over the side of the bathtub. Chemists provide several different cast covers that fit over the cast and provide watertight protection. If you do not have access to one of these store-made products, however, you may resort to an alternative, homemade method.

Pull one of the garbage bags over your entire cast and tuck the top of the bag into the cast.

Tape the skin above the cast to the plastic garbage bag using medical tape, sealing all the way around the leg.

Place the second plastic garbage bag over the first one.

Use the duct tape to create a watertight seal between bag and skin. Place the duct tape over the existing medical tape.


Sit on a chair in the shower for extra support. Make sure you use sturdy supports and nonslip bath mats, to avoid accidents. Remove tape residue from the skin with baby oil.


Avoid placing the duct tape directly on the skin. Avoid letting the cast come in contact directly with moisture, even with the plastic bag protection. If possible, keep the foot outside the shower or bathtub.
