Another option is using a shield that directly adheres to the skin. The Stoma Guard ShowerShield secures around the stoma using a gentle adhesive. The disk has a front clear rubber housing with opening for unobstructed breathing. This allows a person to shower freely without worry.
The last waterproof option to apply to the stoma region is a barrier film. This No Sting Barrier Film designed by 3M is a unique product that's for one-time use. It's a transparent and breathable film that conforms well to the contours of the neck. It's easy to apply and dries quickly and dissolves in a solvent when needing to remove the film.
