Yes, a bath or shower can be taken when wearing a stoma. It is someone’s personal choice whether they leave the bag on or take it off, as water cannot get into either the stoma or the bag. If the bag is removed though it’s a good idea to have the bath or shower at a time of day when the stoma is less active. If the stoma bag is left in place and there is a filter that lets gas escape it is a good idea to cover it with a sticky patch during a bath or shower, as the filter will become less effective if it gets wet.
