Do you have a Medmart Shower Shield that has come to the end of its usefulness because the Velcro is no longer holding while you take your shower? If the stoma guard is still in good condition, rather than buy a new Shower Shield, consider replacing the Velcro. Buy a length of 20mm wide Velcro from a sewing shop or department store. Carefully unpick the old Velcro from the Shower Shield. Cut lengths of new Velcro to match the discarded pieces. Stick the new Velcro in place on the Shower Shield and hand sew through the holes left from the previous cotton. There, you have a new Shower Shield, or as good as new.
