Apparatus (10) for shielding a catheter from contact with water whilst showering, the apparatus (10) comprising: a first shield component (10(a)) having a first part (13) that is configured to form a first seal around an exit aperture (30) from which a catheter exits the patient's body, said first part (13) defining an internal volume (17) that opens to an internal volume (15) of a second part (15) that is configured to receive a distal part of said catheter； and a second shield component (25) for adhering to the patient's body around at least part of the periphery of the first part (13) of said first shield component (10(a)) so as to provide a second seal against water contact with said exit aperture (30)； wherein said first and second shield components (10(a), 10(b)) cooperate, when the apparatus (10) is worn by a patient, to resist water contact with said exit aperture (30) without obstructing access to an area of the patient's skin beneath said second part (15) of said first shield component (11).
