A bath for a disabled person, the bath having a body with a side opening which is closable by vertically displaceable door under the action of a door movement mechanism including a counter-weight beam (56) either end of which is linked to an end of the door by a chain. The weight of the counter-weight beam (56) is selected so as to bias the door towards its closed position. The beam (56) is connected by a pin (66) to over-centre lockable link arms (60, 62). When the beam approaches its lowermost position, as the door closes, a stub portion (72) of a pivot pin (64) connecting the link arms (60, 62) enters a locking fork (77) which is displaced by a motor (82) to effect over-centre locking of the link arms (60, 62) and thereby seal a channel on an inner face of the door against a lip disposed around the opening.
