A potty (10) includes a sidewall (12), basin (14) and a top surface (15) including a seating surface (18). The potty (10) is arranged such that it can be stacked with a similar potty such that a part of one is received within the other. This results in the combined height of the stacked potties being less than twice the height of an individual potty. The potty (10) has a duct (20) that enables liquid to be poured from the basin (14) out of the potty substantially without coming into contact with the seating surface (18).
