Abstract: A nail bath (1) has a surface (7) provided with one or more wells (8) for nail treatment solution. The one or more wells (8) have a disposition generally corresponding to the positions of the ends of the fingers and thumbs of one or both hands of a user. A cover (4) cooperates with the surface (7) to define a housing (2) in which the surface (7) serves as a floor. The housing (2) substantially encloses a space defined between the floor (7) and the cover (4), apart from a single opening (3), in the case of a one hand nail bath, or two openings, in the case of a nail bath for both hands, through which the hand or hands of a user extend(s) into the enclosed space during use of the nail bath.
