A pedicure bowl has a bottom discharge drain opening communicating with a discharge duct and is arranged to receive a liner to ensure hygienic operation in the form of a thin flexible material applied over the inner surface to contain the liquid within the liner and to cover the drain opening. The drain opening is closed by the liner so that liquid within the container applies downward pressure on the liner at the drain opening and a sealing member is mounted in the duct downstream of the drain opening to prevent air flow so as to form a back pressure underneath the liner to prevent the downward pressure from rupturing the liner. The sealing member is operable to release the back pressure to cause the liner at the discharge opening to rupture.
