An adjustable lavatory drain assembly includes a receptor and a cover. The receptor includes a lower end and an upper end. The upper end of the receptor includes an outer flange. The cover is removably coupled to the upper end of the receptor. The cover includes a body having an opening defining a first flow path and a sleeve extending from a bottom surface of the body. The sleeve is adjustably coupled to the upper end of the receptor forming a circumferential gap between an upper surface of the outer flange and a bottom surface of the body. The cover is selectively adjustable relative to the receptor to increase or decrease the circumferential gap. The circumferential gap defines part of a second flow path.
