Abstract: This integrally formed water and space saving lavatory-toilet fixture enables hand washing with potable water from an existing toilet, recycles effluent completely, and provides sanitary, seamless, one-piece, full perimeter tank closure. A flexible hose re-directs supply away from the overflow through an interior fixture cavity and top cast opening toward a basin, that drains back into the reservoir as effluent; supplementing the required volume of water to complete one flush cycle. A cast sidewall basin opening is formed allowing potential drainage to flow through an internal hollow cavity directly into the tank reservoir below. The integrally formed fixture also includes a sloped front wall allowing additional hand washing space, vertically aligned space saving side and rear walls, and, an integrally formed perimeter rim conforming to the shape of the toilet tank edging below, providing hygienic, continuous tank containment and secure, detachable mounting.
