Geberit’s Sigma21 is a new flush actuator series for its concealed tank and carrier systems. The new actuators provide designers and architects with finish choices not available from any other manufacturer, Geberit states. In addition to white, black and sand-glass finishes, Sigma is available in genuine Brazilian slate, providing a transitional design motif that complements traditional as well as contemporary bathrooms, Geberit adds. Sigma 21 also is available with a customizable overlay that can be personalized to seamlessly blend with the wall or create a unique design statement. The Sigma 21 flush plate is designed to reliably operate and allow for easy accessibility for maintenance, while achieving maximum water savings when used in conjunction with Geberit dual-flush in-wall toilet tanks.
