Sigma30 is the latest addition to the family of flush plates for Sigma in-wall toilet systems. Available in two versions: a single-button model with stop-and-go flush that stops flushing at a touch and a water-saving dual flush model with two large, rectangular buttons. Both styles are available in a range of finish options to match any décor. The stop-and-go flush model offers four finish options, a large button for easy flushing and is made of die-cast zinc. The water-saving dual-flush model offers six color options and is made of injection-molded plastic.
