Equipped with a 1.28-gpf Double Cyclone Flush Engine, the Drake II HETs from TOTO USA use a water-efficient, gravity-fed flushing system that, in addition to saving water, cleans the bowl with every flush. The contemporary two-piece toilet also features a concave rim design to facilitate easy cleaning and the company’s SanaGloss Glaze, which seals the porcelain with an ionized barrier and creates a slippery, nonporous surface that repels waste and bacteria.
