Aquia® IV Dual-Flush Elongated Two-Piece Toilet with High-Efficiency Flush (Seat Included) is the epitome of modern form and function. The sleek tank design coupled with the skirted bowl enhances the elegant look of the toilet and adds a level of sophistication. Skirted design toilets conceal the tramway and minimize the need to reach behind the bowl to clean the nooks and crannies. The aqua iv cube features TOTO's Dynamax tornado flush, utilizing a 360-degree cleaning power to reach every part of the bowl. This version of the Aquia iv includes Cefiontect® technology, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with Dynamax tornado flush, helps to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia® IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The aqua iv bowl and tank set include a softclose® seat, tank-to-bowl hardware, a tank-to-bowl gasket, outlet socket, and toilet bolt caps. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines
