The Aquia IV Arc two-piece elongated dual flush 1.28 and 0.9 GPF Universal Height toilet with CEFIONTECT is the epitome of modern form and function. The contemporary curved tank design coupled with the skirted bowl enhances the elegant look of the toilet and adds an additional level of sophistication. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. Allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. This version of the Aquia IV offers TOTO T40 WASHLET compatibility for when you are ready to upgrade. WASHLET toilets feature a channel on the bowl surface to help conceal your WASHLET supply line and power cord for seamless integration. The TOTO Aquia IV Arc meets the standards for EPA WaterSense, and California's CEC and CALGreen requirements. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. The Aquia IV bowl and tank set includes 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 *** Note: This item consists of multiple components and may ship in separate boxes, potentially arriving on different days. ***
