Toto | Aquia Toilet Base in Cotton White. The skirted design conceals the trapway, which enhances the elegant look of the toilet and also minimize the need to reach behind the bowl to clean the nooks of the exterior trapway. The bowl is designed to feature Toto's Universal Height which allows for a more comfortable seat position across a wide range of users. When paired with its tank, the Aquia meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat. Has a 12" rough in size with 1.6 GPF and 0.9 GPF. CT412F#01
