The TOTO(R) Aurora(TM) 1G(R) One-Piece Elongated 1.0 GPF WASHLET(R)+ and Auto Flush Ready Universal Height Skirted Toilet has a sleek and clean high-profile design, upholding TOTO's vision to create a culture of comfortable, healthy living. The TOTO Aurora features a modern, one-piece design that will instantly elevate any bathroom décor. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, dirt and debris have no place to hide.The TOTO Aurora features TOTO's industry-leading 1G technology, offering a powerful flush that flushes completely and fully with only one gallon of water. The TOTO Aurora features the power of our INTEGRAVITY SYSTEM(TM): An efficient flushing mechanism that directs even more water around the bowl at a higher velocity. Coupled with TORNADO FLUSH, these two features create powerful centrifugal washing action, rinsing the bowl more efficiently. This one-piece toilet is designed with Universal Height, allowing for a more comfortable seated position across a wide range of users. This version of the Aurora offers TOTO T40 WASHLET+ and Auto Flush compatibility for when you are ready to upgrade to a hands-free flush system with electronic bidet seat. WASHLET+ toilets feature an opening on the bowl surface to help conceal your WASHLET+ supply line and power cord creating a seamless integration. The Aurora 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 Aurora is ADA compliant and meets the standards for EPA WaterSense(R), and California's CEC and CALGreen requirements. Features a left-hand chrome trip lever and includes TOTO SoftClose(R) seat SS124. Additional items needed for installation and use must be purchased separately: Wax ring, toilet mounting bolts, and water supply lines.
