The Aquia IV one-piece elongated dual flush 1.28 and 0.9 GPF Universal Height WASHLET®+ ready toilet is the epitome of modern form and function. 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, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The chrome center-mounted push button that sits atop the tank 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. The TOTO Aquia IV 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. Includes a SoftClose® toilet seat (#SS124). Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.

TOTO MS646124CEMFN Technologies and Benefits:
SoftClose® Seat: The seat and lid utilize a built-in SoftClose® hinge system, which lowers the seat and lid down to the bowl gently and quietly.
DYNAMAX TORNADO FLUSH®: Uses 100% of water to clean and rinse the bowl using a smaller amount of water more efficiently with a 2.5” trapway and quieter flush. Available in 1.0/.9 GPF or 1.28/.8 GPF.
Universal Height: Toilet height that allows for a more comfortable height position across a wide range of users.
Skirted Design: The Skirted Design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted Design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway.
