Overview & features
The TOTO T40 Aquia IV One-Piece Elongated Dual Flush 1.28 and 0.9 GPF Universal Height WASHLET+ and Auto Flush Ready Toilet with CEFIONTECT is the epitome of modern form and function. The skirted design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. 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 Aquia IV features TOTOs 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 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+ and Auto Flush 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 Universal Height design allows for a more comfortable seat position across a wide range of users. The TOTO Aquia IV meets the standards for EPA WaterSense, and Californias 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. Does not include seat or WASHLET. Additional items needed for installation and use must be purchased separately: compatible WASHLET or seat, wax ring, toilet mounting bolts, and water supply lines.
