The TOTO T40 WASHLET+® Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and Auto Flush Contemporary WASHLET® S550e Bidet Seat is designed to conceal the WASHLET® power cord and water supply hose for a seamless installation. The WASHLET® S550e features TOTO's technologically advanced EWATER+ system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. PREMIST® wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The TOTO WASHLET S550e is operated by a luxury style illuminated touch pad remote with 2 user memory to save preferred settings. The WASHLET features 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The redesigned WASHLET lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. This minimalistic display provides a more subdued appearance to your WASHLET and skirted design conceals the trapway, which enhances the elegance and style the toilet. The one-piece design is not only aesthetically pleasing, but by removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris and minimize the frequency of cleanings. The Universal Height design allows for a more comfortable seat position across a wide range of users. The Aquia IV features TOTO’s DYNAMAX TORNADO FLUSH®, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT®, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. CEFIONTECT, EWATER+, and DYNAMAX TORNADO FLUSH create a synergy that optimizes flush performance 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. New Auto Flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to 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. 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. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines.
