The TOTO T40 Washlet+ Kit Aquia IV 1G two-piece elongated standard height toilet with automatic 1.0 and 0.8 GPF dual flush, and Washlet S500e bidet seat. The combo is designed to conceal the Washlet power cord and water supply hose for a seamless installation. The Washlet S500e features TOTO's advanced eWater+ technology which uses electrolyzed water transforming it into a safe and powerful disinfecting agent.

By misting the bowl after every use, the eWater+ technology helps to keep your toilet bowl clean and hygienic without any extra harsh chemicals. The Premist function sprays the bowl before each use to prevent waste buildup, keeping the bowl clean.

The TOTO Washlet S500e is operated by a modern illuminated touch pad remote with 2 user memory to save preferred settings. The Washlet features 5 spray settings, heated seat, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamlined look of an integrated system.

Skirted Design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The Aquia IV features TOTO's automatic 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 exceptionally smooth glaze that prevents particles from adhering to the ceramic. 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. The chrome center-mounted push button that sits atop the tank allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.0 GPF for tougher jobs.

The Aquia IV comes ready for installation 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. Compatible with T40 Washlet+ electronic bidet seat and toilet bowl components only.
