The Toto T40 Washlet+ Aimes® one-piece elongated 1.28 GPF toilet and contemporary Washlet+ S7A bidet seat are designed to conceal the Washlet+ power cord and water supply hose for a seamless installation. The Washlet+ S7A 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+ S7A is operated by a luxury-style illuminated touch button remote with sliding action and 4-user memory storage to save preferred settings. The Washlet+ features 5 spray settings, auto open and close lid, a heated seat, a nightlight, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamlined look and giving the impression of an integrated system. The minimalistic display provides a more subdued appearance to your Washlet+. Skirted design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The Aimes® features Tornado Flush®, a hole-free rim design with dual nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the Aimes® includes Cefiontect®, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. Cefiontect®, Ewater+, and Tornado Flush® create a synergy that optimizes performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The 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. Additional items needed for installation must be purchased separately: Wax ring, toilet mounting bolts, and toilet water supply lines. Compatible with T40 Washlet+ toilet bowl components only.
