The TOTO T40 Washlet+ UltraMax® II one-piece elongated 1.28 GPF toilet and contemporary Washlet S7 bidet seat is designed to conceal the Washlet power cord and water supply hose for a seamless installation. The Washlet S7 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 S7 is fully automated, including an illuminated remote control with 5 spray settings, a heated seat, and instantaneous water heating. The UltraMax® II features TOTO's 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 TOTO UltraMax® II includes Cefiontect®, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with the Washlet Premist® and Tornado Flush®, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The TOTO UltraMax® II is designed in TOTO's Universal height, which allows for a more comfortable seat position across a wide range of users. This Washlet+ includes the Washlet with water supply adapter, UltraMax® II bowl and tank set with hardware, and toilet bolt caps. Compatible with T40 Washlet+ toilet bowl components only. Additional items needed for installation must be purchased separately: Wax ring, toilet mounting bolts, and toilet water supply lines.
