The TOTO T40 WASHLET EP Wall-Hung Elongated Toilet with S5 WASHLET Bidet Seat and DuoFit In-Wall 1.28 and 0.9 GPF Dual-Flush Tank System delivers style with innovative performance. WASHLET toilets are designed to conceal the WASHLET power cord and water supply hose for a seamless installation. Part of the newly redesigned S series, the WASHLET S5 features a built in night light, a soft rear spray, rear cleanse, and front cleanse with the option of an oscillating or pulsating stream. The temperature and pressure of the water are adjustable, each with five settings. The controls are located on a slim, wireless remote. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The S5 model utilizes TOTO's EWATER system when the wand self-cleans. EWATER transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand before and after every use. The WASHLET features a heated SoftClose seat with five temperature settings. The WASHLET features an air deodorizer and a warm air dryer with five temperature settings. The DuoFit tank provides a WaterSense certified dual-flush option with TOTOs DYNAMAX TORNADO FLUSH. This hole-free rim design generates a centrifugal, cyclonic rinsing action and allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.28 GPF for tougher jobs. The skirted design of the EP bowl conceals the trEPway, which enhances the elegant look of the toilet and adds an additional level of sophistication. This wall hung toilet bowl also features TOTO's CEFIONTECT glaze that minimizes waste from sticking to the ceramic. This feature, coupled with the DYNAMAX TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The DuoFit harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly. The kit arrives ready to be installed within a 2 x 6 stud setting with a 2'' x 6'' polyethylene waste outlet. If you require installation within a 2 x 4 setting, you can purchase TOTOs 2 x 4 PVC outlet kit (THU343).
