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 wand is self-cleaning, using TOTO's EWATER+ system before and after every use.

The DuoFit® tank provides a WaterSense® certified dual-flush option with TOTO’s DYNAMAX TORNADO FLUSH. A hole-free rim design that generates a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. The skirted design of the EP bowl conceals the trapway, 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 TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning.
