The temperature and pressure of the water are adjustable, each with five settings. The controls are located on a slim, wireless remote. The PREMIST function sprays the bowl with water before each use, preventing waste buildup and keeping the toilet bowl clean. The wand is self-cleaning, automatically cleaning itself with EWATER+ electrolyzed water 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 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 gal of water. The skirted design of the AP 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 prevents particles from adhering 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. The DuoFit® harness allows you to select a mounting height of 15 to 19 in. 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 880 lb when installed properly. The kit arrives ready to be installed within a 2 x 6 in stud setting with a 2 x 6 in polyethylene waste outlet. If you require installation within a 2 x 4 in setting, you can purchase Toto®'s 2 x 4 in PVC outlet kit (THU343).
