The Aquia® Dual-Flush Elongated Two-Piece Toilet with Tornado Flush (Seat Included) is designed to conceal the Washlet® power cord and water supply hose for a seamless installation. Part of the newly redesigned C series, the Washlet® C5 features 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 C5 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 soft close seat with five temperature settings. The Washlet® features an air deodorizer and a warm air dryer with five temperature settings. The Aquia®IV Cube features TOTO's Dynamax Tornado Flush®, utilizing a 360-degree cleaning power to reach every part of the bowl. This version of the Aquia®IV 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 enhanced design of the Aquia®IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. Allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The sleek tank design coupled with the skirted bowl creates a sophisticated look and minimizes the need to reach behind the bowl to clean in between the nooks and crannies of the exterior trapway. Designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. The Aquia®IV Cube comes ready for installation into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines. Compatible with T40 Washlet®+ electronic bidet seat and toilet bowl components only.
