The TOTO T40 WASHLET+ Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and WASHLET C5 Bidet Seat 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 SoftClose seat with five temperature settings. The WASHLET features an air deodorizer and a warm air dryer with five temperature settings. The Aquia IV features TOTO's DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl.

This feature, coupled with the WASHLET PREMIST and DYNAMAX TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning.
