The TOTO T20/T40 WASHLET plus Auto Flush Ready S7 Elongated Bidet Toilet Seat with EWATER plus and Auto Open and Close Classic Lid is an electronic luxury seat that cleanses you with endless warm water, providing an exceptionally clean feeling. Instead of traditional toilet paper that can sometimes be rough and often ineffective, the WASHLET quickly provides comfortable warm water cleansing at the touch of a button. When paired with a compatible TOTO WASHLET plus toilet, the T20/T40 WASHLET plus is designed to conceal the WASHLET bidet seat''''s power cord and water supply hose for a seamless installation. The WASHLET features TOTO''''s technologically advanced EWATER plus system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. No need to touch buttons or handles, and never worry about someone forgetting to flush. WASHLET S7 is operated by an illuminated touch button remote with 4 unique user profiles to save each person''''s preferred settings. The WASHLET features 5 spray settings, heated seat, nightlight, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. The WASHLET reduces the need for toilet paper, saving trees and water used to manufacture each roll. Medical conditions, age, and debilitating illnesses can make using the bathroom without assistance almost impossible; but with a WASHLET, just the touch of a button can leave you feeling clean. Includes mounting and connection hardware. Newly designed S7 WASHLET models are designed to work with TOTO T20/T40 WASHLET plus ready toilets to acheive a seamless look with no visible connection to your toilet, but are also compatible to install on standard elongated toilet bowels.
