The TOTO T20/T40 WASHLET+ and Auto Flush Ready S7A Elongated Bidet Toilet Seat with EWATER+ and Auto Open and Close Classic Lid is an electronic luxury seat that cleanses you with 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. The TOTO T20/T40 WASHLET+ Ready WASHLET S7A can be installed on standard elongated toilets or on TOTO T20/T40 Toilets which conceal the WASHLET bidet seat’s power cord and water supply hose for a seamless installation. The WASHLET features TOTO’s technologically advanced EWATER+ 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. The TOTO WASHLET S7A is operated by a luxury style illuminated touch button remote with 4-user memory storage to save preferred settings. The classic design lid is positioned flush with the toilet bowl, providing a streamlined look and giving the sleek 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. WASHLET+ Ready models are designed to work with TOTO T20/T40 WASHLET+ ready toilets to acheive a seamless look, but are also compatible with standard elongated toilets.
