The TOTO WASHLET S7A Round, Auto Flush Ready Bidet Toilet Seat with EWATER+ and Auto Open/Close Contemporary 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 WASHLET S7A Round can be installed on round toilets. 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. The TOTO WASHLET S7A is operated by a luxury style illuminated wireless remote with 4-user memory storage to save preferred settings. The WASHLET features 5 spray settings, auto open and close lid, Auto Flush compatibility (kit sold separately), heated seat, a night light, and instantaneous water heating. The contemporary 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.
