The TOTO WASHLET+ S550e 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. Designed for use with TOTO T40 WASHLET+ toilets. WASHLET+ T40 toilets feature a channel on the bowl surface to help conceal your WASHLET+ supply line and power cord for seamless integration. 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. A once mundane trip to the bathroom can become a spa-like experience with a WASHLET. The WASHLET features TOTO's technologically advanced ewater+ system which uses electrolyzed water generated by a technologically advanced process, transforming the water into a safe and powerful compound. By misting the bowl after every use, the ewater+ technology helps to keep your toilet bowl clean and hygienic without any extra harsh chemicals. The Premist function sprays the bowl with water before each use, preventing waste buildup and keeping the toilet bowl clean. The TOTO WASHLET S550e is operated by a luxury style illuminated touch pad remote with sliding action and 2 user memory to save preferred settings. The WASHLET features 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The newly redesigned classic lid couples well with a traditional bathroom style. The minimalistic display provides a more subdued appearance to your WASHLET. The WASHLET reduces the need for toilet paper, saving trees and water used to manufacture each roll. As we get older, our mobility can deteriorate and make it increasingly hard to clean ourselves after toileting. Medical conditions and debilitating illnesses can make using the bathroom without assistance almost impossible. With a WASHLET, just the touch of a button can leave you feeling clean. Includes mounting and connection hardware.
