The TOTO® WASHLET®+ Ready WASHLET® S300e Elongated Bidet Toilet Seat with EWATER+® delivers ecology-minded luxury in a slim design. 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 WASHLET+ Ready WASHLET S300e Elongated Bidet Toilet Seat 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+ 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 S300e is fully automated, including an illuminated remote control with 5 spray settings, heated seat, and instantaneous water heating. Using a 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 WASHLET models are designed to work with TOTO T20 WASHLET+ ready toilets only. If you are looking for a WASHLET bidet seat to fit your existing toilet installation, please look for WASHLET models that do not contain WASHLET+ in the description.
