TOTO washlets have set the industry standard for electronic bidet seats for over 2 decades. With unwavering quality and the latest technology, TOTO washlets are still widely considered the gold standard. TOTO's newest fleet of washlet seats include the TOTO S350e Washlet with auto open/close lid and the TOTO S300e Washlet. These fully featured bidet toilet seats have a number of unique features not found on other washlet brands. The TOTO s350e features an auto open/close lid that will automatically raise or lower the lid when a user approaches or leaves for a truly hands-free experience. Both the s350e and s300e washlets come with TOTO's new ewater+ function that pre-mists the toilet bowl to keep it cleaner between uses.
