TOTO Nexus 1G WASHLET+ S7 Two-Piece Toilet 1.0 GPF MW4424726CUFG#01 / MW4424726CUFGA#01
The TOTO Nexus 1G WASHLET+ S7 pairs the skirted Nexus two-piece elongated toilet with the WASHLET+ S7 bidet seat. The 1G configuration uses an ultra high efficiency 1.0 gallon per flush TORNADO FLUSH system. As a WASHLET+ system, the power cord and water supply are concealed for a clean, integrated look. CEFIONTECT ceramic glaze helps prevent waste from adhering to the bowl. Universal Height seating and an elongated bowl provide everyday comfort.
Choose the version with Auto Flush (MW4424726CUFGA#01) or without Auto Flush (MW4424726CUFG#01).
