The TOTO T40 Nexus One-Piece Elongated 1.28 GPF WASHLET+ and Auto Flush Ready Universal Height Skirted Toilet with CEFIONTECT has a sleek and clean high-profile design, upholding TOTO’s vision to create a culture of comfortable, healthy living. The TOTO Nexus features a modern, one-piece design that will instantly elevate any bathroom décor. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, dirt and debris have no place to hide. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The Skirted Design of the TOTO Nexus conceals the trapway, which enhances the fluid design of the toilet and adds an additional level of sophistication. Skirted Design toilets also eliminate the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway. The TOTO Nexus features TOTO’s TORNADO FLUSH, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the TOTO Nexus includes CEFIONTECT, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. This feature, coupled with TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. This one-piece toilet is designed in TOTO’s Universal Height, which allows for a more comfortable seat position across a wide range of users. This version of the Nexus is TOTO T40 WASHLET®+ and Auto Flush Ready for when you are ready to upgrade to a hands-free flush system with electronic bidet seat. WASHLET®+ toilets feature a channel on the bowl surface to help conceal your WASHLET®+ supply line and power cord creating a seamless integration. The Nexus comes ready for install into a 12" rough-in, but may be adapted for a 14" rough-in with the purchase of a separately sold adapter. The Nexus is ADA compliant and meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. Features a left-hand chrome trip lever. Does not include seat or WASHLET. Additional items needed for installation and use must be purchased separately: compatible toilet seat or T40 WASHLET+, wax ring, toilet mounting bolts, and water supply lines.
