The TOTO UltraMax II 1G WASHLET+ One-Piece Elongated 1.0 GPF Universal Height Toilet with CeFiONtect is designed to work with a TOTO T20 WASHLET+ WASHLET. The WASHLET+ toilet features a channel on the bowl surface to run your WASHLET supply line and power cord for the purpose of concealing them. The TOTO UltraMax II 1G features a sleek, one-piece design that will immediately beautify the appearance of your bathroom. 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, we eliminate the hiding place for dirt and debris.

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 TOTO UltraMax II 1G features TOTO's industry leading 1G technology, offering a powerful flush that flushes completely and fully with only one gallon of water. The TOTO UltraMax II 1G 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 UltraMax II 1G 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 version of the UltraMax II 1G offers TOTO T20 WASHLET+ compatibility for when you are ready to upgrade. Compatible with T20 WASHLET+ electronic bidet seat models only. The TOTO UltraMax II 1G is designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users.

The UltraMax II 1G is ADA compliant and meets the standards for EPA WaterSense, and California's CEC and CALGreen requirements. The TOTO UltraMax II 1G has a left-hand chrome trip lever. Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, water supply lines, and TOTO WASHLET.
