TOTO UltraMax One-Piece Toilet

TOTO UltraMax One-Piece Toilet with E-Max Flushing System

The TOTO UltraMax is a sleek, one-piece toilet engineered around TOTO's commitment to "People Planet Water." Available in elongated and round bowl configurations, standard and ADA-compliant heights, 1.28 GPF and 1.6 GPF flush volumes, and with or without CEFIONTECT ion-barrier glaze, this listing covers the full UltraMax family — select your exact configuration using the options above.

The seamless one-piece construction eliminates the tank-to-bowl joint found on two-piece toilets, removing the gap where dirt and debris accumulate and eliminating the risk of leaks from bolts or gaskets. Cleaning is faster and more reliable — a meaningful advantage in multi-unit residential, hospitality, and commercial restroom applications.

E-Max Flushing System

The E-Max system combines a 3-inch wide flush valve, an extra-large siphon jet, and a full-size 2.125-inch trapway to generate a powerful, quiet, clog-resistant flush. At 1.28 GPF, it meets EPA WaterSense, California CEC, and CALGreen requirements — qualifying for water-efficiency rebates in most jurisdictions. The 1.6 GPF option is available for projects where code or preference requires the higher flow rate.

CEFIONTECT Glaze (Optional)

Select variants include TOTO's CEFIONTECT ion-barrier glaze — an ultra-smooth ceramic surface that prevents waste, mold, and bacteria from adhering to the bowl. This reduces the frequency and intensity of cleaning required, lowering maintenance labor costs in high-traffic commercial and multi-family settings.

ADA-Compliant Height Option

ADA-compliant variants feature a 16.5625-inch rim height, meeting Americans with Disabilities Act requirements for accessible restroom installations. Standard-height variants have a 14.625-inch rim height. Confirm ADA compliance requirements for your project before selecting.
