Advanced Surface Protection

The CEFIONTECT glaze creates an extraordinarily smooth ceramic surface that helps keep the bowl cleaner longer. By preventing debris and mold from adhering to the porcelain, it ensures that standard routine cleaning requires much less time and effort. A common feature in Toto One Piece Toilets.

Cyclonic Bowl Rinsing

The TORNADO FLUSH system utilizes two powerful nozzles to create a centrifugal, cyclonic rinsing action with a 1.28 GPF volume. It delivers a strong and efficient clean with every flush, sweeping away waste while using less water. Found in many Toto Ultramax models.

Seamless Single-Unit Body

The one-piece configuration integrates the water tank and lower bowl into a single, continuous ceramic unit. This removes the separate tank-to-bowl connection gap found on traditional setups, eliminating a common hiding spot for dirt and making external wipe-downs much faster.
