Described as having a "remarkable" three-second flush, as well as being a "good looking, high performance" toilet, the Toto UltraMax has a very thorough flush, leaving nothing in the bowl, and can handle loads as large as 700 grams. The toilet is equipped with a 3-inch G-Max flapper assembly, instead of the standard 2-inch, which allows the water to drop faster to create a more powerful flush.
