At only 1.28 gallons per flush (GPF), the Toto Ultramax II is one of the most environmentally friendly toilets available. Even though water-saving toilets are extremely popular right now, most still require at least 1.6 gallons or more to create a good flush. The Toto Ultramax II takes it a step further without sacrificing flushing power.


Toto Tornado Flush System

The Toto Tornado flush is another way this toilet improves on the traditional style. This flushing system pulls water into the bowl during the flush to create a cyclonic action that helps clean the bowl as it captures the waste before exiting with powerful force.


The CEFiONTECT glaze is a baked-on coating that provides a smooth surface inside and out of the bowl that prevents material from sticking to it and reduces friction between waste material and the toilet creating a stronger flush a cleaner toilet that requires less maintenance.

Universal Height

There are three toilet heights commonly used in the United States. The standard height is between 13 and 15-inches tall to the seat. The universal height, which this toilet is, is between 15 and 17 inches tall from floor to seat. The Ultramax II is 16.8 inches floor to the seat before installing the soft close lid and 17.25 when complete. Comfort height seats are even taller at 17 to 19 inches above the floor.

These taller seats are much easier to get up and down from, especially if you are taller or have back or leg problems. However, many doctors say it’s a good idea to use a step stool once you are seated to get into a better position when using them. The step stool does not need to be large or expensive to be functional, and it can help reduce the risk of the onset of hemorrhoids and constipation.



What do you use to clean cefiontect glaze?

The instructions say to use a gel toilet cleaner. Many people recommend Dawn dish soap as well, along with a soft brush or cloth. You cannot use bleach or any bleach products as it can remove the protective glaze.

What is the rough-in for this model?

It is a standard 12-inch rough-in.

Does this come with the seat included?

Yes, the seat comes with the toilet.

Is the tank insulated, so it doesn’t sweat?

No, the tank is not insulated. However, we have never experienced any sweating.

Is the seat easily removed?

Yes, the seat attaches with two plastic bolts.

Is this a two-bolt or four-bolt installation?

It’s a two-bolt installation.

What else will I need to install this on my own?

To install the toilet, you will need a new wax ring for sure, and you may also decide to install a new inlet hose to run from the water valve to the toilet.
