Design

As you see in the picture, the toilet has an elongated bowl but only a small tank. There are many toilets which come in a 1.6 gpf and 1.28 gpf version, without any exterior differences. In those cases the only difference is inside: different flush valves. This toilet is designed for the 1.28 gallons per flush, giving it a small tank. It looks great in smaller bathrooms. The trip lever is chrome colored. The rim is clean without holes (due to the flushing system, read on).

Installation

Hassle free. A normal installation with a wax seal and bolts. There is relatively little room left behind the toilet (rough-in 12 inches). Like all one-piece toilets they are heavy (as you cannot carry the tank and bowl separately) and are therefore more difficult to position.

Flushing

The toilet uses Double Cyclone flushing technology and has a SanaGloss ceramic finish, a smooth finish to keep the toilet extra clean. The toilet has two individual nozzles pointed in the bowl, these nozzles cause the water to move in a circular manner, causing a whirlpool effect. This clean the bowl thoroughly and educes waste buildup. The flush uses 1.28 gallons of water, making it a high efficiency toilet that is WaterSense certified. The trapway is standard with a diameter of 2-1/8. The MaP score is, as most toilets, above 1000. This is the maximum score. The MaP (maximum performance) is an independent and reliable score to indicate the flushing power of a toilet.

Past problems

There are consumer reports and some topic on forum addressing problems with the water filling valve easily breaking. You recognize the valve by its green top. These problems were noticed by Toto and since years they have been replaced. You find older reports of people complaining about the toilet, but since years there have been no new reports of problems with the valves.

Consumer opinions

We read and summarize all the user opinions, so you don’t have to. We hope this will give you a balanced opinion of the pros and cons!

Positive

  • Strong effective flush
  • Quiet while flushing, but also reasonably quiet when filling
  • Very rarely needs a second flush
  • Clogging is rarely reported
  • The toilet comes with a soft close seat
  • The water tank refills fast.

Negative

  • Although very good quality still too expensive for what you get.
  • Too high (18 inch seating height)
  • Needs in depth cleaning

Neutral (“things good to know”)

  • Flush takes about 30 seconds to complete
  • Short depth of the toilet wall to front

Conclusion

The Toto Ultramax II is a somewhat expensive one-piece toilet. It is a big plus is that a toilet seat is included. This is not to case for the majority of toilets. A soft close seat can easily cost more than 50$, and as this is included the toilet in totality is not so much more expensive than its competitors. The flush is effective and keeps the bowl clean (the smooth ceramic finish, SanaGloss, might contribute to this too). The small one-piece design, powerful flush with ‘whirlpool’ effect makes it a very good toilet to install in small places. The toilet uses just 1.28 gallons per flush, making it a high efficiency toilet and deserving of the WaterSense label.

If flushing power is very important and you still fear the toilet might clog (although the Ultramax II does not have this reputation!) you might want to consider the American Standard Champion 4 one-piece toilet (read the review here). This toilet has a significantly larger valve and trapway, making clogging even less likely and is less expensive.
