The toilet style falls a little short on this unit. It certainly is not a fancy unit and good for a spare bathroom.  The unit is very very compact so for tiny rooms and shorter legs, it is perfect.  I thought dual flush would be a nice difference in what I am used to. There is nothing on the unit referencing water efficiency.  I also hired a plumber and the charge is extra for a single unit that is skirted.  Also, it fits so close to the wall so the water pipe had to be extended... be sure to keep this in mind as it is extra plumbing work.  I would say this toilet is ok and does have a quiet flush.  Overall, it is smallershorter than expected and could certainly improve on style.
