I have two. I had the first one for three years, loved it, and bought a second one when I remodeled the next bathroom. The dual flush works well every single time. I have never had a problem. Never. In fact, we typically only use the small flush and it never fails to clear the bowl. The skirt, although I am not a huge fan of the modern look, is wonderfully easy to keep clean, and I am a huge fan of easy cleaning. One thing you will have to get used to is the small water surface area. Use the Toto seat - it will feel odd at first, but you will get used to it quickly. It is designed to (at the risk of being indelicate) get you pointed in the right direction to land solid waste in the water. If you get a different seat, you will end up cleaning the bowl more often. I have one more bathroom to remodel - it will also get an Aquia.

From my research a few months ago, you are correct. That is the only one that meets the criteria. I ended upnot going with it because of price. Here in Canada it runs about $600 or so. I ended up getting a Kohler Persuade. It's elongated, skirted, dual flush. It's not 1 piece but it does have the sanitary dam between the tank and bowl. And as for ADA, it's 1/4" short of meeting the ADA requirements so I figured that was good enough. Cost just over $300 if I remember correctly. So far I haven't had any performance issues. I also considered the Aquia III which was around $650.

Moccasinlanding, you are so sweet to have run around your house with your tank lid for me! You gave me an idea to do the same, as I realized I have both a Toto and an American Standard toilet elsewhere in the house. I am assuming that they would use the same white across models; of course that may not be the case, but I will take any data points I can in my obsessive bathroom frenzy. I lined up my tile, my vessel sink, and the two toilet tank lids. It turns out that the A.S. lid is a slightly creamier white than the Toto, but I think it is a better match for the sink and tile. The Toto is whiter than my other elements. So now I am back to thinking that the A.S. is the way to go. I do like the cleaner lines of the skirted Toto, but I'm not sure I like it $200 more, when this is a bath for a teenage boy. Plus I think that the skirting may make it look even whiter, since there will be more flat surfaces to reflect light. And it is not a one-piece. I think I'm reaching a decision here.... The next big thing I need to look at is seat size and "target" area. Have to say that toilet research has been enlightening, and has made me laugh a few times. Thanks so much for your help.

I've got a Kohler Persuade installed in my ensuite. Had it in there for 6 months now. No problems at all and is great to clean because of the skirted design. Most of the time a small flush is all that is needed. I'm a big guy and haven't had a clog yet. The Terry Love forum is great but they seem to be quite biased towards the Toto brand. I've got an Aquia II waiting to be installed in my main bathroom when I finish the reno's in there. I'm sure it will be a fine toilet.
