Toto Soiree is ADA, elongated, skirted and one piece. Comes with Sanaglosss. I think Guinevere is the same.

Another endorsement for the Soiree (and Toto as a company). It might not meet your criteria for "fully skirted"--the back portion is not covered by the skirt (yeah, it does seem silly to me, too!), but it's still very easy to clean. Also, you can no longer get it in 1.6 gal (all 3 of ours are), but I think posts here re: the 1.28 gal have been positive.

Our three had shipped prior to Toto's modification of their Unifit (to address drip noise post-flush). Not only did they send us 3 new-style Unifits at no charge, they also sent a check to help defray the plumber's cost to uninstall/re-install the 2 Soirees thus far installed. I like companies that "do the right thing." :-)

Thanks for the suggestions. I'll look into the Soiree. I'm having trouble finding a local dealer so I imagine I'll probably order online but then is the issue of finding a plumber who'll install my toilet. One guy I talked to said he doesn't install them. How difficult can it be? Sheesh, I assume the installation is pretty much the same on all of the major brands. But I think part is that they don't get the markup on the fixture too. Argh.

We just put the Soiree in our powder room and love it! It meets all your requirements., ADA height, 1 piece, fully skirted, etc. It is a bit of a tricker install than your basic run of mill toilet, however if you get a plumber who really knows what he is doing there should be no problem. Another nice thing about the Soiree is that it comes with a toilet seat, so it is a perfect seamless looking fit. If you have to order it online you might want to look at homeclick.com. They are an authorized retailer of toto products. We almost did that but our plumber got us a great deal from a local supply place that was about the same price. Hope this helps.

I didn't read cat mom's post before I posted but she is right the skirt doesn't go fully around the back but since I can't see it back there, I still think of it as fully skirted. Oh, and we have the 1.28 gal and have had no issues at all. It works great!

Ours not installed yet but the Carlyle 11 Model # MS614114CEF(G) is one piece, elongated bowl, ADA, skirted, Sani Gloss, etc. Not sure if back is open - it's still in the box!

Still not sure which toilet to get. I thought I was set on Toto until I read about American Standard on GW. I'm considering American Standard Champion 4, check it out on the home depot website. It is a 2 piece, has a 4 inch valve, 1.6 GPF, elongated seat, comfort height, & everclean surface (sounds equivalent to Toto Sanagloss). Even comes with a soft close seat for $234.

Love, love, love our 1.28 gal Soiree. Have had it in for about 4 months. Plan to buy 2 more as replacements in other bathrooms eventually.

cynic writes: 1.6 gal. is fine, No advantage to me to go less than that. Dual flush is not anything special to me either.
Was looking at Vespin, Carlyle, Carolina and UltraMax. UltraMax seems to be the only one of these that have ADA height though unless I'm misreading something.

We have a Vespin II, installed eight months ago. It is ADA height, skirted, and it uses 1.28 gallons per flush; it flushes completely time after time. It is a good solution for our needs. But it is a two-piece.

If you want a stylish one-piece that has every technological innovation that any Toto has, look at the Inax Dover. Inax is the #2 market share toilet maker in Japan, and is the innovation pioneer in the world's most competitive toilet market. Most of the features in Toto toilets appeared first in an Inax model in Japan.

Among others, Terry Love (with whom you are familiar) sells the Inax Dover.
