Answer: 
Toto does have a 10" model--the printed template includes both--be sure you order the correct model number if you need the 10" rough-in. Toto model number is CST412MF.10 for 10" rough-in.

Answer: 
18 inches, but Note:
This is with the seat and cover that Toto recommends for this toilet on their own website. It's not the unit that HD offers for it. That seat/cover combination might be a bit lower, judging from the respective photos.

I understand that most Toto toilets come with an easy to clean sanigloss finish. Does the Aquia II 2-piece dual flush toilet that Home Depot sells comes with a sanigloss finish?

Below the Home Depot listing for the toilet, there is a package offered. Toilet, Toto Soft-Close Seat and Wax Ring for installation. EZ!

Rated 4.2 out of 5 by 57 reviewers.
Rated 4.0 out of 5.0 by Best toilet I have ever had and the worst directions I have ever seen. Directions where the worst. The parts used to assemble the tank where completely foreign to any toilet I have ever installed. Granted I am not a professional, but also not a moron. The pics on the directions where 1 inch square with no online pdf available. Ended up cracking toilet due to poor instructions. Regardless the toilet is very nice and works flawlessly. August 9, 2016
Rated 5.0 out of 5.0 by great toilet great toilet! now if I can only remember to use the buttons accordingly ;P August 23, 2016
Rated 4.0 out of 5.0 by Nice toilet Nice toilet. For the price, it should come with a seat... Why doesn't it come with a seat??? That and the price = minus a star. It's very easy to clean which I like a lot. Flush is great and bowl design is great! Very difficult to install so if you're not highly mechanically inclined - I would suggest having someone do it for you. This one is not straightforward. July 20, 2016
Rated 5.0 out of 5.0 by Great toilet As far as a toilet goes, it looks great! Artistic even. Installed it myself in about 2 hours as it is not a standard installation but not too difficult -- This Old House has a video on installing this exact toilet (search for "install dual flush toilet" on Youtube) that helped a lot. Cleans easily. December 24, 2015
Rated 1.0 out of 5.0 by Should have went with a Kohler While Toto has a very nice reputation for good-performing toilets, this one has left me frustrated and wishing I had went with the Kohler brand which has served me so well previously. The specific issue is that the tank-to-bowl connection consistently leaks. It's a poorly designed interface that is prone to leaks and is difficult to resolve. I've taken it apart numerous times, cleaned the seal interfaces, re-tightened all bolts and connects, and it continues to leak. It's a direct result of their poor seal designs and interfacing surfaces. I hope others have had better luck, but I will not be buying Toto again in the future. May 15, 2016
Rated 5.0 out of 5.0 by Darn good toilet! This is a great overall toilet. Supreme flushing with a big target area. If your a first time toilet installer, make sure you have a hammer drill with an 11/32" masonry bit if your drilling the anchors into concrete. Everything else was easy to figure out. Took about an hour to methodically install it the right way in this fashion. Overall a great purchase! August 11, 2015
Rated 5.0 out of 5.0 by Great Style I wanted a Toto because I have spoken with many people who are very pleased with the brand. I love the style of the one I chose - it has a sleek look and looks great in my bathroom. I had to order online because of the brand and the first one arrived with a slight crack in the bowl which was very disappointing. Home Depot was great about shipping a new one to me within a few days and the return was easy. I am very pleased with the entire transaction. May 3, 2016
Rated 5.0 out of 5.0 by Excellent Toilet Every aspect of this toilet is nearly perfect. I ordered one of these and an Ultramax and tried them out for a month and decided the Aquia II is the better toilet. No issues with waste removal. Some complaints I've seen about staining or difficult to remove stains, but no problems for our family in use. Bought the second one now to round out the three bathrooms and am very pleased with the choice. The overall style is really nice. Makes the whole bathroom look fresh again. The size of the water spot is also not an issue as it's designed to funnel down into the bowl. Most every toilet in Europe is designed this way (i.e. small but deep water spot). The installation is slightly different than other toilets but is not complicated or hard by any stretch. There are two "posts" that you have to drill down into the floor and you in turn screw the toilet into these posts. The end result is a toilet that is literally attached to the floor and will not leave, move, or wobble even under the most extreme circumstances (earthquake?). Anyhow, all went well especially if you find the "thisoldhouse" video and prefer to see an installation instead of read the instructions. The only area of improvement I can think of is that for both Aquia's I installed, the flusher buttons needed a slight adjustment. There is a 1 page rider in the instruction book that shows how to do this. It is really easy (i.e. unscrew a plastic post one turn per millimeter adjustment - I had to extend mine by 2 mm). I suggest you take the tank lid off and press each button with your finger. Press to the bottom of the pushbutton and let go immediately. Do not hold the button down for some number of seconds, just press and let go. The mechanism will let the proper amount of water out automatically. Watch how the toilet flushes. Then return the tank lid and try with the buttons on the tank lid. If it does not flush completely as before, simply extend the rod by 1 mm until it does. May 22, 2016
