You can browse this website for descriptions of Toto toilets. Just start at the upper left of this page and click "Toilet Reviews". This takes you to a different section of this site. Now click on "Shopping". On the page that comes up, click on "Toto Toilets". You should realize that the prices listed are what Terry sells them for. Your local shop may charge more, but virtually no one sells for MSRP. Besides ADA height, you might want to consider Universal or Comfort Height. These are just a little lower than ADA, and may work OK for you. You should check your rough in size before shopping. Measure from the bolts that hold the toilet to the flange to the finished wall behind the toilet. While 12" rough in is the most common, a toilet sold as a 12" usually will fit in less space. The tank will just set closer to the wall. Come back here if you have additional questions.
