ANSI 117.1a 2003, which is determined to be "SAFE HARBOR" for accessible design, requires that an accessible toilet be 17" to 19" in height. Most regular toilets are 14" to 16" in height. Therefore, about 2 to 4" is the difference between ADA and regular toilets. I also checked the spec. sheet for this toilet on Eljer website. According to the spec. sheet, this toilet is an ADA toilet.
