Toilet with 18 inch rim height

Hi,
In researching for a toilet bowl with a higher than average rim height, I stumbled across your website. I read a question posted in 2003 regarding a search for a toilet bowl with an 18 inch rim height by a gentleman who was moving from a handicapped accessible home. I am currently on a hunt for such a toilet and was wondering if you have come across this item since the request was made. I'd greatly appreciate your sharing of this information.
Thank you.

There is a company that makes bases that seal on the flange, then the toilet seals on the base. You can get to 18" that way.

You'll likely find what you want by getting a thick (tall) toilet seats. Handicapped (ADA) toilet rims are at 16-16-1/2" rim height and standard toilet seats are about 1" to acheive the min. 17" handicap height.

Is this for a tall person or a handicapped person?
Google turns up this:

With and without legs and other variations. Found Here
