This toilet is comfort height.
This toilet is comfort height, and the bowl is at 16 and 1/4th inches. That means with the seat, you'd actually be sitting at 17.5 inches.
While the spread should be a standard size, you would want to measure the rough-in. The rough-in is the distance between the finished wall and the center of either of the bolts that bolt the toilet to the ground. This toilet is made for a 12" rough-in.
I would recommend the SS114#01. This is the standard slow close seat by Toto.
