getting ADA height with non-ADA height units

we have a Toto Ultramax ADA height toilet that is great, both in function and height for our old tired bones

we are about to get three more Toto toilets for our new house--two come in ADA height, but we also want the Neorest 500

we are trying to figure out how to make the Neorest 500 seat the same height as the Ultramax -- we will be raising the base by sitting it on a piece of stone or Corian -- but cannot seem to figure out the dimensions

how far below ADA height is the Neorest 500?

anything else we need to know?

Ada Toilet Seat


GET A HANDICAP TOILET SEAT TO RAISE 2"" IS THE SIMPLEST THING TO DO!!!

If your looking at the Neorest 500, you cannot use a handicapped seat because the seat is a bidet seat.
The height of the 500 including the seat is about 16".
Without the seat it's standard height 14 1/2"
The normal height of a regular seat is 1" the Neorest seat is 1 1/2" Ultramax ADA would be 17 1/2" with a seat.
