The toilet arrived well packed and undamaged. I went with the measurements given - thinking the advertised measurements were for the item purchased. This toilet does not come with a seat - must be purchased separately. HOWEVER - their advertised height includes the separately purchased seat. They seem to be assuming we purchase the same seat and I made the mistake of thinking the companies advertised measurement was for the item I purchased.  What you purchase is 16.5 inches tall. It works but I had been excited thinking I had found a 17.5" tall toilet.
