Glad you're happy with the AS. Apparently you got one that was not defective. A comment regarding the height. It is true the Comfort height and ADA height toilets are becoming quite popular, but for those like yourself that a shorter than average, then the old standard height is probably a better fit. You seem to have the idea that only AS makes the 15" standard height bowl. This is not true. Most, if not all manufacturers still produce the standard height. It's not too likely that there will be much increase in availability however. It's a simple fact of supply and demand. There just isn't a big demand for the shorter bowls.
