Best to refer to the bathroom interior elevations. One area of danger is the wall thickness behind the wc. If they play to put wainscoting, tile or stone on the wall, the toilet stub better be more than 12-1/2" off rough wall.

I prefer bringing the drain up through the floor. AAVs are legal here. Only thing I need to be concerned with is drawers.
illegal in Ky to bring thru floor,each fixture has to have individual vent

I have been roughing-in waste arms {lavs and kitchens} at 17" for years. I like that height. Water lines come out at 21"

I usually run hot water lines at 23" and cold at 19" this way I dont have to jump the cold over the hot to drop down for a toilet. Just point the cold 'tee' down with a 12" piece of pipe and BAM! my toilet stub out is at 6" off the floor.
