Great toilet, awesome flush and does not leave any, debris. It does come with standard 14inch roughin and we had to order special 16 inch from toto which cost $93, would have been nice if we could have specified when ordering, now have extra expensive part. Otherwise it is awesome, low profile, easy to clean and works well. make sure you attach the lid prior to setting down toilet and also make sure you assemble lid FULLY prior to closing it including snapping shut the plastic covers.
