I need to replace the 2 old toilets. I measured the rough in as seen below. Seems that I need to buy the 14 inch rough in toilets (which is hard, because only few models are available at Home Depot and Lowes, since this is a non-standard size). Am I doing it right? Any advice on the model? I wanted Toto, but Toto are all for the standard 12 inch rough in.
