that would do. each typical bathroom could accomodate several. Likely as many as the stalls and sinks in it which is usually like 3-5 and since you have men/womens you would end up with half a dozen to a dozen bathrooms in the same footprint. Might have to put a small hall because of the depth of the bathrooms but it just needs to be wide enough for wheelchairs and for the doors to open.
maybe systems. my work tends to be getting one or more systems to do something a business wants.
