From the website your floorplan has 93 gallons of grey water. If you have two gray tank valves (1 for galley or kitchen, the other for the shower/lavatory or bath), this is typically split evenly between two tanks. Therefore the galley tank is about 46.5 gallons and the bath would be the same size of 46.5 gallons or 93 gallons total.
