I suspect the component you need really should have a piece removed that would interfere with the cabinets.   So to combine the best of both of Robert's ideas I would start with an accurate CAD profile drawn in elevation view and snap a face into that CAD profile and use the Revolve Object tool to rotate it 180°.  Then you have a solid that can be further refined using boolean operations.  Such as Solid Subtraction to cut out the unwanted underside.
