Pantry sinks commonly in use are made of sheet copper; the higher grades are of enameled cast iron and of porcelain.
A very satisfactory pantry sink may be constructed by lining a wooden box, of proper dimensions, with white metal. The back and drain boards should also be lined with the same material. This work requires the services of a skilled workman, for it is a difficult matter to lay the metal smoothly and to finish the joints and seams so that they may be as nearly invisible as possible.
Many of the more pretentious residences now have a breakfast room in addition to the dining room, each being provided with its own special pantry sink.
The size of waste for the pantry sink should be 1 1/2 inch; the size of trap vent should also be 1 1/2 inch.
The pantry sink should be set so that the top of the sink is about 32 inches from the floor.
