- The basic triangle is considered as the most efficient layout design for a commercial kitchen. This means the stove, sink, and the refrigerator should be arranged in the triangular shape. This is done so that these equipments are accessible from each other. These are the three most vital elements of the kitchen, and so there must be a straight path connecting these. When the corners of this triangle are brought together, it should add up to approximately ten to twenty-five feet. Less than this measurement will be too small for more than one or two persons to move throughout the kitchen comfortably and more than twenty-five feet will also be too big. Once the triangle is created with the premium quality refrigerator, sink, and stove, one can begin to add the other equipments like the microwave, the dishwasher, the upright freezer, etc. that are needed for different purposes in an industrial kitchen.
