Dual sinks (double basin) is the standard model used in the kitchens. Kitchen sink like this allows multitasking, wash vegetables while soaking pans, for example. For a room that is somewhat limited, available with double sinks are not the same size, one smaller than the bath tub the other. The process of washing the food is usually performed in a smaller tub.
Triple sink (triple basin) with three sinks. Suitable if you have a large kitchen. Standard design consists of two large sink for washing cooking equipment, and a small sink in between, for washing food. Some designs come equipped with a cutting board and the corresponding seepage, so the sink that takes a lot of space was usable for more things than just washing.
