The double tank is the most popular type on the market at present, and it is also very practical. This type of stainless steel basin sink is mostly sub-basin (that is, one large and one small). The main basin + auxiliary basin can be combined, and both sides can be started at the same time. The one I bought myself is a double tank. When washing dishes, one side is used for washing and the other side is used for flushing. When washing vegetables, another basin is equipped with a draining basket to drain the water, so that water will not accumulate on the countertop.
Double tanks are suitable for kitchens with large countertops, especially for families with dishwashers and families with a small population. It is better to choose double basin stainless steel sinks.
