Cabinet space and the depth and width of the cabinet determine the size of the sink. In the process of choosing and purchasing, we must choose the appropriate size according to the actual situation. Particular attention should be paid to the fact that sufficient sizes should be reserved around the table surface for the installation of the flume to ensure the bearing capacity of the table surface and sufficient operating area. In addition, because the tableware we usually use is thicker and larger, the depth of the sink also needs to be fully considered, 180-200 mm is more appropriate. Generally speaking, different types of flume should have a general understanding, so as to facilitate the choice according to different room space and living habits.
