The present invention relates to a sink bowl including a drain unit. The sink bowl comprises a sink bowl (1) having a drain hole (11) formed on the floor and having a combination step (12) formed along a border of the drain hole (11); a drain unit (20) having a storage space formed inside by having an upper part opened, having a drain hole (21) connected to a brain pipe by penetrating an inner floor, and having a combination step (22) formed along an upper border by corresponding to the combination step (12); and a ring-shaped rubber packing (30) placed between combination steps (12,22). A plurality of protrusions (S) are protruding from one selected from the combination steps (12,22), and the sink bowl (10) and the drain unit (20) make contact with each other through the protrusions (S) and are pressurized and welded to fix the combination steps (12,22). Therefore, the present invention is capable of eliminating the inconvenience of assembly between the drain unit and the sink bowl, preventing foreign substances in a combination part of the drain unit with the sink bowl, and preventing leakage between the sink bowl and the drain unit.
