For example, when the horizontal length of the top plate is 200 cm, two assembled cabinets having doors of 50 cm width and one assembly cabinet having doors of 100 cm width may be accommodated.

According to the sink manufacturing method according to the embodiment of the present invention described above, it is possible to separate construction of the upper plate and the lower cabinet. In particular, since the sink construction can be completed only by accommodating the lower cabinet in the form of a mass-produced finished product after the construction of the top plate, the construction is simple, the construction period is shortened, and the construction cost can be reduced.

Those of ordinary skill in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims described below rather than the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. should be interpreted
