Description

Sink with storage cabinet utilizing sink space}

The present invention relates to a sink having a storage cabinet utilizing a sink space.

In general, a sink consists of a sink for washing dishes and food, a drain hole for discharging water from the sink, a body on which cooking or objects can be placed, and a main body in which the lower part of the sink and the drain hole are accommodated. It can be.

However, the conventional sink has a problem in that it is difficult to store items as the lower part of the sink and the volleyball water are accommodated in the main body.
