There are generally three standard sizes of kitchen sinks, single sink, double sink, and triple sink. Of course, the sizes of different models are also different, but generally speaking, the size of stainless steel sinks is relatively standard. The general sizes are 60*45cm and 50*40cm for single sinks, which are relatively small; the sizes of double sinks are generally 88*48cm and 81*47cm is more common; three-slot ones are generally 97*48cm and 103*50cm are more common.
