The sink dimension is a crucial factor when selecting a sink for the kitchen. You should first consider your kitchen’s space availability and the size of the countertop. Make sure you have the right size cabinet to install it. You may need to make some adjustments to the cabinet if you plan to replace your existing sink. However, you should go for a model that is large enough to accommodate your pots and pans. For a small household, a deeper 24-inch sink is enough to handle most of the washing needs. But if you have a larger family, you should choose a 33-inch sink.
