Before you begin looking around for a new sink, call the professional sink installers in Westmont because they can help you identify the size of the sink that fits your purpose and the size of your kitchen. Single-bowl models come at 22 x 24 inches and they are perfect for kitchens that are less than 150 sq ft. If your kitchen is much bigger, multi-bowl models offer added functionality as they give you separate areas for rinsing and washing. These sinks usually have depths that are equal on both sides. The costs of the units increase up to ten percent for differing bowl depths.
