Kitchen Sinks can come in Single Bowl, Double Bowl, Triple Bowls, and Farmhouse also known as Front Apron Sinks.  Kitchen Sinks are often made of Stainless Steel, Copper, Quartz Composite, and Fireclay (also known as ceramic or porcelain sink).  The most common Kitchen Sinks are either Single or Double Bowl.  Double Bowl Sinks are offered in different splits.  50/50 Sink meaning each side of the sink are equally split in size.  60/40 and even 70/30 Sinks are available with one side of the sink being bigger than others. 

Bathroom Sinks have some different styles from Kitchen Sinks.  Common Bathroom Sinks are made of Porcelain or known as Vitreous China.  Tempered Glass, Stone, and Copper are other types of Bathroom Sinks.  Stainless Steel (metal) can be used as a bathroom sink, but typically designed for Kitchen Sinks.   Bathroom Sinks are typically single bowl sinks.

                    • Gauge Measurement:
                      • Sink gauges are typically expressed as numbers, and the lower the number, the thicker the material. Common sink gauges for kitchen sinks range from 16 to 22, with 16-gauge being thicker than 22-gauge.
                    • Common Gauges for Kitchen Sinks:
                      • 16 Gauge: Thicker and more durable. Often used for high-end or luxury kitchen sinks.
                      • 18 Gauge: A good balance between durability and cost. Commonly used for residential kitchen sinks.
                      • 20 Gauge: Thinner and less expensive. Can be suitable for budget-friendly options but may be more susceptible to dents and noise.

                      Size and Configuration

                      • Measure the available space and choose a sink that fits the cabinet or countertop.
                      • Consider the number of bowls (single, double, triple) based on your preferences and kitchen habits.


                      • Determine your budget and explore options within that range. Remember that factors like material and gauge can influence the cost.
