There are many things to consider when installing a kitchen sink. You want a material that looks attractive, is easy to maintain, and will last a long time. Kitchen sinks are available in a wide range of colots and materials that are very durable. What you will use the sink for and your own personal taste will help you decide with material to choose.
Stainless steel is the most popular choice for kitchen sinks. They're attractive, easy to clean, and they don't stain or rust. They aren't as expensive as other options, and it's easy to choose one that meets your qualifications. Thicker gauge stainless steel sinks resist dents and water spots. Most people choose 18 or 16 gauge. The lower the gauge number, the thicker the metal is.
A sink that's been around for a long time is one made of cast iron covered with a porcelain surface. They come in many colours, and they're durable and heavy. They are so heavy they may be hard to install, but they resist damage and retain heat. The porcelain surface is smooth and easy to clean.
Soapstone is a light grey stone that gets darker as it ages. Many people like the character they get with a sink that continually changes colour. Sinks made of soapstone are smooth, easy to care for, and they retain heat. Fireclay, or ceramic kitchen sinks, have hard, smooth surfaces that don't discolour, fade, or rust. Vitreous china sinks come in many colours. They're durable and easy to clean, but you can't pour boiling water in them and dropping heavy objects in them can damage them.
Granite composite, which is a synthetic material made under different brand names, is sold at Home Depot, Lowe's, and plumbing supply stores. They are scratch, chip, and heat resistant. Because they have the same colour throughout the sink, if they do somehow get scratched, it won't be noticeable. They're only available in a few colours.
Copper sinks are becoming more popular because of their health benefits. They're more sanitary than other sinks because bacteria and viruses can only live on them for a few hours. They have what is called a living finish, which means they change in colour and texture over time. The're easily cleaned by washing with gentle soap, water, and a nonabrasive sponge. Copper sinks should be dried when you use them to avoid water spots, and you should leave water running when you work with acidic foods that can damage the antibacterial finish. Copper sinks are durable and they don't tarnish or rust.
