Looks like it's time to replace the worn hole in the counter called the sink. First, think about the boundaries of your space. You don't want to buy anything that's too big for your space. So it looks like you have a pool in your kitchen.
Now that you know what size sink you need by measuring your kitchen and family, let's talk about getting it done. The most common are stainless steel sinks. This sink is tested and true, comes in a wide variety of prices, shapes and sizes. You can purchase good quality kitchen sinks online via kralsu.

Cast iron sinks are the way all sinks are made when my grammar is whipped. They have a slightly more limited shape than their versatile cousin, stainless steel, but they have something stainless steel lacks, which is color. Another consideration for a cast iron sink is weight.
The type of cast iron sink you choose for installation (commissioning or installation) will determine whether any special installation hardware is required. If this doesn't upset you and all you want to do is buy one more sink in your life, cast iron is for you.
The new kid on the block is a composite sink. More and more home owners are choosing composite kitchen sinks. They look great and granite composites feel soft. Prices are comparable to stainless steel and look more modern. This is the type of sink you will find in a modern New York loft apartment or your wealthy cousin's home.
