Buying Guide For The Best Undermount Stainless Steel Sink

When buying any sink, its size is the primary consideration. However, since the main topic of this article is based on 28 and 30 inch sinks, we won’t discuss size too much.

Colors And Finishes

Try to choose styles and colors that are good at hiding marks and scratches.

But their main function is to look good. Our preferred finish is gunmetal black. However, different versions of stainless steel finishes are also good.


After size, the material of construction is the most important thing in any sink. Most undercounter sinks are made of stainless steel. However, they can also be made of the following materials instead of stainless steel

  • Composite granite
  • Cast iron
  • Clay
  • Stone

Now, there are many things to know when buying a stainless steel kitchen sink. Generally speaking, all manufacturers use T-304 grade steel or 304 type steel. You may also see numbers such as 18/0, 18/8 and 18/10. These are the ratios of chromium and nickel content of the steel. Chromium and nickel are used to maintain the rust resistance and gloss of the sink. The first number represents the 18% chromium content. The second number tells you the nickel content. 8% and 10% nickel are almost the same. You do not need to differentiate between them. However, 18/0 means that there is a minimum nickel content. Therefore, the shine of the sink will not be long lasting. There are some sinks with a 13/0 ratio. However, you should avoid them. They are very inexpensive materials for the home kitchen.

Sink Thickness (Gauge Measurement)

A gauge is a measurement of the thickness of a stainless steel kitchen sink. The smaller the number, the thicker the steel. And the thicker it is, the less likely it is to show dents. Generally, you’ll find stainless steel sinks from 18 gauge to 23 gauge.


However, there are extremes on both sides. But as we showed in the review, you can get a 16 gauge sink for almost the same price. So, why choose less when you can have more. Here is a comparison table of sizes vs. mm-

Sound Guard

The high quality sink includes a layer of sound absorbing and vibration dampening material, which reduces dishwashing and friction noise to 10% or less.

Other Small Features

Drainage grooves allow for easy drainage. If your sink has proper recesses, you will have less mess to deal with. The slope should be such a level that the goblet can stand, but the water should flow. A grid at the bottom may reduce its importance. The finish should be able to withstand the extreme temperatures at both ends. It should also be able to resist scratches and marks.


A sink without accessories is certainly budget, one that is very low priced. However, if you are paying a high price for your sink, you should have most, if not all, of the following accessories.

  • Bottom rinse screen
  • Basket strainer
  • Drain strainer cover
  • Scratch protector
  • Sponge holder
  • Cutting board
  • Folding rack
  • Strainer
  • Drainer components

Some brands even include special items such as aprons, oven mitts, oven gloves and towels. For installation, the manufacturer may also give you the following things –

  • Cutout templates
  • Mounting clips
  • Installation guides
  • Mounting hardware

You should have most, if not all, of this stuff.

Frequently Asked Questions

Here are some questions that only curious buyers will have. All the generic stuff is described elsewhere in the article.

  1. What is the range of chromium and nickel content?

A: In the US, the chromium content range is 18%-20%. More importantly, the range for nickel content is 8-10%. So when they say it is an 18/10, it means that chromium is in the 18-20% range and nickel is in the 8%-10% range.

  1. which is the best style of sink?

A: According to our understanding, large workstation sinks are the best choice. However, you need to have enough space. Go ahead and use a deep basin.

  1. If I buy one without accessories, will the discount be the same as the cost of the accessories?

A: I don’t think this is a good idea. If you have to buy all the accessories, it will cost more to buy the accessories separately. However, if you don’t need all the accessories, you may save some money.


Wow, you’re still here. You must really be serious about your kitchen. Who else would read a boring paper just to discover the best 28 or 30 inches under-counter kitchen sink?
