How to Choose the Best Undermount Kitchen Sink – Buyer’s Guide

When looking for a new undemount sink, you want to be sure that you’re getting value for your money.

Most importantly, you have to pick a sink that can meet your needs. Here are the most important considerations to make before you spend your cash.


This one goes without saying, right? Yes. You’re better off with an undermount sink that is large enough to allow you to clean your dishes and fill your pots comfortably.

Also, it has to fit in your kitchen’s cabinet. In fact, your cabinet plays an essential role in determining how big or small your sink will be. A good model should be broad enough to handle your pans and pots.

If you have a small kitchen, say 150 square feet, choose a standard unit with dimensions of 22 by 24 inches.

For a larger kitchen, consider picking a sink with two or three bowls. Don’t forget to check the depth.


Most undermount sinks are made using stainless steel, with the thickness measurements in gauge. In simple terms, the lower the gauge, the thicker the steel.

By extension, this translates into extended durability. Of course, you’ll get more value if you choose a lower gauge.

That way, you will reduce the dents and the dings. We recommend that you stick to 18-gauge and below.

Heat Resistance

More often than not you will need to place hot pots and pans on your sink. You, therefore, need to invest in a model that can handle the heat.

All the units we’ve reviewed above offer reasonable heat resistance.

A resilient sink will not last for long but will also maintain a clean look for years. While it may be difficult to tell if a specific model is heat resistant or not, you can always read user reviews to get a glimpse of what the sink you intend to purchase has to offer.

Noise Control

You don’t want a sink that will keep making noise every time you’re cleaning silverware, do you? Besides, water running down your faucet can generate unnecessary noise.

Sure, the gauge of your sink’s steel can have an impact on the level of noise but you shouldn’t by a unit that doesn’t have a feature to control the level of sound.

Choose a sink with sound pads and insulating foam to keep noise at bay. Some, such as the Kraus Standart PRO use special technology to keep noise levels as low as possible.

The Design

The best undermount kitchen sink should be attractive, modern and stylish. You want a model that can complement how your kitchen looks and blend in perfectly with the rest of the decor.

If you’re buying a stainless steel sink, you need to look beyond the glossy or polished finish. Indeed this sparkle will add shine to your kitchen, but it is tough to maintain.

Remember, the finish will get soiled by smudge and fingerprints. For easy maintenance, consider satin or brushed finish.

These hide water spots and scratches in comparison to their stainless steel counterparts.

Also, pick a sink that is smudge proof and one that is easy to clean. You want to know that you can pour wine or ice on your sink without affecting its strength.

On top of that, invest in a model that is rust and corrosion resistant.


When buying any kitchen appliance, you can only get what you can afford. The case, however, is a little bit different with undemount kitchen sinks.

The truth is; you will hardly find a model that can handle the beatings of everyday use on the cheap.

If you want something that will last you long enough, consider investing a high-end model. It is essential to note that high-end here doesn’t mean splashing thousands of dollars for a best kitchen sink.

The sinks we’ve reviewed above will offer excellent usability and function without somersaulting past your budget.

One more thing; ensure that the sink you choose meets all the set safety standards. In other words, the outer layer should be lead and BPA fee with certification from bodies such as ANSI, ISO, and the likes.

And of course, you’re better off knowing what previous owners think of the sink so be sure to read a couple positive and negative user feedback.
