Best Undermount Kitchen Sinks

The perfect complement to that commercial kitchen faucet or any type of faucet you just purchased would be a brand new kitchen sink. Buying an undermount kitchen sink is an easier task than it sounds, and even for those without a new faucet or water filter for faucet, upgrading your sink with one of the better ones on this list will yield immediate results. The biggest question that will arise after going through the list is whether you prefer granite as the main material or stainless steel, a question that will be covered in a mini guide below.

Since everyone has their own personal preference, the guide is meant to break down the pros and cons without showing favoritism for either one. Because of the superior construction of the sinks, there are also no cheap or low priced options available. This is a good thing and shouldn’t be misinterpreted as sinks being too overpriced for the general public.

They are priced based on the weight and quality of the materials, which the companies have taken great care to put together. With the lifetime warranties available with each product consumers will have plenty of time to enjoy their new sink and all it has to offer. Here is the final list, with some great ones available from both Kraus and Blanco.

Kraus and Blanco

The two companies have a very different history from one another, mostly because Blanco has German roots going back as far as 85 years while the Kraus USA Company is new but has exploded onto the scene with some of the most unique European innovated designs the market has ever seen.

Both companies take themselves very seriously, and the best way to describe the difference between the two is the style and materials they use. Blanco excels at making traditional granite sinks that are second to none, while Kraus excels at creating reinforced durable steel sinks that add in a lot of modern touches. Blanco has a slight edge with styling and continues to produce some of the most inspirational products the market has ever seen. But customers should definitely keep their eyes on Kraus to see how they perform, and if they can continue to innovate.

Steel vs. Granite?

This is the big question that is asked by many, and answered by few. The best way to break it down is to compare the two with their strengths and weaknesses. Starting with which on is the most scratch resistant, granite wins by a landslide. Grids were introduced a while back to minimize scratches on stainless steel sinks, but there will always be the issue of their being scratches and nicks here and there if you go with stainless steel.

This of course means that granite is a lot more durable than even the strongest stainless steel, regardless of the company. Claims of incredibly strong steel is still valid, but does not lend itself to comparison of a granite sink. Where stainless steel becomes a winner is with its many configuration options and colors, many that aren’t available to granite sink makers.

There are double the amount of stainless steel makers than granite sink makers, giving customers endless project options rather than being limited to a smaller part of the market. So in short for durability you want a granite sink, but for customization you want a stainless steel sink.

Pricing Note

A great kitchen sink will always start at the medium price point, with average and barely good sinks landing in the low price range. It is rare to get a kitchen sink worth anything if it is low priced, so beware of companies offering low priced alternatives, as it may not be made from the same great materials that are offered on this list. Also beware of overpriced sinks that are not from reputable companies, as the lifetime warranty is the most important weapon you’ll have as a consumer when needing to make a complaint.

Summary

There is a lot of variety on this list when choosing between granite and stainless steel sinks, with a lot of great choices from both Kraus and Blanco. If buying a new sink and you don’t have a new kitchen faucet yet, then consider purchasing one as the market is booming and has a lot of interesting options to choose from. The biggest choice shouldn’t come down to price, but rather the value you get from the price. No matter what company you go with, as long as it fits your needs you’ll be in good hands.
