The perfect complement to that commercial kitchen faucet or any type of faucet you just purchased is a brand new kitchen sink. Buying an undermount kitchen sink is easier than it sounds, and even for those without a new faucet or faucet water filter, upgrading your sink to one of the better ones on this list will yield immediate results. The biggest decision you need to make after reading this list is whether you prefer granite or stainless steel — the specifics of which are outlined in this mini guide.
Since everyone has their own personal preference, the guide is meant to impartially outline the pros and cons of each model. Because of the superior construction of the sinks, the available options are all relatively high-priced. This is a reflection of the craftsmanship and quality of the materials rather than overpricing.
They are priced based on the weight and quality of the materials, which each company has 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.

Undermount Kitchen Sink Buying Guide
Top Brands: Kraus and Blanco
The two companies have a very different history, mostly because Blanco has German roots going back as far as 85 years while the USA company Kraus 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 with added modern touches. Blanco has a slight edge with styling and continues to produce some of the most inspirational products on the market. Customers should definitely keep their eye 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, answered by few. The best way to break it down is to compare the strengths and weaknesses of both. Starting with which is more scratch resistant, granite wins by a landslide. Grids were introduced a while back to minimize scratches on stainless steel sinks, but there will still always be the issue of scratches and nicks here and there.
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 compare to granite. Where stainless steel wins is with its many configuration options and colors, many of which aren’t available to granite sink makers.
There are twice as many manufacturers of stainless steel sinks than granite, giving customers endless project options without limitations. To sum up, for durability you want a granite sink, but for customization you want a stainless steel sink.
A great kitchen sink will always start at a medium price point, with lower priced items lacking in quality and structure. It is rare to get a kitchen sink worth anything if it is low priced, so beware of companies offering low priced alternatives as the materials are likely not up to par of those mentioned on this list. Also, beware of overpriced sinks that are not from reputable companies as the lifetime warranty is the most important aspect for a consumer that has an issue or complaint.
