How We Assessed and Evaluated These Kitchen Sinks for Use in Areas with Hard Water
When it came down to selecting the kitchen sinks for hard water, we went with composite granite. Composite granite materials are made from a blending of around 80 percent solid granite stone, and usually an acrylic resin. This is then formed into the desired bowl shape. This material has excellent benefits for those living in hard water areas, as it offers strength, longevity, ease of maintenance, and resistance to scratching.
Strength and Design
Each of the kitchen sinks we looked at had to be known for its durability and strength. After all, the purchase of a new kitchen sink is an investment for your home, and as such should be expected to give you many years of service. We also selected a variety of shapes for you. For instance, you’ll notice that the Houzer model comes with the traditional 50/50 bowl split with a rectangle shape. While the Kraus comes with a rather modern 60/40 bowl split design with more curvy, organic contours which mimic water.
Ease of Cleaning
In the past, some composite granite sinks developed the reputation of being hard to clean. We wanted to make sure that we did not include any of those sinks in our list of the best kitchen sinks for preventing hard water. As such, we stayed with companies such as Blanco, which sought to overcome these concerns by developing their own, special type of composite material, in this case, Silgranit. Silgranit is actually 40 percent easier to clean than other surfaces due to the 7 industry patents taken out by Blanco. Also, consider our offering by Houzer. It is made with Microstop, which is an antibacterial agent.
Another past issue experienced by composite granite surfaces was that they could be easily damaged by heat or household cleaners. As this was the case, we looked for sinks that had no issue with household acids or alkalies, such as the Blanco Diamond model.
This is an added plus. After all, no one likes to be woken up by the clank and bang of dishes as they are being washed. Therefore, all of our 8 selections below have some sort of sound dampening quality, which we are sure other household members will appreciate.

Which type of kitchen sink is easiest to keep clean?n
A kitchen sink built in porcelain or ceramic with a single basin is easiest to keep clean. Because a single basin is easier to reach all of the surfaces rather than a double basin.
Why is my black quartz sink turning white?
There are a few reasons why your black quartz sink might be turning white.
