From a vast variety of sinks diversifying in configuration, shape, and style; we have chosen this Kraus “KGU-413B ” model which is a single bowl, rectangular, and undermount (or drop-in) in style. The motive for selecting a sink with these characteristics is the ease of use. Going into details, regarding configuration, a single bowl sink always provides more space for working as opposed to sinks with more than one bowl. Concerning shape, a circular sink is inconvenient to use. And about style, an undermount or drop-in sink is more practical than a top mount and a farmhouse sink which is very heavy and more susceptible to deterioration because the front side (i.e. apron) is exposed.

Keeping in view this all, we have suggested this single bowl, rectangular sink at first. Even though the subsequent Kraus sink with double equal bowls (discussed below) has far more ratings than this one, the advantageous aspects compelled us to give flagship to this single bowl sink.

Returning to its design, it is available in two colors; black and gray. The size is reasonable and handily functional. With the dimensions of ‎30.47 x 17.09 x 8.66 inches, it can hold many utensils at a time. The deep cookers, large dishes, and jugs can accommodate because the depth is satisfactory. The dimensions of this sink are a little higher implying that it may not complement a small countertop.

Coming to the quality, the sink is subject to high strength and durability. [Herein we must mention that the upcoming Kraus sinks also have the same features when regarding the material. They just alter in physical characteristics whereas material facts are solely alike because all Kraus sinks have been made of the same material (i.e. granite composite)].

So, the material is resistant to scratches and dents. Its construction makes it invulnerable to temperature variations. Resultantly, it can stand a temperature up to 650°F which reflects that you can directly keep the cookware from the stove inside the sink. This is truly an incredible characteristic.

Moreover, you don’t need to be troubled with cleaning and maintenance because the stains can be scrubbed with proper clean-up. Also, the sink offers protection against any bacterial activity greatly around the drainage hole. This is also because the surface is slightly sloped towards the drainage hole to prevent stagnant water in the sink, stimulating odor. Notably, the pots are yet not likely to fall on this inclined angle.

This granite sink does not undergo rusting which is why it will not look dull earlier. Lastly, the sink has a quiet surface owing to producing less noise.

This is always beneficial to have a grid or rack for the sink as it not only protects the sink surface against scratches but also dries the washed pots.

One more thing, if you install this sink in undermount style, cleaning becomes more effortless. But, if installed in top-mount style, there won’t be a thorough cleaning because the outer rim acts as a barrier.

In the list of top mount granite composite kitchen sinks, this sink incorporates many similar features as previous Kraus sinks. Like them, this also governs the identical material properties. Therefore, it is greatly reluctant to prevail alteration due to temperature shifts, high loads, and continuous water exposure that can oversee corrosion.

Furthermore, scrapes and cracks don’t prevail earlier by the placement of crockery and cutlery.

The sink’s slightly inclined surface towards the strainer helps keep the sink free from microbial growth because water keeps on flowing under the drain.

Another similar feature is the dual mounting. Though, as demonstrated before, undermount installation is better than the drop-in or top-mount. Although the latter is easy, the long-term ease lies in the former on the account of cleaning and maintenance.

How to Choose the Best Granite Composite Sink? Buying Guide

Being a central point of a kitchen, the sink should be owned after ensuring paramount key aspects. Having a sink with lush color that complements the countertop is not enough because such a selection has the potential to prove worthless over time. Always ponder over the following features for the best granite composite sinks for kitchen if you are truly serious about money consumption. In the market, a plethora of sinks are available differing in configuration, shape, mounting style, material strength, noise reduction ability, and cost. They all claim to be the best. But, you need to be aware of the pros and cons of these designs to get a better idea of the sink which meets your requirements the most. 


In the wake of consumers’ needs and variety, sinks are made in different configurations i.e. single bowl and double bowl.

Single bowl granite composite sinks are the most advantageous to use for they offer ample space for comfortable washing. Also, they can hold wide cookers, large dishes, and containers.

In the above write-up, we have suggested three single bowl sinks that outrank the rest of the two double bowl sinks.

Double bowl granite composite sinks although enable multi-functioning, yet they are less helpful to fit large pots inside. There are further two types of double bowl sinks such as two equal bowls and two unequal bowls. Unequal bowls are somehow satisfactory because they at least provide more capacity in one bowl than the other for washing.

Sinks with even more than two bowls are also available but in granite composite material, they are hard to find. Usually, sinks with one or two bowls are available. Though, there is another type too which is a granite sink with a drainboard.

A granite composite sink with a drainboard is such a design in which a drainboard is attached to the sink to keep washed pots there for moisture release. The water does not seep the board into the cabinetry, rather it is plain without holes or grid. All the water can be passed to the sink. Such a sink is quite useful for butcher block countertops where wood is susceptible to water exposure. The lesser the exposure is, the more will be the life of the wooden countertop. Continuing, this sink is truly helpful but it requires more than average space. If you are concerned with drying, sink racks can be used.

Regarding availability, a granite sink with a drainboard is also the least common which is why you will rarely find this in the marketplace.


It has been identified that rectangular sinks always substantiate to be more convenient than round. You will find most of the best composite sinks in a rectangular shape. However, in some of such sinks; a rectangular shape is further designed to make it more contemporary. But it just devours the space which could otherwise enhance the sink area. So having a simple rectangular shaped sink is always emphasized. Also, the circular sinks in granite composite material are as unusual as granite sinks with drainboards.


The easiest go installation is undermount. Upkeep becomes so simple that you can wipe off the area around the sink in a very simple manner. Nonetheless, such a mounting is not as simple as a top mount.

Top-mount or Drop-in style becomes a barrier for water to go to sink straight while cleaning the counter every time. This is because the outer rim of the sink is mounted not below the counter but above.

Next, there is a probability of the sink’s dispositioning with time ending up in its loosening and movement. The upshot is the gaps’ creation which prompts water seepage in the cabinetry. To avoid this, you can though use a caulking material too, yet these conditions are not favorable.

However, such an installation is easy because you just need to put the sink in the already “cut” area of the countertop.

In the first section, we have presented four top mount composite kitchen sinks that can be installed in undermount style as well.

Farmhouse or apron-style sinks are heavy and should be used only if proper maintenance can be carried out. Being heavy their installation is also challenging. Plus, they need thick support due to being bulky such as the above-recommended granite farmhouse sink that has a substantial weight. Notably, this fact makes them less recommendable for wooden countertops.

Material Quality

In the best composite kitchen sink, this element is determined by assuring the material’s resistance against denting, bending, scratches, temperature, rusting, and bacterial growth.

Granite sinks do not usually undergo corrosion even after recurrent water exposure.

Continuing, if the color is black, the granite sink can be prone to visible scratches because stains and chips are more apparent on dark surfaces. Nevertheless, its hard construction makes it sturdy enough to tolerate shocks and high loads whilst averting bending and denting.

Regarding temperature vitality, the Kraus and Ruvati sink greatly sustain temperature up to 650°F. This factor is integral because many times we place hot pots in the sink which can leave marks and fade the color. So, the best composite sinks should be able to stay ineffective.

Aside from that, bacterial growth prevention is what we also need to be concerned about. It has been observed that around the drainage area as well as the outer rim (in the top mount sink), the bacteria grow and cause odor. This is dominant in the sinks where the surface is not inclined to the drainage, encouraging stagnant water conditions and eventually microbial growth. In the case of the outer rim, some food particles get stabbed in the rim due to improper cleaning. Since they are organic, their degradation causes odor over time.

Because of all these conditions, an undermount style is better than a top monster structure. 

Sound Absorption

Almost all the sinks produce noise up to some extent even if they are made of very quiet material until mats are used. The granite composite sinks have a sturdy structure so they do also produce noise.

Conversely, the thickness of the material matters a lot in this regard. This is observable in the case of stainless steel sinks that produce substantial noise if the thickness is less. Comparatively, granite sinks are less noisy than many other sinks including steel.


Being made of natural stone, granite sinks are relatively more costly than many conventional sinks such as stainless steel sinks.

On average, the best composite kitchen sink with acceptable features can be availed at a price of around 250 to 350$. It is better to consider reputed brands because they take responsibility to repair as well as change the product in case needed.

Best Granite Composite Sink Brands

Not all the sink manufacturing brands produce granite sinks too. Even among the popular ones, you will find a few only whose product quality is guaranteed.

Following this, Kraus, Ruvati, Blanco, Delta Faucet, and Frankle are the common granite composite sink manufacturing entities.

The best of all is the “Kraus” that is credible in terms of quality as well as affordability. The “Ruvati” sells quite expensive sinks nonetheless quality overshadows their cost. The rest of the brands are not very popular so their quality cannot be estimated. Markedly, they are the competencies in the market for sinks of other materials, specifically stainless steel.


The supreme selection of the best composite sinks has accentuated that none of the products is inferior rather they all are fully useful for specific purposes. However, the best sink as already stated is the one that has a wide capacity and easy upkeep. Upkeep reflects material’s quality and simple mounting whereas capacity encompasses dimensions, shape, and configuration.

Experience shows that single bowl rectangular sinks with undermount structures are the most practical and easy to maintain plus clean. In this view, the Kraus KGU-413B sink stands out among all other sinks. Also, it is affordable. Even though you will find Kraus KGD-433B as the best-rated product, its double bowl structure made us mention it second because it provides fewer working areas than the former sink. Nonetheless, it is also a budget-friendly sink.

Aside from them, if you are interested in a farmhouse sink, the Ruvati RVG1533WH sink can be considered. Its features make it one of the best granite composite farmhouse sink.
