Kraus KHU100-30 Kitchen Sink

  • 3 piece basket strainer set
  • T304 stainless steel in TRU16 real 16 gauge
  • NoiseDefend soundproofing technology
  • Installation Method: Undermount

This is a commercial grade single-bowl undermount kitchen sink. It is large enough to handle even the largest pots and pans and is super insulated for minimal noise. It is made out of stainless steel which is a top choice for food prep areas because it is very easy to clean and is a durable metal. It is resistant to spots, fingerprints, and scratches. Unlike porcelain or stone, stainless steel will not crack or chip. To maintain the appearance of the finish, all you need to do is simply wipe down the surface with a cloth, no chemicals or scrubbing required. It has a satin finish which is easier to maintain than high-polish finishes and matches most household appliances.

The only downside of stainless steel is that when it is used in a sink of this size the large chamber can create an echoing environment for the sound of the water and dishes hitting the wall of the sink. Kraus has solved this issue by double insulating this commercial undermount sink with both a nontoxic SoundGuard coating which stops sound causing vibrations, and NoiseDefend padding which covers over 80% of the sinks underside to cushion noises for maximum soundproofing.

It is made by a reputable manufacturer who only uses top quality materials in the construction of their sinks and home appliances. Included with your purchase is a limited lifetime warranty that protects your purchase against parts defects and finish defects as well as shipping damage. The installation process is super easy, and once it’s done the performance of the sink is guaranteed for a lifetime. It comes with all the necessary hardware, as well as a few extra accessories.

It’s big enough to clean large pots and pans and has two drains so two people could use the sink at once. Kraus only uses the highest quality materials in the construction of their sinks, such as the TRU16 stainless steel used in this model. The stainless steel is highly resistant to corrosion and rust.

The bottom of the large double basin sink is optimized to prevent any sort of standing water and maximizes drainage. It’s super easy to keep this sink clean and the construction is made for both beauty and efficiency, with curved corners for easier cleaning. You can run a cloth cleanly around the rim of the bowl without any sort of crevices for dirt, food, and germs to hide in. The round apron front design has a softly exuding curve and crisp geometric lines that cleanly integrate with your kitchen counters. An apron sink such as this one is a unique alternative to traditional sink models and will easily become the focal point of your kitchen.

It has two bowls that you can use for different purposes. You can use one side of the sink for drying, which saves counter space and is also more hygienic than putting a dish dryer on the counter. You can also save water by only filling up half the sink when you need a basin full of water. There are lots of benefits to having a double bowl sink instead of a single bowl, however, it does mean there is less room for cleaning big dishes. It makes up for this with an extended size, taking up slightly more counter space than a single bowl model from the same manufacturer.

The Benefits of Having An Undermount Kitchen Sink

Best Undermount Kitchen Sink ReviewsUndermount kitchen sinks are popular in both commercial and home kitchen settings for a variety of reasons. They are aesthetically pleasing as well as having many practical benefits. Here are a few of the ways a high quality undermount kitchen sink can improve your kitchen experience.

One of the top reasons why people decide to go with an undermount kitchen sink for their home is because of its modern, seamless appearance. The sink sits below to counter, with no lip or raised edge that interrupts the flow of the counter. This makes the lines in kitchen clean and crisp for an aesthetically pleasing, contemporary, and modern feel.

The outer rim of a sink can become a breeding ground for mildew, mold, and germs. The clean, sleek lines of an undermount sink makes it easier to clean because there are no crevices where dirt can hide.

The outer lip of the sink takes up about two or three inches at least on an average drop-in sink, and with a new undermount kitchen sink you will be saving that space. It may not seem like a big difference, but those couple of inches of space can be utilized for storing a soap dispenser, water filter, or more.

Things To Consider When Buying An Undermount Kitchen Sink

Best Undermount Kitchen Sink ReviewsSo you’ve decided that an undermount kitchen sink is right for you. What’s next? There are lots of undermount kitchen sinks on the market in a variety of styles, shapes, finishes, and each with their own unique features. To decide which one is right for you, there are a variety of things to consider. This handy list can help you determine what features and functions are most essential to you.

The size of the sink is very important. You will want to go with a sink that is big enough to handle all of your kitchen needs including cleaning and cooking. You also will need to make sure that the sink is small enough to fit your kitchen cabinet properly. Here’s how to know:

Think about the biggest pot or pan that you own. Will it fit in this sink? If not, then move on. You will need a sink that is big enough to handle all of your kitchen cleaning tasks, so don’t cut corners on size just to save a few bucks. If you don’t use any large pots or pans, you maybe can consider a small model of undermount kitchen sink, but for most homes ample space is required to efficiently clean pots and pans and one of the best things about undermount kitchen sinks is their ability to make the most of a space.

This point is an absolute must. Unless you plan on going through a messy, expensive remodeling process, you will want to be sure that the sink you choose fits with your existing kitchen cabinet. A large sink will require a large cabinet and vise versa. You may be able to edit an existing cabinet for a larger sink, but it is not recommended as it may compromise the integrity of the structure. Measure your sink multiple times for accuracy while taking measurements.

When talking about undermount kitchen sinks, the gauge thickness refers to the thickness of the metal used in construction of the sink. To understand what the gauge number represents you need to know that the lower the number, the higher the thickness. So a thinner sink would be 22-23 gauge, and a higher quality sink would be 18 to 19 gauge.

Why is Gauge Important?

Different materials have different resistances to heat. Metal is highly conductive and can easily heat up when exposed to hot water. A sink with a higher heat resistant is preferable because not only can hot metal or porcelain cause burns, but a lack of resistance to extreme temperatures can make the sink more susceptible to damage. Extreme cold or heat can crack, melt, or bend the sink.

When the sink heats and cools, it can cause condensation to build on and under the sink. This condensation and moisture can be the cause of all sorts of damage. Moisture can corrode through materials, even high-quality ones, and cause health-threatening mold and mildew. The moisture can also freeze over during cold months causing damage to the structure of the sink and the piping.

When dishes and other objects hit the side of the sink it can make obnoxious clanging noises especially with certain kinds of metal. Using a different kind of material can help to soften the noise and there are also several noise reduction features available. These techniques can even extend the lifetime of the sink because they prevent condensation from building due to temperature changes which can cause damage and corrosion over time.

Best Undermount Kitchen Sink ReviewsDenser materials such as porcelain or quartz are much more effective at absorbing noise than thin metal materials. A higher gauge, or thickness, of metal will also be more effective at reducing noise. The material used is the number one indicator of how much noise the sink naturally makes, but any material can be sound-proofed with the correct additions.

Using rubber padding on the bottom of the sink can help create a soundproof barrier to absorb the noise of an impact. The padding may also extend to the sides of the sink as well to prevent noise from water splashing up. This type of noise insulation is great for larger sinks where the large walls can bounce back more sound.

There are certain kinds of coatings that can be applied to the bottom and sides of a sink to help dampen the noise. These spray on coatings help to neutralize the vibrations which cause noise. A spray-on coating is less effective than other methods, reducing but not eliminating noise. It can be combined with padding and other techniques.

The design of the sink refers to both the appearance and the function. Different styles of sinks can differ in features and performance as well. All undermount sinks are made to be installed underneath the counter, instead of dropped in on top, including a type of sink called the farmhouse sink. A traditional undermount sink is made to seamlessly integrate with the counter, and not be seen. A farmhouse sink on the other hand is still undermounted, but it becomes the focal point of the kitchen because the front of it shows through. Undermount sinks also come in a variety of materials/colors and can be single or double-bowled.

Granite is a material made out of combined resin and stone for a classic marbled appearance. Granite has become a less popular material for sinks in recent years as consumers and manufacturers have shifted towards cheaper and faster methods, but granite is one of the most durable and long-lasting materials for a sink construction.

It also has a stylish, luxurious, and classic appearance. It has a far more unique look than a metal or porcelain sink. It has the look of a stone sink, but is more affordable. Sinks can be made out of pure granite or a combination of granite and quartz/other components.

Cons:

Best Undermount Kitchen Sink ReviewsStainless steel is a top choice for surfaces in both food prep and health care environments because it is one of the most hygienic metals. It is also very resistant to fingerprints, spotting, and damage. Stainless steel is a durable, heavy metal that is much stronger than lighter metals. The lower the number of gauge, the thicker the metal and the more durable construction.

For modern homes, stainless steel is a top choice. It is very affordable and there are stainless steel sinks of all shapes and sizes. The finish of a stainless steel sink can be polished for a reflective, mirror-like appearance or brushed for a soft-matte, homier look.

Pros:

Cons:

Quartz, like granite, is another unique choice for kitchen sinks that stands out from the traditional stainless steel and chrome. Quartz sinks are made out of a composite of resin and quartz stone, for one of the most durable and long-lasting sink materials. Quartz composite sinks have the look of real stone, but with a lower price.

Cons:

You may also hear porcelain described as vitreous china or ceramic. Porcelain sinks are beautiful and durable. They have a beautiful smooth white appearance and can come in other colors as well. It holds up well over time, and can be combined with other materials for an even more durable construction.

Cons:

As with anything in life, the cheapest isn’t always the best. On the flip side, the more expensive may not be the best either, although price usually does indicate quality. The price of the sink largely depends on the material. Real stone, granite, and quartz sinks are pricier than stainless steel, but stainless steel is easier to maintain. In addition to the materials, the price may reflect whether or not installation is included, delivery costs, and warranties.

Most reputable companies include a free factory warranty with the purchase of their products. A factory warranty is a guarantee from the manufacturer that they will cover the costs of any sort of product defects, and replace the product if necessary. The warranty will often all include the finish and any shipping damages. Many of the products reviewed in this guide come with a limited lifetime warranty from the manufacturer which guarantees excellent performance of the product for the lifetime of the kitchen.

You should always contact the customer service department of the manufacturer when buying your sink to find out more about your warranty options. Reputable manufacturers will have a friendly and highly trained team of customer service representatives available to answer questions, at least during regular office hours.

How To Measure For Installation

Best Undermount Kitchen Sink ReviewsUsing a high-quality and accurate tape measurer you should determine the measurements of the cabinet where you plan on installing the sink. You need to measure the length and width of the space as well as the depth. If the sink is too big for the cabinet, it may be altered, but it’s not recommended as this can compromise the structure of the cabinet and could make the cabinet’s warranty void. Most sink manufacturers will share the recommended cabinet size in the product listings and descriptions.

Conclusion

Undermount sinks are a stylish solution to high capacity cleaning in your kitchen. They come in a variety of shapes, sizes, and colors. The materials used and the size of the sink are the main things that affect the price of the sink, and just because it’s the cheapest or most expensive doesn’t mean that it’s the best. They each have unique qualities, so it’s important to compare and contrast undermount sinks to find which one is right for you.

Undermount sinks can be installed into the counter for a seamless appearance that doesn’t interrupt the flow of the kitchen or they can be an apron, or farmhouse style sink where the front of the sink shows for a stunning centerpiece. In this buying guide we have given an overview of some of the best undermount and farmhouse style kitchen sinks that are currently available on the market. Here is a summary of what we have learned.

The Most Important Factors to Consider Are:

  1. Size — undermount sinks can be both very small and very large. They are very versatile.
  2. Gauge Thickness — the lower the number, the higher the thickness. Thick is better.
  3. Double Or Single-Bowl — single bowls give more room while double bowls can save more water.
  4. Temperature Resistance — extreme heat and cold can damage sinks that are not resistant to temperature changes.
  5. Materials — the material of the sink affects every other factor on this list and one more, the appearance.
    6
  6. Warranty — a quality sink should come with a limited warranty from the manufacturer.
  7. Price — the price of an undermount sink can vary greatly depending on the materials used.
  8. Noise — large sinks are noisier than small ones. Choose a sink that utilizes multiple sound-proofing strategies or is made out of a naturally soundproof material like stone.

Benefits of an Undermount Sink

  1. Seamless Lines — the design of the sink is that it sits below the counter, not interrupting the clean lines of the kitchen.
  2. Easy Cleaning — undermount sinks have less crevices than drop in sinks so there is less space for dirt and food to hide.
  3. Counter Space — undermount style sinks make the most of the counter space in your kitchen because they don’t have a lip or raised edge that sits on top of the counter.

Now that you know what an undermount sink is and what a farmhouse sink is, you are more equipped to make your decision regarding wheat features you may want. Choosing a material like granite or ceramic will give you more choices in color and appearance, whereas stainless steel is generally less expensive and is a super clean and durable metal for use in food prep environments.

Double-bowl sinks offer the benefit of dual purpose basins, where you can use one for washing and one for drying. Single-bowl sinks have more room on the inside for washing large pots and pans so they’re ideal for high-capacity kitchens. There are benefits to both. Another benefit of a single-bowl sink is that is can be installed in a small space or corner to maximize counter space.

Undermount kitchen sinks are a beautiful choice for a modern home and are very versatile. A high-quality undermount kitchen sink will be made out of top of the line materials, come with a free factory warranty, and should include everything necessary for installation. For the best results, trust a professional with the installation process.

Hopefully this buying guide has given you deeper insight into the world of undermount kitchen sinks, what the benefits are, and how you can get the most out of your purchase. With all of the different sizes, styles, and finishes, there is an undermount sink suitable for everyone. If you don’t fancy any of the sinks on this list, here are some more undermount kitchen sinks.
