I Tested And Reviewed 10 Best Undermount Kitchen Sinks For Granite Countertops (2023)

After using JB weld epoxy to bond the anchors to the quartz surface, I found that they held up well even after 24 hours. To ensure that the clip doesn't break the studs away from the surface due to excessive leverage, I placed the clip on the bonding foot of the anchors. This helps to balance the pulling force away from the surface with the pressing force towards it, preventing any damage. However, it's important to be cautious and avoid getting epoxy on the anchor threads as it becomes difficult to screw in once the epoxy cures. In such cases, scraping off the epoxy from the threads is necessary.

These anchors are a great solution for under mount sink installation. It seems that some users may have failed with the product due to either using the wrong adhesive or improper installation. I used these anchors to mount a 14" x 14" sink under a marble counter and used a thick two-part epoxy that I purchased from Harbor Freight. The result was a perfectly solid attachment of the sink. It's important to note that thin glues should be avoided and thicker adhesives are preferred for a better hold.

Not only did these anchors work perfectly for me, but they also replaced the old rusted ones that were holding our sink in place. It's clear that these mounts are of great quality and, when paired with the appropriate adhesive, they hold very well. Just make sure to choose the right adhesive that matches the countertop you are using.

I recently purchased the white undermount sink from Kraus and I am absolutely thrilled with it. Not only is it visually stunning, but it also offers ample space and depth for all my kitchen needs. The sloped design ensures that water flows smoothly towards the drain, making cleanup a breeze.

One of the standout features of this sink is the included accessories. The silicone-coated drying rack, which conveniently rolls up, and the cutting board have been incredibly useful additions to my kitchen. I was initially concerned about potential staining, but I have washed dishes with red pepper oil sauce without any issues. The sink's sturdy yet not overly hard material and matte, non-slip surface make it both durable and safe to use.

Unlike porcelain sinks, this one does not require a protective rack at the bottom to prevent dishes from breaking. It is evident that Kraus has put great attention to detail and quality into this product, as both the contractor who installed my countertop and the plumber commented on its excellent craftsmanship.

I was also pleasantly surprised by the affordability of this sink, especially considering its high quality. It is a far superior choice to stainless steel sinks, which I was eager to move away from. The lightweight nature of the sink may initially raise some concerns, but a closer look at the product specifics reveals that it is a perfectly suitable option.

While the surface may not have the sleek touch of porcelain or stainless steel, it remains smooth and functional. I have had no trouble soaking dishes for extended periods, and various liquids, including coffee, soda, tea, and tomato products, have been poured down the drain without leaving any stains.

In my quest for the perfect sink for my kitchen remodel, I encountered several challenges, particularly in finding an undermount sink that was 30 inches or less. However, Kraus came to the rescue with this exceptional product. It complements my gold fixtures, black cabinets, white/gray countertop, and white backsplash beautifully.

Additionally, I appreciate that Kraus offers aftermarket accessories for the sink. This sets them apart from other companies I considered, as they only sold sinks with accessories and did not provide the option to purchase them separately.

I am absolutely thrilled with this sink! After using it for six months, it still looks brand new. A simple cleaning with vinegar and wiping it with vegetable oil is all it takes to keep it looking great. Even though we live in Denver where the water quality isn't bad, there aren't any scratches on the sink. We even clean our heavy cast iron pans in it without any issues. I don't think I'll ever go back to using the ugly, spotty, and scratched stainless steel sinks again!

I want to highlight that the sink is not only beautiful but also functional. The first picture I have attached is after not being cleaned or oiled for about a month, and as you can see, it still looks impressive. The second picture is after oiling it, and the shine is just amazing. Additionally, the sink has a useful feature where we can use the edge to hold cutting boards, just like other more expensive sinks. This has been a game-changer in our kitchen.

Moreover, the sink's size is perfect for my son's bumbo chair, making bath time a breeze. My back is grateful for this added convenience. I must mention that the sink arrived in perfect condition, without any cracks, despite some reviews mentioning this as a common issue. It seems to be very durable and scratch-resistant, which is essential for us as we primarily use cast iron cookware. We have been using the sink almost every night to wash heavy cast pans and a large griddle, and there have been no issues whatsoever.

It's worth noting that when our stone guy came to measure for our counters, he mentioned, unprovoked, that this brand is of higher quality compared to others he has installed. This further solidified our confidence in this sink. We purchased the InSinkerator flange separately from Amazon to complete the installation, and it worked perfectly.

The sink is even more stunning in person, with its roomy design and a subtle sparkle in the right light. However, the only flaw we could find was with the mounting equipment. The sink is quite heavy, and the brackets provided were not up to the task. We ended up bracing it from underneath with boards, which solved the issue.

I purchased this sink six months ago to replace my old stainless steel sink and faucet in the kitchen, and I must say, it has exceeded my expectations. The design of this 25" sink provides a larger working area compared to my previous sink. The unique bump out feature is not only aesthetically pleasing but also practical. The depth of the sink is perfect, and the width allows me to place a full baking sheet flat at the bottom.

One of the standout features of this sink is the offset drain, which provides ample space for resting dishes or draining items. To enhance its functionality, I added a 3/4 horse disposer and an air switch between the faucet and soap pump. I also took advantage of the precut circles underneath the sink to attach additional accessories using an inexpensive stone cutting drill. Despite being a novice at sink installation, I found the process relatively easy and took my time to ensure a great outcome. It took me a leisurely afternoon to upgrade from my old dented stainless steel sink to this luxurious granite sink with an industrial wand faucet.

I came across a review mentioning a staining issue, and I discovered the reason behind it. The review mentioned a whitish mark left in the sink after soaking a hot baking dish. It turns out that composite granite sinks, like this one, have a binding agent that is susceptible to color change when exposed to temperatures above 140 degrees. To avoid this issue, it is important to let your pans cool before placing them in the sink.

The only downside I have encountered is with the separate drain accessory that is listed on the same page as the sink. While it looks great in black, it does not effectively catch food particles in the sink. Therefore, I would recommend considering a different drain accessory that offers better functionality.

I recently had to replace my cracked bathroom sink and decided to go with an American Standard model. However, I quickly realized that the clips provided with the sink were not as easy to install as I had anticipated. The process involved drilling into the granite and securing a threaded insert with epoxy, which proved to be more challenging than I had expected. Even after trying different types of epoxy and thoroughly cleaning the surface, the inserts would spin and the epoxy would fail when attempting to tighten the screws.

After multiple attempts, I started to think about an alternative solution that would provide a stronger grip. I came across these countertop clips on Amazon, which seemed to align with my vision. The design of the clips with holes for epoxy penetration and stubs to prevent spinning seemed promising. Considering the frustration and time spent trying to make the original clips work, I decided to give these a try, especially since they were priced reasonably at less than $15.

Installation with these clips was significantly faster compared to the previous ones. It took me only 15 minutes to epoxy them to the countertop, whereas drilling holes and working with the old clips had taken over an hour. I allowed the epoxy to cure for 36 hours to ensure maximum strength, even though the recommended curing time was 24 hours according to the PC-7 epoxy I used.

Upon checking today, I found that the clips were securely attached, and I was able to tighten the screws without any movement or spinning of the anchors. I truly regret not purchasing these clips along with the sink initially. The installation process was quick, easy, and most importantly, I am confident that these clips will provide better durability than the ones I had previously struggled with.

I am extremely satisfied with this sink! It has been a month since I installed it and I am amazed at how it has resisted hard water stains and maintained its smooth finish. I have used various substances, from enchilada sauce to tough cleaners, and none of them have left any stains or scratches on the sink.

What's even better is that I found this sink on Amazon at a much lower price compared to what my countertop shop was offering. It is not only sturdy but also aesthetically pleasing. Even with regular use, I haven't been able to damage it with any dishes or utensils. Although it turned out to be deeper than expected, resulting in the loss of the garbage disposal, I am still happy with my decision.

After six months of use, this sink still looks brand new. There are no stains, scratches, or any other marks on it. Cleaning is a breeze, no matter what I throw at it. Additionally, it doesn't resonate as much as my previous stainless steel sink and it provides more space due to its wider and deeper design. I highly recommend this sink for its durability and aesthetics.

I recently had this sink installed and I am thrilled with the results. It looks beautiful in my kitchen and after a month, it still looks as good as new. I love the size of it and have even bought a rack for the bottom to prevent scratches. The ample space allows me to comfortably wash dishes and keep a dish rack next to it for drying, saving me valuable counter space. So far, it has been easy to maintain and keep clean.

After using this sink for eight months, I can confidently say that it is worth every penny. It has proven to be incredibly durable, showing no signs of wear despite being heavily used by my family of four who cook most meals at home. There are no stains or chips to be seen. Any lingering color is easily removed with some barkeepers friend. Not only is it durable, but it also enhances the overall look of my kitchen, especially when paired with my butcher block counters. I constantly receive compliments on this sink and I am glad I didn't opt for a boring stainless steel one.

I have been using this sink for three months now and I must say, I am thoroughly impressed. When I renovated my kitchen, I had to switch from a double sink to a single sink, but the depth of this sink more than makes up for the loss in width. It did pose a slight challenge for the plumber during installation, as the previous sink was not as deep and the plumbing was not designed for this depth. However, the plumber managed to make it work by using an extension piece on the old pipe to reroute it properly.

In terms of durability, the sink has remained stain-free so far. However, I have been diligent about not allowing anything to sit for too long in the sink. The maintenance has been relatively easy, with food bits drying onto the sides but easily coming off with a sponge, similar to my previous stainless steel sink. I try to wash and wipe the sink each night, and have noticed that water drains a bit differently due to the flat design, but this is a common issue with deep sinks.

The size of the sink is perfect for me, as it is much more functional and spacious compared to my old 32" 50/50 drop-in sink. This has provided me with more counter space, which is a bonus with my new quartz countertops. I will update this review if I encounter any difficulties in terms of cleaning or notice any staining in the future.

Another aspect that I am pleased with is the color of the sink. I opted for the white option, despite having a roommate who is less careful with the sink. However, I was pleasantly surprised to find that even after emptying Indian lentil soup with turmeric into the sink, there was no staining. A thorough rinse ensured that no residue was left behind. The sink has been as easy to maintain as a stainless steel one, with food bits easily coming off with a sponge.

Furthermore, the grey color of the sink is great at hiding dirt, and it complements our granite grey and white countertops beautifully. Only time will tell how easy the sink will be to maintain in the long run, but for now, I am extremely happy with my purchase. It is worth noting that the sink fits perfectly into a 30" cabinet, and I would recommend purchasing a drain kit to install with your garbage disposal. We used a standard silver kit, but black would also work well.

I recently moved into an older house and encountered a problem with my kitchen sink. After just a few weeks, the sink fell in, leaving me unsure of how to fix it. I didn't want to drill holes into my countertop to install new clips, so I started searching for alternative solutions. That's when I came across these glue on clips on Amazon, and they turned out to be a great solution for my problem.

However, I must admit that the project wasn't exactly easy. I had to scrape off all the old silicone and thoroughly clean the underside of my marble countertop with alcohol and a wire brush to ensure a good epoxy bond. I marked the locations for the clips on the countertop using masking tape and used Gorilla 5 minute epoxy to glue them on. It was important to leave enough clearance between the lip of the sink and the clips. I found that using clamps to hold the clips in place until the glue set was necessary, as they tended to fall off otherwise. After letting the glue dry overnight, I applied a bead of silicone around the top of the sink and braced it from underneath to ensure proper pressure until the silicone dried. Finally, I tightened the clips and removed the under sink braces.

I'm happy to report that, so far, the combination of the clips and the silicone adhesive has been working perfectly. It has been about a month and a half since I completed the project, and the sink is still securely in place. In fact, it has been about a year now, and the clips are still doing their job. I did have one clip fall off after a couple of weeks, but that was due to an uneven surface caused by old adhesive from the original installation, which I couldn't remove. However, the sink remained secure, so I simply left that clip off. We use the sink every day, and I have no doubt that it will continue to provide us with many years of trouble-free use. I'm still very satisfied with the results.

Another user mentioned that they used these under-mount anchors on their granite slab before installing the sink. They cleaned the underside of the slab and applied a syringe of 2-part epoxy to dispense the adhesive. They then dropped the anchor into the adhesive and pressed it against the stone, ensuring an even layer of epoxy around the bracket. They repeated this process for each anchor, waiting for the epoxy to cure before moving on to the next one. Tightening the anchors made it easy to apply RTV around the sink base. They have high hopes that the epoxy will hold for years and will update if anything changes. They highly recommend these anchors for ease of sink installation.

I am extremely satisfied with this sink. It complements my newly installed quartz countertop beautifully. The matching sink drainers are top-notch and add to the overall aesthetic appeal. The sink itself is not shallow, fitting perfectly and adding a touch of elegance to my kitchen. I was initially surprised that it wasn't pure white like my bathroom porcelain, as it had tiny flex marks in it. However, it turned out to be a perfect match with my Linen N countertop from Arizona Tile. Despite my initial reservations, I am extremely happy with this purchase as it brought everything together in a way I didn't expect. This is my first non-pure white porcelain sink, and I absolutely love it.

The packaging was excellent, ensuring that the sink arrived in pristine condition. I was impressed with the stylish presentation, which perfectly complemented my newly installed granite. The range of colors available is also worth mentioning, and we ultimately chose griege, although several other options were equally appealing.

The installation of this sink was a breeze, thanks to the undermount sink brackets. It is worth noting that it is a two-person job. The dark color of the sink beautifully complements my stainless steel components and faucet, creating a stylish and cohesive look. Cleaning the sink is effortless, as it easily wipes clean with dish soap and water using a regular scrub sponge.

I purchased this sink to replace a cracked one in my kitchen, and I couldn't be happier with my decision. The undermount design fits perfectly and looks fantastic with my granite countertops. To complete the look, I also ordered the black Elkay Polymer Drain Fitting with removable basket strainer and rubber stopper, which added the finishing touch I was aiming for.

I am extremely pleased with my purchase of this sink and faucet combo. The sink has a beautiful black granite look, which was a pleasant surprise considering the pictures make it appear satin black. The sink arrived in immaculate condition, despite the box being a bit banged up from shipping. It was well-packed and protected.

The pre-drilled holes in the sink were clearly marked and there were 5 in total, with one hole being used for the faucet. The other holes are pre-drilled about 80% of the way through, making it easy to drill out additional holes if needed. Just be sure to have the proper size and type of hole saw bit.

I paired this sink with a Kraus Bolden faucet and a Waste King Legend disposal, and the combination is perfect. I have no complaints about the sink and would highly recommend it to anyone in search of a quality composite granite sink. It's a great choice for those unsure about which brand to choose.

Installing the sink was a bit intimidating for someone who had never done it before, but with some research and the right tools, it was a smooth process. I purchased additional items from Home Depot to complete the installation, such as a tail piece extension, silicone, PVC cutter, Kraus drain cover, plumber's putty, and an underlayment to cover up water-damaged flooring temporarily. I also replaced the disposal mounting kit with a new one to ensure everything was in top condition.

Removing the old sink and dry-fitting the new one was a relief, as the new sink fit perfectly in the slightly larger opening created by the previous contractor. I used the black spacers that came with the sink installation kit to secure it to the countertop. The mounting clamps were easy to use, and the hardware provided was of good quality. Tightening the screws in a wheel-like pattern ensured a secure fit.

The plumbing lined up perfectly, and I was able to connect the tail piece to the P-trap without any issues. Installing the faucet was a breeze, with just a simple drop-in and tightening of the nut and locking screws. Connecting the water supply lines was the final step before turning the water back on.

Despite the description stating that a 36" wide cabinet was needed, the sink fit perfectly in my 34.5" cabinet. There was ample room to mount the clips, although a long #2 Phillips screwdriver was necessary. The sink also comes with hardware for under-mount installation if that suits your needs, as well as a drain if you don't have a disposal.

The sink has knockouts for a soap dispenser or air gap, but I chose not to use the air gap. Instead, I ran a loop higher than the line feeding into the disposal and secured it with zip ties to one of the mounting clamps. My wife loves the sink, especially the large basin and single drain on the right side. The surface area is spacious enough to accommodate pots, skillets, and cookie sheets without them hanging over the top.

This upgrade was both nice and affordable. The sink and faucet arrived earlier than expected, which was a pleasant surprise. The quality of both items exceeded our expectations. The Kraus faucet (KPF-1610SFS) is a perfect match for the sink, and both are solidly constructed. The sink is a great alternative to stainless steel, and it looks much more expensive than it actually is. Overall, I give this combo a five-star rating.
