Review: I bought this sink for my wife with the pictured faucet as a birthday gift. Both are Kraus. I, having never installed a kitchen sink, was a little apprehensive about the install. I did all my research and made one trip to Home Depot for the things needed to install (Tail piece extension for plumbing modification, silicone, PVC cutter, Kraus drain cover, plumber's putty and a 5mm underlayment to cover up the water damaged flooring of the cabinet - it's temporary). I also got a new Insinkerator disposal mounting kit with gasket for disposal because the other one was scratched and worn. I got back home and proceeded to remove the 20 years worth of cleaners and stuff from under the sink. My hope was that the plumbing would line up perfect where my existing sink drain was and that the sink would fit perfect in the opening. Once I got the old out and dry fit the new sink there was a sigh of relief. The contractor cut the opening slightly larger than they should have for the prior sink so the new sink just barely fit and covered. It's close but it is covered. I had to use the black spacers that come with the sink install kit in order to tighten it down to the counter top. After dry fitting several times and making sure I had everything in order I ran one bead of clear silicone around the perimeter of the sink and set it in the opening. I adjusted it from side to side and front to back to make sure it was exactly where it needed to be then I started tightening down the mounting clamps. I like the hardware the sink comes with - the mounting clamps fasten to the sink with phillips head screws before you install then all you have to do is spin the clamp 45 degrees and tighten the phillips screws to snug it to the counter top. I tightened the screws like you would a wheel on a car - then I went around and snugged them down. I installed the disposal next and the tail piece lined up perfect with the p-trap as I had hoped it would. I measured and cut the tail piece and buttoned up the plumbing. Then I installed the faucet which is super easy. Drop it in the hole, tighten the nut hand tight then there are two locking screws with phillips head. After that all you have to do is hook up your water supply lines and turn the water back on. The description says you need a 36" wide cabinet but you can see in the images my cabinet is 34.5" inside and it fits perfect. There was plenty of room to mount the clips - you will need a long #2 phillips screwdriver. It also comes with the hardware for an under mount if that fits your application. It comes with a drain as well if you do not have a disposal. The sink comes with knock outs for a soap dispenser or air gap. I ordered the Kraus faucet with air gap because it was the only spot free stainless option. I did not use the air gap. I ran a loop up higher than where the line feeds into the disposal (found that handy info on YouTube) and zip tied it to one of the mounting clamps to hold it. All in all she loves it. The Kraus faucet with this Kraus sink is a perfect match. The sink is solid and seems to be very well made. The faucet feels high quality / heavy. The basin of the sink is huge compared to what we had and she loves the single drain on the right - you have a lot more surface area to use in the sink. She can now fit an entire pot, skillet or cookie sheet in the sink without it hanging out the top. This was a nice, inexpensive upgrade. When I ordered both items the faucet was $209 and the sink was $206. Both items arrived days earlier than desertcart promised so that was a bonus. We love the sink and not a single thing went wrong during the install. Everything went exactly the way I wanted. Not the way I expected which would have been just short of a disaster like most projects around here. The Kraus faucet I installed is the KPF-1610SFS - https://www.desertcart.com/gp/product/B0956JW96Z/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&th=1 If you are looking for something that won't break the bank but looks like it did - this is a great combo. Everyone who has seen it says "I don't even want to know what that cost". I was looking at stainless sinks before I found this one and I'm so glad we went this route over stainless. It is top notch. Five stars for sure. Review: Gorgeous sink that is the focal point of our kitchen island. We were reluctant to go from what we have always known as the standard stainless double basin kitchen sink to a black granite composite single basin sink but are so very pleased with how amazingly beautiful it looks with the contrasting granite countertops color we chose 'bianco antico'. We also purchased the VIGO VG02001MB Matte Black Pull-Down Spray Kitchen Faucet and all we can say is WOW. What a fantastic combination. The sink is huge compared to a double basin and is solid and well made. Kraus makes a great product that is far less expensive than its competitors. ## Features - Undermount DESIGN creates a seamless transition from sink to countertop and makes it easy to wipe water and crumbs into the sink - Dimensions | Overall – 30.5” L x 17” W x 8.88” D | Bowl – 28.37” L x 14.5” W x 8.88” D | Minimum cabinet size – 33” | Drain opening – 3-1/2” - KITCHEN SET INCLUDES: Sink, Basket Strainer, Kitchen Towel, Mounting hardware, cutout template LIFETIME LIMITED and customer service that puts you first - NATURALLY HYGIENIC material enriched with silver ions that repel germs for a cleaner sink | LOW MAINTENANCE SURFACE is highly resistant to dirt and grime, and easily wipes clean - A QUIETER KITCHEN SINK: Thick stone like material engineered to eliminate vibration and noise when the sink is in use NON FADING COLOR with UV protection for a rich and consistent hue that will not dull over time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E6SP5R0 | | ASIN | B00E6SP5R0 | | Best Sellers Rank | #69,222 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #157 in Single Bowl Kitchen Sinks | | Brand Name | Kraus | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (2,819) | | Customer reviews | 4.6 4.6 out of 5 stars (2,819) | | Date First Available | 6 March 2014 | | Drain Type | Basket Strainer | | Finish Types | Matte | | Global Trade Identification Number | 00846639017541 | | Included Components | Basket strainer, Kitchen Towel, Mounting Hardware, Sink | | Installation Type | Undermount | | Is Discontinued By Manufacturer | No | | Item Dimensions D x W x H | 43.4D x 77.4W x 22H centimeters | | Item Type Name | Workstation Quartz Composite Single Bowl Farmhouse Kitchen Sink | | Item Weight | 30.36 Pounds | | Item model number | KGU-413B | | Manufacturer | Kraus | | Manufacturer | Kraus | | Manufacturer Part Number | KGU-413B | | Material Type | Quartz, Resin, Stone | | Model Number | KGU-413B | | Product Care Instructions | Wipe with Dry Cloth | | Product Dimensions | 77.39 x 43.41 x 22 cm; 13.77 kg | | Shape | Rectangular with Rounded Corners | | Size | 31 Inch | | Style | Undermount | | UPC | 846639023276 846639017541 | | Unit Count | 1 Count | ## Product Details - **Brand:** Kraus - **Colour:** Black - **Material:** Quartz, Resin, Stone - **Product dimensions:** 43.4D x 77.4W x 22H centimeters - **Size:** 31 Inch ## Images ![Kraus KGU-413B 31 inch Undermount Single Bowl Black Onyx Granite Kitchen Sink - Image 1](https://m.media-amazon.com/images/I/71zwf6EYmaL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Can double check if it comes with the strainer and towel?** A: It does come with a strainer. **Q: is it dark b;ack or more of a dark, charcoal?** A: Black.
