My Search for a Kitchen Sink: How I Chose the Blanco Silgranit II Granite Composite Sink

How much can you say about a kitchen sink? As I found out, quite a lot! In this updated long-term review of the Blanco Silgranit II granite composite sink, I hope to share with you how satisfied we have become with our purchase. I also want to share where you can find some of the best prices.

While planning an extensive kitchen remodel, I knew that we were going to replace our sink. When the search started, I had no idea that there were so many choices. I mean, a sink is a sink, right? However, after some initial research of reviews and recommendations from family and friends, we decided on a Silgranit II granite sink by Blanco. I must admit that after two years, I am still very impressed with our selection. When I installed it, I had no idea how much value, practicality, and beauty a good sink would add to our kitchen.

Why a Granite Sink?

The Silgranit II is a composite sink manufactured from 80 percent granite and cast in a single pouring. Unlike natural granite, granite composite is not porous. That means it resists stains, is safe for all foods and, according to Blanco, is fully hygienic. It’s also much lighter than the typical cast iron porcelain sink, which means you can undermount it as well.

Other features of this sink are that it is resistant to alkalis and acids as well as scratches and chips. I learned the latter firsthand when I accidentally dropped a 10lb cast iron cooking grate from my soapy hands onto the center divider! Another feature that I found surprising is that the sink has a soft feel to the touch.

What about heat, you ask? Well, these sinks are heat resistant up to 536 degrees Fahrenheit. That means you can dump your big boiling pots of water from cooking pasta into the sink without any worries. I do it all the time. During my research I started to find an unwarranted opinion that granite sinks have a tendency to crack when doing this. After quite a bit of investigation, I could only find one person who actually reported this happening, and it wasn’t a Silgranite II sink. In fact, Blanco gives you a lifetime warranty.

In Short, the Best Features of Composite Granite Sinks Are:

  • They are incredibly easy to clean.
  • They are lighter than porcelain, which allows your to undermount them.
  • They are resistant to chipping and scratching.
  • They do not clang when hit with pots and pans.
  • They can handle high temperatures.
  • They come in a wide variety of colors.

Below, I will go more in detail.

Are Granite Sinks Are Hard to Keep Clean?

No, they are not! These sinks are unbelievably easy to keep clean and looking like new. They don’t leave water marks, scratches, or spots like stainless sinks might, and there are no black marks to constantly be rubbing out as there are with porcelain ceramics. A little dish soap and a sponge is all it takes for a quick clean-up.

Two members of my family have the white- and biscuit-colored sinks that will occasionally get a black mark from dark-colored pots rubbed hard on the sink. They report that the marks come right off with the scrubby side of a sponge. If for some reason you have neglected regular maintenance or have particularly hard water that has lightened the look of the darker colored sinks, Bar Keeper’s Friend and a little mineral oil brings out a brand-new luster.

Silgranit II Stain Test

Will Granite Go with My Kitchen Décor?

Yes, that’s one of the best parts about choosing these sinks. Unlike stainless and most ceramic sinks, they come in seven different fashion-conscious colors and 23 different shapes. You can choose to accent your countertop with a contrasting color or blend in with a less-conspicuous choice. They are available in either the classic drop-in or stylish undermount configurations.

So, How Do I Like My Sink?

The sink we chose was the undermount Diamond Equal Double in metallic gray. Since our countertop is a darker, grayish-blue quartz, this color provided a lighter accent of the same color tone. It also goes extremely well with the stainless faucets and décor we have around the kitchen. Keep in mind that when ordering, drain flanges and strainers are not included. They can be ordered separately or purchased at any local hardware store.

The first thing that stood out was the depth of these sinks. Most are two to three inches deeper than your standard sink, which I love. It makes it so much easier to handle and wash big pots and pans without splashing water all over the place. One note: Make sure to account for this additional depth in the sink when it comes to installation. It might require a slight redesign in the plumbing underneath so that your garbage disposal and trap are aligned properly with the house drain pipe.

The other benefit I noticed with granite composite was that water kept its temperature much longer than a stainless sink.

It’s also much quieter. There is no more of the hollow-sounding banging around of pots and pans.

The most attractive part of this sink is how I usually clean up afterwards: Just rinse and go! Living in Southern California, we have extremely hard water. I’m amazed that after two years now of mostly light cleaning we haven’t had to scrub out any hard water spots.

Best Prices for the Blanco Silgranit II Kitchen Sink

As I said earlier, I wanted to share with you where you can find the best prices for the Silgranit II kitchen sink. After we did a lot of shopping around and visited participating dealers in our area, we found that we were consistently finding the best prices for various models on Amazon and E-Bay. Amazon prices are so low that they are restricted from posting advertised prices until you click onto their site.

However, this doesn't mean that you can't find a better price for the Blanco Silgranit II in your area if you have time to wait for a special promotion from a local dealer. My brother actually saved money when he found a dealer in his area that offered a free installation with the purchase of the sink. The sink itself didn't have a particularly low price, but the combined savings of the sink and installation was a deal he could not pass up.

In Conclusion

I really like our Blanco Silgranit II kitchen sink and would highly recommend it to anyone looking for a new replacement. Admittedly, they are more expensive than most quality stainless and porcelain models, but the price is well worth the difference. If you want a sink that is beautiful as well as extremely functional and easy to keep clean, then the Blanco Silgranit II may be the sink you have been looking for.

      I've had my (Anthracite) Blanco Silgranit for 5 years. After a year, it developed a really unattractive faded/white area in the middle which seems to be getting larger. I've been scrupulous about using correct cleaning products and not putting hot pans into the sink.

      I purchased this sink through a well-regarded kitchen supplier in Portland. (I mention that, because I've heard that the Blanco sinks sold on amazon and at Home Depot are of different quality, but I don't know whether that is correct.) I wouldn't recommend that anyone purchase this sink. It looks beat up after a short time and even trying the mineral oil trick to revive it doesn't work. I'll be replacing it with stainless steel. Sad, because the original color looked amazing with my counters.

      I have a Blanco granite (anthracite) kitchen sink that I bought five years ago. It has discoloured horribly. I bought their special cleaner, and it did nothing. Although Blanco says it has a life time warranty, you have to have the original box it came in and the receipt, and they will not install the replacement. So good-bye Blanco. Never again.

      I owned a white Blanco silgranite for years with no problems. LOVED this sink so much that I ordered another for our granite countertop renovation. It now has two cracks toward the top of the sink. Waiting to hear from Blanco. Hoping to get a new one!

      This is the worst remodel purchase I have ever made. It does not clean even the simplest kitchen use. I also have friends with the same experience. I have tired the recommended cleaners and the entire product is absolutely a disaster. I live alone and have no more than rinsing dishes in the sink. I cannot say it LOUD enough do not by this product.

      We have found that BonAmi or Bar Keepers Friend along with a soft scrub sponge works well at removing marks, rings, and etc. If that doesn't work, I would suggest contacting Blanco to see what they recommend.

      I have a dark brown color and for the most part I've been satisfied; no cracking or chipping, I pour boiling water in it without a problem. One major issue for me is a white discoloration that looks pretty bad and I can't seem to get rid of. Tried Barkeepers Friend and even granite cleaner. Don't think I would go with a dark sink again.

      These sinks are Trash!! Buyer beware. They might be attractive but they are not durable. Ordered a Blanco Silgranite sink. Arrived in an undamaged box with the styrofoam inside fully intact without damage. Everything looked fine. However, 2 months later when it cam time to install in my remodel project, when I unpackaged it fully, there were hairline cracks in two corners going down into the bowl. Place where I purchased it refused to take responsibility. Called Blanco and they refused to help and would not back their product. There are many complaints online of these sinks cracking. Once cracked they are worthless as there is no adequate way to repair them. I will never buy another Blanco product again. this company does not stand behind their product.

      Disappointed 10 months ago

      My Silgranit sink accumulated more than 20 chips in the surface in less than a year of use. I have the Diamond model in truffle colour. The chips accumulate dirt and some are large enough to appear as black spots, i.e. chips full of dirt--ugh!--and hard to clean. The company is sitting on their statement that they are not manufacturing defects and they are not liable for these things that occur during normal use over a period of time. Needless to say, I am very unimpressed with the product and the company. My advice: AVOID both!

      I just had an accident with Silgranit II by Blanco. The spice bottle fell in the sink and created a hole - can't believe it!! When I approached Blanco - the lifetime manufacturer's guarantee does not exist. This is surely a cope-out on their part, breaching an agreement between a manufacturer and consumer.

      Nancy you can go to this website and see all 3 types listed. I think it has to do with style, shape, price etc..but Im sure durability is the same. I have the diamond series I believe and have had since 2009 and its fabulous! Make sure you look at the specifications needed for the sink you choose. http://www.blanco-germany.com/en_us/en_us/sinks/si...

      Curious if there is a better model to get (i.e. does Blanco order their sinks like good, best, better?). I am looking at 3, all undermounts and single bowls: Precis 440150, Valea 441773, Diamond 441767 (my preference since offset drain). Prices are all over the place! I found great prices at Qualitybath.com

      That's a great question Alex. I know it's much more forgiving than porcelain, but how it compares to stainless in that regards I'm not sure. Hopefully someone who has experience with both can let us know.

      I want to know about the difference in this sink in regards to washing crystal. I love to use crystal but of course the crystal chips easily in porcelain sinks, less chipping of crystal in stainless steel sinks ...how does the granite sink compare. In other words if you knock a glass against the sinks' surface does the granite make it more likely to chip or less than porcelain or stainless ????

      Hello Busia. According to Blanco's instructions for the Silgranit sinks, you can soak a solution of 1 part bleach to 1 part water for up to an hour in their sinks. I believe to sanitize you would only need around 5 minutes or so, but I could be mistaken.

      Here is the link to their instructions: http://www.blanco-germany.com/media/media/20_bam_m...

      I love the beauty of the sink . However, I am worried about sanitizing the sink. I have small grandchildren, one has strep now. I use bleach daily in my sink now to sanitize. It seems there is now way to sanitize since you can not use bleach on the dark color . I do have the brown sink on order but I am thinking about changing to stainless only for sanitation purpose. Any information for me?

      Not all natural stone is porous - many granites are very dense and virtually nonporous (e.e., Absolute Black, Uba Tuba) and soapstone is nonporous. It's a common misconception that all "granites" and natural stones are porous.

      We use glass crockery - pots plates glasses etc. Does the same break easily if dumped in the granite sink???

    • byshea profile image

      Shea 3 years ago

      To be clear, I believe you are talking about underneath the counter? After almost 3 years, we have yet to contact the sink from under the counter. I know that ours has a rough surface from the casting, but the thought of being cut has never crossed our mind.

      Anyone else?

      I have not had any issues of breaking when I drop items unless it was a very fragile cheap glass to begin with. I'm pretty rough on things, and I still love my sink (mine is black).

      I don't usually make comments, but I read your review about 6 months ago and finally convinced myself to buy a Blanco Silgranit sink. I have the Diamond Equal Double in biscuit. I've never had a light colored sink like this and my last one was a stainless sink.

      I came back to let you know that this is the best sink I've ever had! It still looks brand new and I love how quiet it is compared to my old stainless steel sink. My family is Italian and I cook with big pans. I was a bit worried about scratches and possible stains (especially with a light colored sink) from my homemade pasta sauces. I don't even think about it anymore and I love how deep it is. If I was to do it over again though, I would have opted for the undermount style. I think it makes it easier to clean the counter.

      Sounds like a great sink. I like things that last and don't need constant repairs, and that most of all do the job I bought them to do. Practical, useful, easy to care for, reasonably priced, and attractive.

    • byshea profile image

      Shea 5 years ago

      Great question about the color fading. The color will not fade with these sinks, but they can develop a whitish residue from hard water deposits over time that will give the illusion of fading. According to Blanco, when this happens just clean the sink real well with a non-scratch cleaner like Bar Keeper's Friend or BonAmi and then rub it down with a little mineral oil. It will bring the color right back to new.

      That looks an awesome sink- I've just got on the property ladder and always looking for inspiration when it comes to home items. The only worry i have is that if I go for my chosen colour of black they can actually lose colour over time- any experience of this?

      Actually, one of the benefits to this sink is how easy it is to clean. Yes, they are more pricey than a good quality heavy gauge stainless sink, but in my opinion, if you are going to be using it multiple times a day it is well worth it. Did I mention that they come in more than one color :) ?

      They look like clay and hard to clean, but looks may be deceiving! I'm curious about this type of material for a sink. I agree -- stainless sinks sound noisy when the water from a faucet drips onto them.

      I bet these are more pricey than the usual stainless sinks? But judging from your hub it sounds like it's worth it.

      Up, useful and a following. :)
