Searching for a Kitchen 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.

A composite granite sink is extremely easy to clean and hard to chip.

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 you 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 watermarks, scratches, or spots as 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 bring out a brand-new luster.

Cleaning and Caring for a Blanco Silgranit Sink

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 afterward: 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 eBay. 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.

Extremely Beautiful and Functional

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.

Questions & Answers

Question: We put in a Blanco granite sink last January. We bought ours from Lowe’s. We already have three chips! We have the dark grey and the chips show white. This is very disappointing. Even if Blanco gives a lifetime warranty can our sink be replaced without damaging our quartz countertops?

Answer: Yes, you should be able to replace it without damaging your quartz counter top, particularly if it's an under mount sink.

Question: Is silgranit the same as a fraganite sink? I cannot seem to find a deep double bowl sink with the right drainage in Australia.

Answer: It is a very similar sink in terms of construction, but it's not made by the same manufacturer (Blanco).

Question: Can you rinse hair dye out in the sink?

Answer: I would suggest contacting Blanco to find out. We have rinsed latex paint from brushes and rollers in the sink without issue, however, dye is completely different.

Question: We have a double silgranit, white in colour, one side out the outlet has lost its smooth surface and has discoloured, what can we do to restore the surface?

Answer: I would recommend contacting Blanco customer service for such an issue.

Question: Does the sink come in more than one size?

Answer: Yes it does! I suggest you visit the Blanco website to review the sizes and options.

Question: What color of granite is the easiest to keep clean white, black or brown?

Answer: The metallic gray has been extremely easy to keep clean for us. I do hear more people complain about white. I can't answer for the other colors, however.

Question: Is there a quality car polish to help prevent hard watermarks?

Answer: I wouldn't recommend using car polish. You may develop a white haze that would be hard to remove.

Question: I have the brown Blanco granite sink, and it constantly has white buildup in the corners and along the divider. It is really gross! Whats the best way to keep that clean? I've tried bar keeper's friend, but it still happens all the time.

Answer: You may have hard water deposits that have built up on the finish. You may want to try a mixture of baking soda and hydrogen peroxide. Mix it into a paste and then scrub the sink with it using a soft, short bristle brush.

Question: My sink has a crack in the top corner. Will it continue to split?
