Top Granite Sink Quick Chart

Granite composite kitchen sinks are still relatively new in the market and before you jump on the bandwagon, be sure about what elements should be taken into consideration when judging which is the best granite sink for you and if it fits your lifestyle or not. Below are the top features you should be scrutinizing when researching your desired granite composite sink: 

  • Quality: The quality of the composite granite sink is without doubt the most important feature that must not be compromised on. However be sure that the amount you pay for the sink is justified by the quality you receive. This does not mean only the expensive sinks are good, rather if you do your research well you may be able to find a good quality sink at a reasonable price too.
  • Durability: Sinks are subject to heavy pots, pans and ceramic dishes. Not to mention the poor quality hard water that is supplied in many places, the sink goes through a lot of wear and tear. Look for sinks that have thicker bottoms, or ones that feel more natural than others, as the higher amount of granite in the sink the stronger and more durable it will be.
  • Dimension (Inches): The dimension of the sink you are about to purchase should be studied well. If you wish to install it on a pre-existing kitchen counter make sure it fits within the counter limit. If you are selecting a sink for a brand new kitchen, you may even design your counter around the size of the sink. In such situations, look for a sink that is large enough to fit your biggest baking tray or pot.
  • Installation: Installing sinks is not a piece of cake for everyone, and can sometimes involve more technical know-how than you imagined. Especially with sinks that have the rim showing, you need to be very sure about what size the cut out in your kitchen slab should be so that no mistakes are made to be regretted later on. Hence, look for a sink that is easy to install and requires a minimum amount of additional materials.
  • Constant color: Granite composite sinks are made up of 80% natural granite and 20% chemicals and binding substance which make it possible for the sink to have a single monochrome effect. 
  • Sound deadening: No one likes to be in a kitchen when pots and pans clank against each other while washing, but the worst sounds are when they hit against the surface of the sink and make an ever more irritating noise. Some composite granite sinks have special sound absorbing features that make a huge difference and should definitely be on the lookout for.
  • Resistance to agents that could cause damage: The kitchen sink is one accessory in the kitchen that is overused and subjected to the harshest materials, agents, and contrasting temperatures. While most granite kitchen sinks are pretty good when it comes to being resistant to damage, some may not be as promising as others. Make sure you read the fine print as well as reviews before you make the purchase. 
  • Hygiene: The level of hygiene that kitchen sinks offer should not be overlooked. Not only does food come in constant contact with your sink, but so do your crockery, dishes, raw vegetables, and fruits. Keep in mind to look for a non-porous sink that does not react with your raw or cooked food in any way. 
  • Heat-safe: A sink that can take higher temperature if heat as compared to other granite composite kitchen sinks is a better option so that you can work freely in the kitchen without having to be cautious at all times. If your sink cannot take a lot of heat, a hot pan or pot may lead to cracks in the sink. 
  • Scratch resistance: A sink that does not take on scratches easily is a blessing, so that you do not spend hours trying to figure out how to get rid of the scratches. Scratches obviously do not look good, but also result in soap remnants getting stuck in the narrow grooves that are created, making the sink dirtier than it should have been. 
  • Easy cleaning: It is pains to own items or appliances in the kitchen that require extra love and care especially when it comes to cleaning them to maintain a spic and span kitchen. A granite composite sink that is darker in color, has a layer of protection against spots and stains and that has an easy drain angle will make the cleaning process easier for you.

Advantages Of Granite Sink 

  • Heat-resistant: Granite composite sinks have a decent resistance to heat and neither do they fade nor get discolored when they come in contact with high heat. 
  • Durable and damage resistant surface: The composite granite sink surface is well protected and no amount of acid, scratching, chipping or staining takes place.
  • Abundant color options in matte finish: Because the granite is composite literally any color is possible to make the sink in, and brown is the most popular as it is not found in any other material.
  • Long life: The composite granite sinks are long lasting because of all the above qualities making them a popular option for sinks right now.
  • Durability and look of natural stone at less than half the price: What you get at the price you pay is almost like a steal.

Disadvantages Of A Granite Sink

Special care against piping hot pans: Piping hot pots and pans must be allowed to cool down a little and only then placed in the sink as the heat on a vessel when it is just off the flame can be a bit much for the sink to handle, which may result in cracks.Regular maintenance is a must: Composite granite sinks require regular maintenance but a fairly easy one, just to make sure no water remains or food remains are left in the sink and they are patted dry after use. Lighter colors may show stains. The finish of the sink may start becoming dull because of waterborne minerals if cleaning is not regular.

The quality and features of a kitchen sink are just as important as those of a hob, oven or chimney. If you love design as well as cooking, then composite granite sinks are just for you. They let you enjoy the benefits of both a great look as well as great benefits at the same time from one single piece of kitchen accessory. Cleaning granite composite sinks is also easier than other sink materials and your kitchen looks upgraded with a single change. Let us know in the comments section which is your favorite composite granite kitchen sink color, and if you prefer countertop sinks or those that fit under the counter!

Expert’s Answers for Readers Questions

Are granite composite sinks durable?

Granite composite sinks are hygienic, nonporous and resistant to stains, scratches and heat and chips. They are a good durable option for kitchen sinks and cna have a long life.

Are composite granite sinks better than stainless steel ones?

The features of kitchen sinks depend a lot on your use and style of cooking and washing. Granite sinks are way better than steel sinks when it comes to being hygienic and resistant to scratches and dullness, however if you are used to draining boiling hot water into a colander right at the sink, then steel sinks are a better option for you.

Is there any difference between a composite sink and a granite sink?

Yes there is a difference between the two. Each natural granite sink will be unique and will have variations in color and pattern across the sink whereas a composite granite sink is composed of 95% granite and 5% resin, because of which all sinks will look almost the same and will have a monochrome surface.

What are the daily care instructions for a granite sink?

A simple cleansing ritual is enough for granite composite sinks. Soapy water and a regular but soft sponge can keep your kitchen sink spic and span. Do not forget to dry off the sink by wiping it after a wash.

Could vinegar or ammonia harm a granite composite sink?

Products that are high in alkaline or acidic content are not advised to be used for cleaning a granite acrylic sink. Even pouring these products into the sink while washing can prove as a threat and they should be washed down immediately or the resin coating will develop some abrasion.

What is a self-rimming sink? Is it the same as top-mount installation?

Self-rimming sinks are those that are made with a lip that is beyond the circumference of the bowl. This lip sits on top of the kitchen counter top while the sink bowl drops into the cutout. Yes, both self-rimming and top mount are the same thing, and are also the most common types of sinks that are available out there.

Are granite sinks hard to keep clean?

No, they are not hard to clean at all. They don’t show as many scratch marks and dull spots the way steel sinks do, and are way ahead of ceramic sinks as far as basic black marks are concerned. As long as composite granite sinks are cleaned using soapy water and a sponge, they will not show any stains or marks.

Can granite composite sinks crack?

Yes granite composite sinks can crack if hot water is poured directly into them, or a hot vessel is placed into the sink. Heavy pots and pans also have a tendency to cause chipping in these sinks so one has to be very careful and cautious.

Can granite cracks be repaired?

Yes, they can be repaired depending on how large the crack is. If it is a thin crack, they can be easily repaired either by using the same color epoxy or an acrylic to glue the split pieces together. A very large crack may be harder to repair and conceal.

Can I use Windex on granite?

No, do not use Windex or any acid or bleach on granite sinks. The sealant of the composite sink will weaken and it may develop cracks. The good news is you do not use any special type of cleaners for granite composite sinks. Just simple soapy water will suffice.
