Granite composite sinks are manmade using a mixture of granite stone and acrylic resin. Fine granite sand is blended with an acrylic bonding agent with the result a material like granite, but with some extra qualities. Granite composite is more durable than natural granite, easier to maintain and cheaper.
Why Choose a Composite Kitchen Sink Anyway?
Unfortunately, few stainless-steel sinks survive for many years. Dropped plates, glasses and heavy pans can all damage a stainless-steel sink, meaning it’ll likely need to be repaired or replaced before long. Composite granite sinks on the other hand can survive the test of time - as well as the odd dropped saucepan.
Available in a wide variety of colours, composite sinks can add a personal touch or splash of colour to any kitchen. By adding dye to the acrylic resin virtually any colour of composite sink can be achieved. It’s also very easy to make a granite composite sink look luxurious - we love the look of a darker coloured granite sink, paired with a lighter countertop.
As composite sinks are a man-made product, you can be confident that the colour and texture remains consistent throughout. While natural granite has a sandy look, granite composite is much more uniform in colour and look, while still retaining some of that grainy charm.
Composite granite sinks are usually costlier than their stainless-steel equivalents. Due to their high resistance to wear and tear however, granite composite sinks are generally better value for money. If you put time and effort into looking after your composite sink, you’re unlikely to have any major problems with it for many years to come.
Perhaps something you wouldn’t think about until a family member starts running the tap full blast on a stainless steel kitchen sink at 6am, granite composite sinks are thick and dense meaning they absorb sound very well. Great news for that Sunday morning lie in.

The Problems With Granite Kitchen Sinks
Resistance to Chemicals -
While they may withstand the force of dropped pots and pans, granite composite sinks are easily damaged by harsh chemicals, which is why it’s important to take care when cleaning your sink. While stainless steel sinks can realistically withstand a whole load of eye-watering chemical concoctions, granite composites require a bit more care and attention.
Resistance to Heat -
Some composite sinks can be damaged by heat, but purchasing a high-quality sink which has been designed for heat resistance is the best way to avoid this. It’s also best to avoid putting extremely hot pots and pans on the surface. If in doubt as to your sink’s heat resistance, check with your manufacturer.
While the sink may not break when you drop glassware or china onto it, it’s likely that the crockery might. Granite composite sinks are notoriously unforgiving, so it’s best to just avoid dropping delicate objects altogether, although we know this is easier said than done.
Dropping a plate or glass onto a stainless steel kitchen sink is unlikely to result in too much destruction, but it may dent the sink instead of the plate. At the end of the day, it comes down to personal preference and confidence in your hand-eye coordination - just try not to drop too many monstrous saucepans.
While granite composite sinks are not necessarily difficult to install, they are heavier than stainless-steel. While this won’t be a problem for most people, if you feel your counter won’t withstand a heavy weight, it’s best to get professional advice. Realistically though, your kitchen counter is more than likely to be completely suitable for the job.
How to Maintain a Granite Composite Kitchen Sink
Be Consistent -
Cleaning regularly with hot (not boiling) soapy water and a soft cloth is a far more effective method than letting the dirt build up and carrying out an infrequent deep clean. Nip any dirt and stains in the bud by being consistent with your cleaning.
Check with Your Manufacturer -
Different sinks are built to withstand different things, so it’s best to check with your manufacturer about the best way to look after your sink. Some may be resistant to heat, others less so. If in doubt, be sure to check, it’s better to be safe than sorry.
Rinse and Dry After Each Use -
Doing this will save you time in the long run and help your composite sink to last for longer. Rinsing and drying your sink after every use will prevent unsightly water marks, limescale and other stains from appearing over time.
Use Harsh Chemicals -
While composite sinks are built to withstand dropped pans and crockery (or in Schock’s case, the power of a gunshot), they aren’t much good when it comes to surviving chemicals. Harsh chemicals can damage the colour and leave your sink looking far, far worse than before. Chemicals to avoid include ammonia, sodium hydroxide, hydrochloride and sulphuric acid. If in doubt, check with your manufacturer or stick to something that’s designed specifically for a composite sink.
Use Abrasive Materials -
When cleaning your sink, it’s important not to use anything abrasive. Steel wool and abrasive brushes will leave scratch marks. Instead, clean your sink with soft sponges to protect the exterior.
Leave Wet Sponges on The Sink -
We’re all guilty of this, but it’s important to be mindful of leaving wet sponges on your sink. If left for too long they’ll leave water marks or limescale deposits. Ultimately, this’ll mean more work for you in the long run.
Regular Cleaning and Upkeep
Regular cleaning is essential when it comes to keeping your composite kitchen sink in tip top condition. Homemade cleaners can be easily concocted, or there’s a variety of ready-made cleaning products out there if you’re not confident making your own.
Clean your composite sink after each use with hot soapy water and a soft sponge. Dry it thoroughly to prevent water spots, soap and mineral deposits. Cleaning and drying regularly will mean you’ll have to ‘deep clean’ far less often than you would otherwise.
Removing Limescale And Watermarks
In hard water areas limescale build up is a huge problem, which is why it’s essential to dry your sink after each use. If you fancy a workout as well as a clean sink, a combination of fairy liquid, a soft sponge and some serious elbow grease should do the trick. A 50% mix of water and white vinegar is another good option, although it’s essential not to leave the vinegar in contact with the surface of the sink for a sustained period.
If your biceps are good enough as they are and you don’t fancy putting your DIY hat on, the Astracast Composite Sink Cleaner is a great option. Inexpensive, and designed specifically for granite composite sinks, using the AstraClean once a week will remove and prevent limescale build up as well as grease, food and bacteria. Plus, there’s no need to phone any manufacturers (let’s all breathe a sigh of relief), as the AstraClean is compatible with all granite composite materials from all manufacturers.
Removing Deep Stains
No matter how careful we are, there’s still the possibility of deep stains, which can be a little trickier to remove. You can whip up a homemade concoction using household products - baking soda or white vinegar mixed with water will work well. Get scrubbing with a soft sponge and use soft bristle brushes to tackle the trickier bits, remembering to rinse and dry after cleaning.
However, if you’re unsure and concerned about damaging your sink with harsh products, you might want to consider purchasing something readymade. Back to our all-rounder, the Astracast Granite Kitchen Sink Cleaner. As well as tackling limescale and general day-to-day dirt, this nifty cleaner will remove deeper stains and marks too.
Whatever you use to tackle those deeper stains, it’s essential to rinse the sink thoroughly with hot water both before and after cleaning. Ensure it is dried thoroughly after use and it’ll soon be good as new with (relatively) little effort required on your part.
Even though they are higher maintenance than other kitchen sinks, granite composite sinks are a great choice thanks to their long-life, high durability and huge choice of colours. While they certainly withstand many stresses of modern life, they will start looking dull and discoloured if not taken care of. Getting into the habit of treating your sink with care will ensure it lasts for long time, requiring far less time and attention in the long run.
