Top 5 Common Problems with Granite Composite Sinks and Solutions

June 13, 2023


Granite composite sinks are becoming increasingly popular among homeowners due to their durability and sleek appearance. However, like any other kitchen fixture, they come with their fair share of problems. In this article, we will highlight the top five common problems with granite composite sinks and provide solutions to help you get the most out of your investment.

Problem 1: Stains and Discoloration

Granite composite sinks can be quite porous, making them susceptible to stains and discoloration over time. One of the main culprits of staining is hard water, which can leave behind mineral deposits and cause discoloration. To avoid this, it is essential to clean your granite composite sink regularly using a mild detergent and a soft-bristled brush. Additionally, avoid leaving acidic substances such as lemon juice or vinegar on the sink's surface for extended periods.

Problem 2: Scratches and Scuffs

Granite composite sinks are relatively scratch-resistant, but they can still develop scratches and scuffs over time. These blemishes can be caused by heavy use, external force, or even metal utensils. To minimize scratching, always use a soft sponge or cloth when cleaning your sink. If you notice any scratches or scuffs, you can use a mild abrasive such as baking soda to gently buff them away.

Problem 3: Cracks and Chips

Cracks and chips are not uncommon in granite composite sinks, especially those that are installed incorrectly or subjected to heavy impact. While small cracks or chips may not be immediately noticeable, they can grow over time and cause further damage. To prevent this from happening, ensure that your sink is professionally installed and use a cutting board to avoid direct impact from heavy objects.

Problem 4: Water Pressure and Drain Issues

Water pressure and drain issues may arise if the sink's plumbing is not correctly installed. Low water pressure can make it challenging to properly rinse and clean your sink, while clogged drains can cause water to back up and overflow. If you are experiencing these problems, consider calling a professional plumber to assess and correct any plumbing issues.

Problem 5: Bad Odors

Finally, granite composite sinks can develop bad odors if not cleaned correctly or left damp for extended periods. These odors can be a significant source of discomfort in the kitchen. To eliminate bad smells, regularly clean your sink using a mild detergent or vinegar and baking soda mixture. Additionally, ensure that there is proper ventilation in the kitchen to prevent moisture buildup.


Granite composite sinks are a great addition to any kitchen, but they do require proper care and maintenance to perform optimally. By addressing the top five common problems highlighted in this article, you can ensure that your granite composite sink lasts for years to come. If you experience any significant issues, don't hesitate to seek professional assistance to get your sink back in top shape.
