Installing a sink with granite countertop


Granite has long been a favorite material for kitchen countertop installations. Granite is tougher and durable than Formica and other options. It also stands up well to wear and tear and will last for years to come. As a hard material, it is even scratch-resistant and easy to maintain and clean. Granite resists heat and seamlessly blends in with any kitchen décor or style. Whether working with a professional installer or going the DIY route, installing a sink with granite countertop requires several steps that must be followed and performed to a tee.

Step 1

The first step in installing a sink with a granite countertop is to measure the sink’s opening. The sink usually takes up around 33″ by 22″ inches from the outside rims. Jot these dimensions down and head over to your local home improvement center. You can speak to a sales professional and inquire about sinks that are top-mounted or self-rimmed. Remember, your granite countertop is already installed with the opening cut and ready.

Step 2

After buying your sink, position it near the granite countertop. Add polyurethane sealant to the lip under the edges of the sink. Remember that unsealed stone tends to absorb stains easier but may be challenging to clean at times. Check the type of counter you have and make sure the sealants and caulking will correlate with its stone type. You can ask a friend or loved one to hold the sink on one side while you apply the polyethurane as needed.

Apply the sealant, then flip the sink back over and position it over the countertop. You can wait a few seconds for the sealant to dry then move on to step three.

Step 3

Position the sink as needed and carefully lower it into the opening. Make sure not to chip or damage the granite when centering and placing the sink. Also, attach the sink to the right plumbing components under the cabinet. Follow the manufacturer’s instructions to make sure all components are properly connected. Caulk around all the connections to secure waterproof seals. This is important in preventing leaks if something gets stuck in the sink’s disposer or backflow is present.

Step 4

You also need to place silicone caulk under the cabinets on the sink’s rims. This is below the counter where it connects to the unit. If the granite is darker in appearance, use a lighter caulk for a more professional and aesthetic appearance. Apply the right amount of caulking, as described in the manufacturer’s instructions.

Step 5

The final step in the process is to apply pressure on the sink with your hands. Concentrate on applying pressure to and around the edges to secure an airtight seal. Let the sealant and caulk dry in place around the sink. Use a cloth to remove any sealant or caul that is showing around the top edges of the sink.
