Installing Your Granite Composite Sink

Each granite sink in the JOURNEY collection offers easy DIY installation with two mounting options: undermount or drop-in. Your granite sink will maintain its contemporary style and complete functionality regardless of which mounting option you prefer. 

Drop-in kitchen sinks are easy to install and are designed to install beautifully in a wide range of countertop surfaces. Sinkology drop-in kitchen sinks make DIY kitchen renovations effortless and impactful. Drop-in sinks can be used to replace an old sink or installed in new countertops.

Undermount kitchen sinks are recommended when installing new granite or solid surface countertops. Undermount installation adds a luxurious and professional look to kitchen design and maximizes countertop space. By installing your Sinkology granite kitchen sink under counter it makes wiping countertops easy and helps during kitchen clean up.

If you are unsure about which style is right for you or how to install your Sinkology kitchen sink, we recommend contacting a professional to assist with your installation.

Kitchen: Drop-In Sink Installation

1. Flip sink upside down and trace the outside edge onto craft paper or cardboard to make your own install template. Add a second line that is 1/2” inch inside that line. Cut out the traced template using the second line.

2. Position the template flat on the countertop and align with cabinet and plumbing connections.

3. Mark openings and cut the countertop. Always double check the sink for fit inside the hole before moving on.

4. Before dropping your new sink into the countertop for the last time apply a thick bead of Sinkology clear neutral cure 100% silicone around the hole on the countertop to form a water tight seal around the sink. See our Complete Silicone Installation Kit (#SINSTALL-101).

5. Install hardware. See diagrams.

6. Claws can be bent to accommodate larger or smaller gaps. Tighten evenly until all of the clamps grasp the underside of the countertop firmly and securely.

7. Install drains. (see full install guide for drain installation instructions)

8. For a professional look apply a thin bead of Sinkology clear neutral cure 100% silicone around the rim.

9. For regular maintenance simply wash with gentle soap and water.





Granite Sink Faucet Hole Knock-Out Instructions

Sinkology Granite Composite Kitchen Sinks (single and double-bowl) come 4 additional optional knock-outs to allow for a variety of faucet options.

Recommended Tools:

     • Eye + Ear Protection

     • Half-Round File

     • Center Punch

     • Hammer

1. Place the sink on a sturdy work table or area, support the outside rim of the sink with wood blocks. To strike the knockouts from the top, you will need the inside of the sink facing upright or out.

2. Align the pointed end of the center punch to the center of the knockout and strike with a hammer. This will push the knockout from the edge of the sink. Repeat this procedure to remove any additional knockouts.

3. Check the size of the knockout with your faucet. If additional room is needed, use a half-round file to increase the hole size until the faucet rests against the sink edge.
