Kitchen & Bar Sinks: Drop-In

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 luxurious new countertops.

Not all Drop-In kitchen sinks require mounting hardware. If your kitchen sink does not come with mounting brackets, we recommend securing your sink with 100% silicone and expandable foam.

1. Flip sink upside down and trace the outside edge onto craft paper or cardboard. 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.

4. Always double check the sink for fit inside the hole before moving on.

5. If your sink does not come with mounting hardware, refer to bath sink drop-in installation instructions.

6. Before dropping your new sink into the countertop for the last time apply a thick bead of Sinkology antique brown or 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) for Copper Sinks.

7. Install hardware. Place the notched end of all bolts into the keyhole slots. See diagram 1. Lower the sink carefully into the countertop so the bolts enter without interference.

8. Turn the claws out 90 degrees so they will grasp the underside of the countertop. See diagram 2.

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

10. Some Sinkology copper sinks feature rear deck brackets that are designed for hardware with two claws per bolt. First claw closest to bracket bolt tip will sit against the underneath of the sink rim. Second claw will be used to grab underneath the countertop. See diagram 3.

11. Install drains.

12. For a professional look apply a thin bead of Sinkology antique brown or clear neutral cure 100% silicone around the rim.

13. For regular maintenance simply wash with gentle soap and water. For extra protection against water spotting, use Sinkology Copper Armor care kit (#SARMOR-201) or high quality carnauba wax. 

Kitchen & Bar Sinks: Undermount

Professional Installation Recommended

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 kitchen sink under-counter it makes wiping countertops easy and helps during kitchen clean up.

Sinkology undermount kitchen sinks do not include mounting hardware. We recommend providing your sink details to your countertop manufacturer for approved mounting hardware and method.

1. Flip sink upside down on a sheet of craft paper or cardboard and trace the outside rim of the sink. Select preferred countertop offset. See diagram 1. Measure the distance between the edge of the basin and the inside edge of the lip. Add a second line inside the first according to this measurement. Cut out the template along the second line.

2. Place the template onto the countertop and cut the hole into the countertop.

3. Use clear or Sinkology antique brown neutral cure 100% silicone (#SINSTALL-101) on the rim of the sink. Mount sink under the countertop using mounting hardware. Sinkology does not provide under mounting hardware due to the wide variety of mounting surfaces which require specific hardware. Contact your countertop manufacturer for specific mounting hardware.

4. Ensure sink is mounted flat against countertop on all sides, adjust hardware as needed.

5. Use plumbers putty to install the drain. Clean excess.

6. To complete your install we recommend applying a thin bead of Sinkology antique brown or clear neutral cure 100% silicone to any gaps between sink and countertop.

7. For regular maintenance simply wash with gentle soap and water. For extra protection against water spotting, use Sinkology Copper Armor care kit (#SARMOR-101) or high quality carnauba wax. 

Kitchen Farmhouse Sinks: Undermount

Professional Installation Recommended

Farmhouse kitchen sinks are the ultimate kitchen design element. Sinkology apron front kitchen sinks are designed to be highly functional yet make a bold statement. The apron front design and large spacious bowl make kitchen clean up more comfortable.

Most Sinkology farmhouse kitchen sinks can be installed as an undermount or drop-in. We recommend undermount installation with new granite or solid surface countertops.

Farmhouse sinks require extra installation steps, we recommend using professional tools and professional experience when installing farmhouse copper sinks. Occasionally the cabinet face front and countertop will be cut to accommodate apron front sinks. Undermount farmhouse sinks require additional support to hold the sink in place.

1. Flip sink upside down on a piece of craft paper or cardboard and trace the edge of the basin. Measure the distance between the edge of the basin and the inside edge of the lip. Add a second line inside the first according to this measurement. Cut on the second line to make your cut out template. The apron front is designed to extend past the front of the cabinet. Take this measurement before making any cuts. When you make your cut out measurements, accommodate the apron extending past the cabinet front. 

2. Cut the countertop and cabinet front to accommodate the sink basin using your cut out template.

3. Build a support ledge for your sink. Screw three lengths of 2×4’s (depends on cabinet width) along the back and both sides of the cabinet. The sink is fully supported when ¾” inch of the rim is supported on three sides. If additional support is needed four vertical 2×4 supports can be installed. See diagram 1.

4. Ensure top sink rim rests 1/8” inch below the top of cabinet frame when supported and in place.

5. Countertops will be placed directly on top of cabinet and sink. Farmhouse sink typically needs to be fully in place before countertop templating can begin.

6. Install the countertop. Apply a thin bead of Sinkology antique brown or clear neutral cure 100% silicone into any gaps between sink and countertop. See our Complete Silicone Installation Kit (#SINSTALL-101) for Copper Sinks.

7. For regular maintenance simply wash with gentle soap and water. For extra protection against water spotting, use Sinkology Copper Armor care kit (#SARMOR-201) or high quality carnauba wax.
