How to Install a SoLuna Copper Bar or Prep Sink

The steps to installing a drop-in or undermount bar/prep sink are quite similar with just minor adjustments to how the sink attaches to the countertop. Here’s a detailed guide for how to install each type of bar and prep sink:

Installing a SoLuna Copper Drop-In (Top-Mount) Bar or Prep Sink

Materials/Tools Needed:

• Bar sink
• Silicone caulk
• Jigsaw or hole saw
• Tape measure
• Plumber's Putty
• Screws or sink clips (if required by manufacturer)
• Wrench or screwdriver
• Towel or rags

Steps:

• Measure and Mark the Cutout:
  • Place the sink upside down on the countertop in the desired location. Trace the outline of the sink’s lip with a pencil.
  • Inside this outline, mark a smaller cut line about 1/2 inch inside the traced line (this is to accommodate the lip of the sink).
• Cut the Countertop:
  • Use a jigsaw or hole saw to cut along the inner line you marked. Ensure you cut slowly and steadily for a smooth edge. For some materials like granite or quartz, you may need professional tools or help to make precise cuts.
• Prepare the Sink Mount:
  • Ensure that the cutout edge is clean and smooth, as the sink needs to fit flush with the top of the countertop. Any rough spots may need to be sanded or smoothed.
• Test Fit the Sink:
  • Insert the sink into the hole to make sure it fits properly. Adjust the cutout if necessary.
• Apply Caulk:
  • Apply a bead of silicone caulk around the underside of the sink’s lip to ensure a watertight seal when the sink is installed.
• Install the Sink:
  • Gently lower the sink into the cutout, pressing it down to create a tight seal with the caulk.
• Connect Plumbing:
  • Install the faucet, drain, and any other necessary plumbing connections. Use plumber’s putty where needed to create a watertight seal for the drain.
• Clean Up:
  • Wipe away any excess caulk from around the sink with a damp cloth.
• Wax Sink: 
  • You can wax your copper sink periodically to help delay tarnishing and oxidation.  We recommend "Renaissance Wax" or "Howard Wax-It-All".

Installing a SoLuna Copper Undermount Bar or Prep Sink

Materials/Tools Needed:

• Bar sink
• Silicone caulk
• Jigsaw or hole saw
• Drill with appropriate bit
• Sink mounting clips (if required by manufacturer)
• Tape measure
• Plumber’s Putty
• Epoxy or adhesive (depending on the countertop material)

Steps:

• Measure and Mark the Cutout:
  • Place the sink upside down on the countertop to mark its position. 
  • Mark the cut line inside the traced outline, typically about 1/2 inch inside to account for the sink lip being attached underneath.
• Cut the Countertop:
  • Cut along the marked line using a jigsaw or hole saw, taking care to make a smooth edge. This step may require professional tools for hard materials like granite or quartz.
• Prepare the Sink Mount:
  • Ensure that the cutout edge is clean and smooth, as the sink will be attached to the underside of the countertop. Any rough spots may need to be sanded or smoothed.
• Attach Mounting Clips:
  • Depending on your countertop material, either epoxy the mounting clips to the underside of the countertop or drill small holes to screw in the clips.
• Apply Sealant:
  • Run a continuous bead of silicone caulk around the top edge of the sink where it will meet the underside of the countertop.
• Position the Sink:
  • Position the sink under the countertop and hold it in place. You may need an extra set of hands or support to hold the sink while attaching the clips.
• Secure the Sink:
  • Attach the mounting clips and tighten them as per the manufacturer’s instructions. This will hold the sink firmly against the underside of the countertop.
• Let the Caulk Set:
  • Allow the silicone to cure, usually for 24 hours, before attaching any plumbing. This ensures a watertight seal.
• Connect Plumbing:
  • Attach the faucet, drain, and water supply lines. Use plumber’s putty to create a watertight seal for the drain.
• Clean Up:
  • Wipe off any excess caulk and check all plumbing connections for leaks.
• Wax Sink: 
  • You can wax your copper sink periodically to help delay tarnishing and oxidation.  We recommend "Renaissance Wax" or "Howard Wax-It-All".

Important Considerations for Both Types:

• Countertop Material:
  • If your countertop is made of stone (like granite or quartz), you may need professional assistance for cutting the hole and securing the undermount sink.
• Sink Size and Placement:
  • Since bar sinks are typically smaller than standard sinks, ensure the placement is optimized for functionality and ease of use.
• Faucet Configuration:
  • Plan for the faucet location and the size of the hole if you’re installing a new faucet along with the sink.

By following these steps and ensuring proper sealing and fitting, you’ll have a securely installed drop-in or undermount bar or prep sink.
