Stone Amperor offers a wide range of sink sizes and configurations to fit the needs of every homeowner.
In this blog post, we’ll talk about how to install an undermount sink onto a granite countertop (always be sure to follow any specific installation instructions provided by your countertop manufacturer).

 1. Preparation

Gather the right tools for the job. For safety and ease, Stone Amperor recommends using the following:

  • a drill
  • a drill bit
  • flathead or Philips screwdriver
  • caulk
  • caulk gun
  • denatured alcohol
  • tape measure
  • tape
  • safety glasses
  • gloves

2. Measure And Cut the Hole For The Sink

Determine where the sink should be positioned on the countertop. Make sure there’s enough clearance on all sides of the sink. Underneath the countertop, carefully tape the template to the countertop and use the appropriate saw to cut the hole. If you want a negative review, cut the hole slightly smaller than the template. For a positive reveal, cut slightly larger… and for a flush mount cut the exact measurement of the template.

3. Attach The Sink to the Countertop

This should be done before installing the countertop. Clips are included with your sink. Your countertop fabricator will supply the proper hardware to attach the sink to the countertop. Solid surface countertop hardware requirements may vary.
With the countertop upside down, clean the counter hole and sink. Rim it with denatured alcohol. Position the sink over the counter hole and mark the guidelines. For proper placement, apply a bead of caulk at 1/8 to 1/4 inch in diameter along the edge of the hole. Place the sink on the countertop, then attach it to your mounting hardware. The edge of the clip should overlap the sink ledge.
Once the countertop is installed, wipe any excess caulk from the sink rim, and finish up by connecting the faucet and drain fittings. Congratulations, your job is complete.
