Installing a sink into a solid surface countertop, like quartz or Corian, requires cutting a precise hole to accommodate the sink. While challenging, with proper planning and tools, DIYers can create a professional-looking countertop and sink.


Solid surface countertops like quartz and Corian are popular options for kitchen and bathroom remodels due to their durability, seamless appearance, and easy maintenance. Cutting out holes for sinks requires specialized tools and techniques to get a clean, precise cutout that allows the sink to drop in properly. With some preparation and patience, homeowners can cut their own sink holes and install beautiful, functional solid surface countertops.

Benefits of Solid Surface Countertops

Before diving into the sink cutout process, it’s helpful to understand why solid surface is an excellent countertop choice:

  • Seamless look: The material can be fabricated into one continuous surface with no seams, giving a smooth, streamlined appearance.
  • Heat and scratch resistant: Solid surface stands up well to daily wear and tear, especially in busy kitchens.
  • Non-porous: The material won’t harbor bacteria or moisture. Simple cleaning keeps it hygienic.
  • Design flexibility: Solid surface comes in a wide range of colors and patterns to suit any decor. Custom edging and cutouts add style.
  • DIY-friendly: Homeowners with DIY skills can fabricate and install solid surface countertops and cutouts themselves.

Planning the Sink Cutout

Careful planning ensures proper sink placement within the countertop. When laying out the sink opening, keep these tips in mind:

  • Check the sink dimensions. Account for any overflow, faucet holes or backsplash clearance.
  • Follow the sink manufacturer’s recommendations for cutout size. This may be larger than the actual sink.
  • Allow room behind the sink for plumbing and sink clips, usually about 1-2 inches.
  • Position sinks near or at edges and corners for drainage.
  • For multiple sinks, allow proper counter space between cutouts.
  • Use templates to outline the cutout area before cutting.

Tools and Materials Needed

Cutting solid surface requires specialized power tools to get clean cuts. You’ll need:

  • Circular saw with diamond blade for straight cuts
  • Jigsaw with diamond blade for curves and corners
  • Router with diamond bits for edge profiling
  • Drill and hole saw set for faucet holes
  • Eye and ear protection, masks, and gloves for safety
  • Clamps and straightedge to guide cuts
  • Templates and markers to outline cuts
  • Mineral spirits and rags for cleaning cuts
  • Silicone adhesive to install sink

Step-by-Step Cutout Process

Once you’ve planned the layout and gathered supplies, follow these steps:

1. Mark the Sink Cutout Area

Use the sink template to trace the cutout area with a permanent marker. Check dimensions and placement.

2. Drill out Faucet Holes

Drill holes for the faucet and soap dispenser using a hole saw. Go slowly to avoid cracks.

3. Make Straight Cuts

Clamp a straightedge as a guide. Use a circular saw with diamond blade to make straight cuts first.

4. Cut Out Corners and Curves

Use a jigsaw with diamond blade to trim out corners and any curved sections. Work slowly.

5. Smooth and Clean Cut Edges

Use a router with diamond bit to smooth and shape the cutout edges. Wipe clean with mineral spirits.

6. Test Fit the Sink

Carefully set the sink in place and check the fit. Make any adjustments needed with the router.

7. Secure the Sink

Apply silicone adhesive around the sink edge. Place sink in cutout, pressing firmly in place. Allow adhesive to cure fully.

8. Connect Plumbing and Accessories

Attach drain pipes, supply lines, and accessories like soap dispensers. Caulk around edges if needed.

Tips for Success

Follow these tips to get a perfect solid surface sink cutout:

  • Take your time – rushing can lead to cracks and mistakes.
  • Keep cuts inside the layout lines – you can always trim more, but can’t add back.
  • Support the cutout area to prevent cracking while cutting.
  • Make small final trims and adjustments after test fitting the sink.
  • Follow all manufacturer instructions for adhesives, caulking, plumbing connections, etc.

With careful planning and use of the proper tools and techniques, DIYers can achieve beautifully installed solid surface countertops with professional-looking sink cutouts. The investment of time and care will be well worth it every time the smooth, seamless countertop is put to use.
