Gathering the Essential Tools
Before embarking on this project, ensure you have the following tools at your disposal:
- Measuring tape
- Level
- Pencil or marker
- Jigsaw
- Sandpaper or sanding block
- Caulk gun
- Plumber’s putty
- Silicone caulk
- Wrench
- Pliers
Preparing the Granite Countertop
1. Measure and Mark: Using a measuring tape and pencil, mark the outline of the sink on the underside of the granite countertop. Use a level to ensure the outline is perfectly horizontal.
2. Cut the Granite: Carefully cut along the marked outline using a jigsaw. Sand the edges of the cutout to remove any rough edges.
3. Apply Plumber’s Putty: Roll out a thin bead of plumber’s putty around the edges of the granite cutout. This will create a watertight seal between the sink and the countertop.
Installing the Undermount Sink
1. Position the Sink: Carefully place the undermount sink into the cutout in the granite countertop. Ensure that the sink is level and centered.
2. Secure the Sink: Use the supplied mounting brackets or clips to secure the sink to the underside of the countertop. Tighten the screws or bolts securely.
Connecting the Plumbing
1. Attach Drain Assembly: Connect the drain assembly to the bottom of the sink and tighten the nuts. Apply plumber’s putty or silicone caulk to the threads for a watertight seal.
2. Connect Water Supply Lines: Attach the water supply lines to the hot and cold water valves under the sink. Use a wrench to tighten the connections.
Sealing the Edges
1. Apply Silicone Caulk: Apply a generous bead of silicone caulk around the perimeter of the sink, where it meets the granite countertop. Tool the caulk with a wet finger or caulk finishing tool to create a smooth, watertight seal.
2. Remove Excess Caulk: Use a damp cloth or paper towels to wipe away any excess caulk before it dries. Allow the caulk to cure completely according to the manufacturer’s instructions.
Finishing Touches
1. Install Faucet: Install the faucet on the countertop and connect the supply lines. Tighten the nuts and bolts securely.
2. Check for Leaks: Turn on the water supply and check for any leaks around the sink and plumbing connections. Tighten or adjust as necessary.
