What Is a Farmhouse Sink?
A farmhouse sink is also called an apron-front sink. It has a big front panel that sticks out a little. These sinks are deep and wide. They are great for washing big pots and pans. Many people like the look and style of farmhouse sinks.
Why Install Without Removing the Countertop?
- It saves time.
- It costs less money.
- It avoids damage to your countertop.
- It is easier for beginners.
Removing the countertop takes skill. It can break the surface. By keeping the countertop, the job is safer and quicker.
Tools and Materials You Will Need
Before you start, gather these tools and materials:
- Farmhouse sink (make sure it fits your cabinet)
- Jigsaw or hole saw
- Measuring tape
- Pencil or marker
- Silicone sealant
- Plumber’s putty
- Screwdriver
- Adjustable wrench
- Bucket (for water)
- Rags or cloths
- Pipe wrench (optional)
Step 1: Measure Your Sink and Cabinet
First, measure the farmhouse sink’s dimensions. You need to know its width, length, and depth. Next, measure the cabinet where the sink will go. Check if the sink can fit inside the cabinet opening.
Farmhouse sinks are usually bigger. You might need to remove some wood inside the cabinet. But you don’t have to remove the countertop. Just make sure the sink fits in the space under the counter.
Step 2: Mark the Cut Line on the Countertop
Place the sink upside down on the countertop where you want it. Use a pencil to trace the sink’s edge on the countertop. This line shows where you will cut.
Remember: You only need to cut a small part of the countertop. This cut lets the front part of the sink come through and sit properly.
Step 3: Cut the Countertop
Put on safety glasses. Use a jigsaw to carefully cut along your pencil line. Take your time. Cutting slowly helps avoid mistakes.
If you have a hole saw, you can use it to start the cut. This tool makes a small hole to put the jigsaw blade inside.
After cutting, clean the edges with sandpaper. Make the cut smooth and even.

Step 4: Remove the Old Sink
Turn off the water supply under the sink. Use a wrench to disconnect the water pipes and drain pipes. Put a bucket under the pipes to catch any water.
Remove any clips or screws holding the old sink. Then lift the sink out carefully. Clean the area to remove old sealant or dirt.
Step 5: Prepare the Farmhouse Sink for Installation
Apply silicone sealant along the edge of the sink’s rim. This seal keeps water from leaking under the sink.
If your sink has mounting clips, attach them now. These clips will help hold the sink in place.
Step 6: Place the Farmhouse Sink
Lift the sink and slide the front apron through the cut you made. The sink’s front should now stick out from the cabinet.
Lower the sink gently into place. The rim should sit on the countertop surface. Adjust the sink until it fits well and looks straight.
Step 7: Secure the Sink
Use the mounting clips under the sink to hold it tight. Screw the clips to the cabinet frame. Make sure the sink does not move.
Wipe off any extra silicone sealant with a cloth.

Step 8: Connect the Plumbing
Reconnect the water supply lines to the faucet. Tighten the nuts with an adjustable wrench.
Attach the drain pipes to the sink’s drain. Use plumber’s putty to seal the drain opening before placing the drain assembly.
Check all connections for leaks. Turn on the water supply and watch carefully.
Step 9: Final Checks
- Make sure the sink is level.
- Check that the front apron sits flush with the cabinet.
- Look for any gaps between sink and countertop.
- Seal small gaps with extra silicone if needed.
Clean your new sink and countertop. Your installation is now complete!
