Putting in a Kitchen Sink for Beginners
Upgrading the kitchen is often at the top of many homeowners' to-do lists. And one of the best places to start is by replacing an old, worn-out sink with a shiny new one. Installing a kitchen sink may sound difficult, but with the right preparation and tools, even total newbies can achieve a successful DIY installation.
In this beginner's guide, we will walk through the entire process of how to put in a kitchen sink , from choosing the right model to connecting the drainpipes and water lines. We'll share tips for removing the old sink, prepping the countertop, setting the new sink in place, and completing the minor adjustments needed for a perfect fit. Let's get started!
Types of Kitchen Sinks
Kitchen sinks come in a variety of styles to suit different spaces and needs:
- Top-Mount (Drop-in) - The most popular style, dropped into a pre-cut hole in the counter. Rim hides rough edges.
- Undermount - Mounted below the counter for a sleek, seamless look. Requires a specialty cutout.
- Farmhouse/Apron-Front - Exposed front face and vintage style. Goes well with rustic decor.
- Integral/One-Piece - Molded as part of a solid surface countertop for minimal seams.
This article focuses on the process for installing a standard stainless steel top-mount sink. But the basic preparation and plumbing steps apply to most sink varieties.
Preparing for Installation
Before you can install the new sink, you need to purchase one and get some essential supplies. You'll also need to disconnect and remove the old sink.
Gathering Materials and Tools
Here are the basic items you'll need:
- New kitchen sink (we recommend stainless steel or enamel)
- Drain pipes, drain tailpiece, P-trap, sink strainer
- Faucet (if needed)
- Plumber's putty, silicone caulk
- Wrenches, bucket, towels, flashlight
Selecting the Kitchen Sink
Choose a sink size and style that fits your countertop opening and matches your faucet, cabinetry, and decor. Stainless, enamel, quartz composite, and fireclay are popular options. Consider accessories like strainers, cutting boards, rinse grids, and more.
Preparing the Existing Sink Area
To access the sink base cabinet for installation, you need to:
- Turn off hot and cold water supply valves
- Disconnect and remove P-trap and drain tailpiece
- Detach supply lines, disposal, faucet, strainers, etc.
- Take out old sink by removing clips and caulk/sealant
Preparing the Countertop
Examine the existing countertop hole size and placement. Adjust to properly fit new sink:
- Expand opening if new sink is larger
- Fill gap if new sink is smaller
- Reposition for centered placement
Use a countersink bit to ease any rough edges. Clean and dry the area well.
Installing the New Sink
Now comes the fun part--putting in the shiny new sink! Carefully lower it into place and secure it firmly so you can connect the plumbing.
Preparing the Base Cabinet
Check that the cabinet is clean, level, and sturdy enough to hold the weight of a loaded sink. Make any repairs needed to ensure it can properly support the sink.
Setting the Sink in Place
Set the sink upside down on the cabinet. Apply silicone caulk around the edge of the hole. Then carefully flip the sink over, centering it in the hole. Press down firmly so the caulk makes a good seal.
Securing the Sink
From under the sink, install metal clinching clips (or wood blocks for some sinks) around the rim to secure it tightly against the underside of the countertop.
Connecting Drain Pipes
Attach the drain tailpiece, P-trap, strainer, and any extension pipes, using plumber's putty on the strainer threads. Securely hand-tighten all slip nuts and couplings.
Connecting Water Supply Lines
Attach flexible supply lines from the faucet to the water supply valves using adjustable pliers or wrenches. Use pipe tape on threads to prevent leaks.
Installing Specialty Kitchen Sinks
While basic drop-in sinks have straightforward installation, other varieties require some special considerations:
- Undermount - Clips secure to the underside of the stone/solid surface countertop.
- Farmhouse - Install support brackets to bear the weight of the exposed front.
- Integral - Built into the countertop requiring expert fabrication.
Consult specific guides for these specialty sink types before attempting installation.
Completing the Installation
You're in the home stretch! Just a few more steps to wrap up the installation and start using the sink.
Checking for Leaks
Turn on the water supply and look carefully under and around the sink for drips or leaks. Tighten any connections as needed to stop leaks.
Reinstalling Baseboards and Backsplash
If removed earlier, put back the cabinet baseboard trim pieces and replace any wall tiles or backsplash around the sink.
Caulking Around the Sink
Apply a smooth, neat bead of silicone caulk around the sink's rim where it meets the countertop. Wipe away any excess caulk with a wet rag.
Turning on Water Supply
Slowly turn on and test both hot and cold water supply valves. Check for leaks!
Installing Accessories
Attach any additional items like spray hoses, soap dispensers, filters, cutting boards, etc. according to the manufacturer's instructions.
Testing and Final Touches
Before enjoying your sparkling new sink, confirm everything is working properly.
Confirming Proper Drainage
Run water and check that the sink empties smoothly without any clogs or back-ups. Pour a bucket of water directly into the drain as an extra test.
Adjusting Water Flow
If needed, tweak the angle of the faucet neck and tighten nuts to adjust water pressure and temperature to your preferred flow.
Sealing Edges and Surfaces
Run a bead of silicone caulk along the seam where the sink meets the wall and allow to dry overnight. Use grout sealant on porcelain sinks.
Cleaning and First Use
Wash down the entire sink, faucet, walls and countertop before first use. Rinse dishes thoroughly as some sinks can retain odors at first.
Preventing Problems
To keep your new sink looking like new for years to come, be sure to:
- Use a protective grid, pad, or basin when washing dishes
- Avoid pouring excess oils/grease directly into the drain
- Clean debris from basket strainer regularly
- Spot clean surfaces using nonabrasive cleaners/sponges
Catch issues early and don't neglect basic maintenance for the longest lifespan.
