Replace Your Undermount Kitchen Sink Without Hassles

Is your undermount kitchen sink looking worse for wear? Faded finishes, stubborn stains, chips and cracks can make even washing dishes a chore. Replacing an aging undermount sink can refresh the look of your kitchen and make daily use much easier. With some preparation and care, you can swap out that old sink without damaging your countertops or breaking the bank.

From determining when it's time for a new one to prepping your workspace, removing old hardware and safely installing a fresh sink, we've got you covered. Follow these tips and you'll be washing dishes in style in no time.

Determine If Replacing the Sink is Necessary

Undermount sinks see heavy usage day in and day out. Over time, chips, stains, and general wear and tear can take their toll. Before deciding on replacement, determine if your current sink simply needs some TLC to restore its function.

Signs its time for a new undermount kitchen sink

An undermount sink with minor damage may still be salvageable. But if you notice any of the following, a new sink is likely your best bet:

• Deep stains that won't scrub out
• Large chips, cracks, or missing chunks of material
• Corrosion visible underneath or around drain
• Faucet no longer functions properly despite repairs
• Sink basin warped, no longer drains smoothly

When repairs or cleaning no longer work

Before deciding to replace rather than repair, attempt mending chips or refinishing stained areas first. Use etching cream and soap scum removers to revive finishes. If stains remain or cracks continue spreading, replacement will be the wiser route.

Benefits of getting a new undermount sink

Beyond cosmetic fixes, a new undermount sink offers practical bonuses:

• Improved functionality and drainage
• Updated look for a kitchen makeover
• Latest features like integrated accessories
• Better hygiene for food preparation
• Increased ease cleaning and maintenance

What You Need to Know Before Replacing Sink

While a straightforward task for professionals, undermount sink replacement poses risks for DIYers. Assess your skills realistically before getting started.

Risks of damaging countertop

Because undermount sinks are installed from below, they rely on strong sealing to keep from detaching. Built-up sealant bonds create resistance when removing old hardware. Attempting to break this seal risks cracking your countertop if not done properly.

Using professionals vs DIY

Those experienced in sink replacement may DIY safely. But for novices, hiring a plumbing pro pays off by preventing costly granite damages. Get quotes before deciding.

Measuring existing sink & cabinet

Since undermount sinks depend on the counter opening, compatibility matters. Before selecting a model, measure your existing sink and cabinet cutout width/length. This ensures proper sizing.

Prepping for Undermount Sink Replacement

Proper prep work lets you remove and install a new undermount sink smoothly. Follow these preparatory steps first.

Inspecting Current Set-up

Begin by scrutinizing your current configuration. This helps you disconnect fixtures methodically later.

• Check conditions of sink basin, faucet, supply lines and drainage
• Ensure countertop is free from deep scratches or flaws
• Locate shut off valves for water supply

Preparing the Work Area

Protect surrounding surfaces from water drips or spills ahead of time.

• Cover flooring with tarps
• Tape plastic sheets over backsplash
• Have clean up rags and buckets ready
• Clear out under-cabinet contents

Turning Off Water & Draining

Prevent leaks by shutting off water valves and emptying pipe lines first.

• Turn OFF supply valves located under sink or nearby
• Switch on faucet to drain leftover water
• Leave faucet OPEN to depressurize plumbing

Removing the Existing Undermount Sink

With prep work complete, it's time to detach and lift out the old undermount sink. Take care not to crack your countertops during this process.

Disconnecting Fixtures

Methodically detach the drain pipes, supply lines, and mounting attachments.

• Unscrew drain pipe from sink tailpiece and P-trap
• Unfasten supply lines from shut off valves & faucet
• Remove mounting clips or brackets from beneath

Lifting Out Old Sink

With hardware disconnected, gently lift out the sink. Beware of strongly adhered sealant.

• Cut through caulk beads with utility knife where needed
• Place protective boards beneath sink edges
• Slowly lift upwards, asking helper to support weight
• Set old sink aside and scrape away old caulk entirely

Installing New Undermount Kitchen Sink

With the old sink removed, it's time to safely install your shiny new upgrade. Refer to manufacturer instructions as needed through this process.

Preparing the Base Cabinet

Get your cabinet ready for the new undermount sink.

• Check measurements of countertop hole & cabinet width
• Adjust/reattach any plumbing as needed
• Use painter's tape to prevent scratching granite

Lowering New Sink In Place

Gently lower your new sink into the opening.

• Align sink evenly with countertop hole
• Hand tighten mounting clips/brackets
• Ensure sink rim makes full contact with tape

Connecting Plumbing & Caulking

Securely reconnect and seal your new installation.

• Attach supply lines to faucet & shut off valves
• Tighten drain pipe joints with previous configuration
• Apply steady silicone caulk beads around sink edge

Finishing Touches

With assembly complete, finish up by testing and protecting your work.

• Check all joints for leaks and drips
• Wipe away excess caulk for clean finish
• Leave tape around sink edges for 1-2 days

Learn how to maintain and care for your newly installed sink to keep it looking like new for years of heavy use.

• Allow silicone caulk to fully cure for 24-48 hours before use
• Use non-abrasive cleaners and soft sponges only
• Avoid placing extremely hot pans directly in basin
• Clean disposal blades regularly to prevent jams
• Consider water filtration system to reduce mineral spots

With proper care and cleaning habits, your fresh undermount sink should provide flawless function and beauty for everyday use. No more struggling with stubborn stains or embarrassing chips and cracks.
