Average Kitchen Sink Replacement Cost in 2026
The national average kitchen sink replacement cost in 2026 runs $380 to $1,400, with most homeowners paying $700 to $900 for a mid-range sink with standard labour. This total includes removal of the old sink, the new sink, all hardware and fittings, and professional installation.
The sink itself accounts for $150 to $750 of that total. According to Fixr, the average job takes 1 to 3 hours for a straightforward drop-in swap, with plumbing modifications significantly raising costs. NearbyHunt quote data from 2025 shows homeowners who collected three or more quotes saved an average of $280 compared to those who accepted the first bid.
I've replaced over 280 kitchen sinks in 18 years. The number one budgeting mistake homeowners make is forgetting to factor in supply lines, a drain assembly, and sometimes a p-trap replacement. In Dallas, a complete kitchen sink replacement rarely comes in under $500 when you add everything up.
Kitchen Sink Cost by Material
The material you choose has the single biggest impact on your upfront sink cost. Stainless steel is the most affordable and widely installed option, while copper and fireclay sit at the premium end. Here is how 2026 sink prices break down by material:
| Material | Sink Cost (Material Only) | Installed Cost Range | Notes |
| Stainless Steel | $100 to $600 | $300 to $1,200 | Most popular; durable, lightweight, easy to clean |
| Porcelain/Ceramic | $150 to $500 | $350 to $1,100 | Scratch-resistant finish; heavy |
| Cast Iron | $200 to $900 | $400 to $1,600 | Very heavy; requires cabinet reinforcement |
| Composite Granite | $200 to $700 | $400 to $1,400 | Scratch and heat resistant; mid-range price |
| Fireclay | $300 to $900 | $500 to $1,700 | Durable, farmhouse-style favorite |
| Copper | $400 to $1,200 | $600 to $2,000 | Antimicrobial; develops patina over time |
| Acrylic/Plastic | $75 to $250 | $250 to $800 | Budget option; less durable long-term |
Stainless steel remains the dominant choice: lightweight, corrosion-resistant, and available from $100 to $600. Cast iron and fireclay sinks require additional cabinet reinforcement due to their weight, adding $100 to $300 to the total project cost.

Kitchen Sink Installation Labor Costs
Labor is the second major cost variable. According to the Plumbing-Heating-Cooling Contractors Association (PHCC), plumber hourly rates in 2026 range from $50 in lower-cost rural markets to $200 per hour in high-demand metro areas. For a full breakdown, see our guide on plumbing costs.
Here is what to expect for labor on common sink installation scenarios:
| Job Type | Estimated Labor Time | Labor Cost Range |
| Drop-in sink swap (same size) | 1 to 2 hours | $75 to $400 |
| Undermount sink replacement | 2 to 3 hours | $150 to $600 |
| Farmhouse/apron sink install | 3 to 5 hours | $250 to $900 |
| New sink with plumbing reroute | 4 to 8 hours | $400 to $1,600 |
| Emergency or after-hours install | Varies | 1.5x to 3x standard rate |
Old sink removal adds $20 to $300, depending on how it was installed. Always confirm whether the quote includes removal and disposal, as some contractors charge separately for them.
Drop-in sinks take me about 90 minutes on a clean swap where nothing else changes. Undermount sinks are a different story because the countertop clips and adhesive take time to cut and re-seal properly. I've seen homeowners save money by buying the sink themselves online, which is fine, but make sure the sink dimensions match your existing cutout exactly before I show up.
Drop-In vs. Undermount vs. Farmhouse Sink Costs
The mounting style of your new sink significantly affects both the sink price and the installation labor required.
Drop-in sinks (also called top-mount) sit on top of the countertop cutout and clip from below. No countertop modification is typically required, making them the fastest and least expensive option. Total installed cost runs $300 to $900 on average.
Undermount sinks attach to the underside of the countertop. Installation is more involved because the plumber must secure the sink with clips and silicone adhesive, and the countertop edge must be sealed. Total installed cost runs $500 to $1,400 on average. For more on plumbing challenges during this type of work, see our guide on common plumbing problems.
Farmhouse sinks (apron-front) require the most labor-intensive installation. The cabinet face must be modified to accommodate the exposed apron, and the sink's weight often requires cabinet reinforcement. Total installed cost runs $700 to $2,200 on average.

Factors That Affect Kitchen Sink Replacement Cost
Several variables beyond sink price and labor will influence your final total.
Plumbing modifications represent the largest potential cost addition. If your new sink needs relocated drain lines or a different faucet configuration, expect to pay $100 to $1,800 in additional plumbing work. Learn more about how plumbing works to understand what changes may be required.
P-trap replacement is a routine part of many sink swaps. A worn or corroded p-trap costs $15 to $75 in parts plus 30 to 60 minutes of labor. See our guide on how to replace a p-trap if you want to handle this yourself.
Faucet installation is often bundled with sink replacement. Adding a new faucet increases total cost by $80 to $600 depending on quality and hole drilling requirements. The combined cost to install a kitchen sink and faucet together runs $600 to $2,000 according to Bob Vila's 2026 data.
Shutoff valve condition is another inspection point. Old or corroded shutoff valves should be replaced at the same time to prevent future leaks at a cost of $75 to $200 installed. Our guide on installing a shutoff valve covers this in detail.
Geographic location creates meaningful cost differences. Plumbers in San Francisco, New York, and Seattle charge 40 to 80 percent more than plumbers in rural Midwest or Southern markets, with coastal metro projects averaging $950 versus $620 in lower-cost regions.
The call I get most often is someone who bought an undermount sink online to swap for their old drop-in. It almost never goes smoothly. The cutout is usually the wrong size, and laminate countertops can't be properly sealed for an undermount. Call your plumber before buying the sink.

DIY vs. Professional Kitchen Sink Installation
A basic drop-in sink swap is within reach for an experienced DIYer, but undermount, farmhouse, and any project requiring plumbing modifications should be left to licensed professionals. DIY cost savings on a straightforward replacement can reach $150 to $400 in labor, but mistakes can lead to water damage and mold remediation costs that far exceed the savings. Our guide on plumbing DIY projects covers which tasks are safe for homeowners.
Hiring a licensed plumber ensures the work meets local code, is covered by liability insurance, and includes a workmanship warranty. According to the NAHB, improperly installed kitchen plumbing is one of the leading causes of interior water damage claims.

I fix DIY sink replacements every month. The most common issues are supply lines that are not fully tightened and undermount sinks that separate from the countertop within 6 months. In over 2,400 jobs, I've never had a callback for a leaking supply line because I pressure-test every connection before leaving.
What to Expect During a Kitchen Sink Replacement
Most kitchen sink replacements take 2 to 4 hours. Your plumber will shut off the supply valves, disconnect supply lines and the drain, and remove the old sink. The new sink is dry-fitted to confirm cutout dimensions before supply lines and the p-trap are connected. A pressure test checks every fitting before the plumber leaves. For general plumbing background, our all about plumbing guide is a useful reference.

Conclusion
Kitchen sink replacement costs in 2026 range from $380 for a basic drop-in swap to $2,200 or more for a farmhouse installation with plumbing modifications. Material, mounting style, local labor rates, and plumbing changes are the four variables that drive your final cost. Getting three or more quotes and confirming what each includes is the most reliable way to stay within budget. For related guidance, see our overviews of plumbing costs and common plumbing problems.
