Factors That Affect Cost
Sink Type
Drop-in sinks are cheapest to install because they sit in an existing cutout. Undermount sinks require countertop modifications. Farmhouse sinks need cabinet modifications.
Same Location vs New
Replacing a sink in the same spot costs $200-$600 for labor. Installing a sink in a new location requires running new supply and drain lines — $1,500+ in plumbing work.
Countertop Modifications
If the new sink is a different size or style, the countertop may need to be cut or replaced. Granite countertop modifications cost $200-$500.
Faucet and Disposal
A new faucet adds $150-$400. Adding or replacing a garbage disposal adds $150-$500. These are often done during sink replacement for convenience.
Plumbing Condition
Old or corroded drain pipes, outdated shut-off valves, or galvanized supply lines may need to be replaced during the job, adding $100-$400.
When to Call a Professional
Call a plumber for undermount sink installations, any job requiring new plumbing lines, or when dealing with old corroded pipes. A drop-in sink swap is manageable as a DIY project for handy homeowners.
