You’re looking at $611 to $914 to install a bathroom sink, nationally. That’s the all-in price: sink, labor, supplies, removal of the old one, and hauling the debris away. But the real number depends on where you live, what sink you pick, and whether your plumbing fights back.
Here’s what actually drives the bill.
What You’re Paying For
The sink itself runs $117 to $293. A basic drop-in from Home Depot might be $80; a nice undermount or vessel sink pushes past $250. Labor is the biggest chunk: $333 to $423 for installation. Job supplies—plumber’s putty, silicone caulk, maybe new supply lines—add $28 to $33. Want the old sink gone? Add $85 to $108 for removal, and $48 to $57 for debris disposal.
So if you’re swapping a cracked sink for a similar model, expect around $600 to $750 total. If you’re upgrading to a pedestal or vessel sink with new faucets and drain hardware, you’re closer to $900.
City by City: Where You Live Matters
Labor rates vary wildly. Here’s the real spread across 20 major metros:
| City | Typical Range (per sink) |
|---|---|
| New York, NY | $812 – $1,179 |
| San Jose, CA | $767 – $1,120 |
| San Francisco, CA | $767 – $1,120 |
| Seattle, WA | $745 – $1,091 |
| Chicago, IL | $723 – $1,061 |
| Boston, MA | $723 – $1,061 |
| Los Angeles, CA | $700 – $1,032 |
| Philadelphia, PA | $678 – $1,002 |
| San Diego, CA | $678 – $1,002 |
| Minneapolis, MN | $678 – $1,002 |
| Columbus, OH | $598 – $896 |
| Phoenix, AZ | $589 – $885 |
| Denver, CO | $589 – $885 |
| Atlanta, GA | $566 – $855 |
| Houston, TX | $557 – $843 |
| Dallas, TX | $557 – $843 |
| Jacksonville, FL | $553 – $838 |
| Miami, FL | $553 – $838 |
| San Antonio, TX | $548 – $832 |
| Austin, TX | $544 – $826 |
Notice the gap: a sink swap in Austin might run $544, but in New York you’re easily $812—and that’s before any surprises. The difference is mostly labor rates and overhead.
What Homeowners Actually Report Paying
Real people on Reddit tell a consistent story. A homeowner in Mississauga was quoted $400 to replace a cracked undermount sink. The consensus: that’s a good deal, especially if it includes the vanity. Another poster got a quote for $1,000 to install a toilet, bathroom sink, and kitchen sink—and the top comment said “take it quick.” Professionals said they’d expect to pay that much, and DIYers admitted they now understand why plumbers charge what they do.
The lesson: $400 for a single sink replacement is fair in most markets. If you’re paying $1,200 for just one sink, something’s off—unless you’re in Manhattan with a complex undermount install and old pipes.
The Gotchas That Blow Up the Price
Homeowners warn about a few common surprises:
- Old shut-off valves that won’t turn or leak. If the plumber has to replace them, add $50–$150.
- Countertop damage during undermount sink removal. One Redditor noted you might have to remove the countertop entirely—a sketchy job that adds cost.
- Custom fabrication if your new sink doesn’t fit the existing hole. Cutting a bigger opening in granite or quartz runs $200–$400.
- Condominium restrictions—if you need to shut off water to the whole building, that’s a scheduling nightmare and a premium on labor.
How to Save Money and Get a Fair Quote
1. Get three quotes. That’s the standard advice, and it works. The plumber who quoted $1,200 for a customer-supplied sink was probably giving a “I don’t want this job” price. Another pro might do it for $500.
2. Consider a handyman. Multiple Redditors point out that replacing a drop-in sink isn’t licensed-plumber work. A reputable handyman can do it for $200–$350 in labor. For an undermount sink, you might still want a pro, but get a handyman quote first.
3. Buy the sink yourself. Markups on fixtures can be 30–50%. Buy your sink and faucet online or at a big-box store, then pay someone for labor only. Just make sure you know the return policy.
4. DIY if you’re handy. A drop-in sink replacement is one of the easier plumbing jobs. Tools: a basin wrench, putty knife, plumber’s putty, and a new supply line ($20–$40 total). Watch a few videos. If you mess up, you’ll call a plumber anyway—but many homeowners save $300–$500 doing it themselves.
5. Bundle jobs. If you need a toilet and kitchen sink too, get a single quote. That Redditor’s $1,000 quote for three fixtures is actually reasonable—about $333 per fixture. Plumbers often discount multiple jobs in one trip.
FAQ
How much does it cost for a plumber to install a bathroom sink?
Nationally, $333–$423 for labor alone. Add the sink ($117–$293) and supplies ($28–$33), and you’re at $478–$749 for a basic install. Removal and disposal push it to $611–$914.
Can a handyman install a new sink?
Yes, for a drop-in or vessel sink. Many homeowners do it themselves. For an undermount sink that requires countertop work, a licensed plumber or countertop specialist is safer.
Is it a big job to change a bathroom sink?
For a drop-in sink, it’s a 1–2 hour job for a pro. For an undermount, it can take 3–4 hours and may require removing the countertop. It’s not a huge job, but old plumbing can make it a headache.
How much does Home Depot charge for sink installation?
Home Depot’s install service typically runs $200–$400 for labor, but you must buy the sink from them. Their contractors are vetted, but you’re paying a markup on the sink itself.
Do you need a plumber to install a bathroom sink?
Not legally, in most places. But if you have old galvanized pipes, wonky shut-off valves, or a complex undermount sink, a plumber’s experience is worth the money.
