Bathroom Vanity Installation Cost in 2026: Labor, Plumbing and Tops

Replacing a vanity is the closest thing to a cheat code in bathroom renovation: it changes the whole room, it takes one day, and it rarely needs a permit. The trap is that the sticker price of the vanity is often the smaller half of the bill. In 2026, installation labor alone runs $350 to $1,600, and installed totals land between $700 and $4,500.

Bathroom Vanity Installation Cost in 2026

• Labor only, direct swap, same plumbing: $350-$700
• Labor with new faucet, drain and supply lines: $500-$950
• Labor with plumbing relocation: $900-$1,600
• Stock 24-36 inch vanity installed: $700-$1,700
• Semi-custom 48-60 inch vanity installed: $1,800-$3,200
• Double-sink or custom vanity installed: $2,800-$4,500+

What Drives the Labor Number

Plumbers and finish carpenters price a vanity job by how much has to change behind the wall. A same-footprint swap with existing valves is two to four hours. Once the supply lines move, the drain gets re-cut or the wall needs patching and paint, the job becomes a full day and often two trades.

• Removing and hauling the old vanity: $75-$200
• New shutoff valves and supply lines: $120-$250
• P-trap and drain reconfiguration: $150-$400
• Faucet installation: $120-$250
• Wall patch, backsplash and paint touch-up: $150-$450
• Floor tile patch where the old cabinet sat: $200-$600

If the new vanity is a different width than the old one, budget for floor and wall repair. That is the line item most quotes leave out.

Vanity Top Costs

• Cultured marble integrated top: $180-$400
• Laminate: $120-$300
• Granite: $350-$900
• Quartz: $450-$1,300
• Marble: $600-$1,800
• Solid surface: $400-$1,000

Floating vs Freestanding Vanities

Wall-mounted floating vanities cost $150-$450 more to install because the wall needs blocking between studs and the drain usually has to move up. They are worth it in small bathrooms — the visible floor makes the room read larger — but do not treat the install as a like-for-like swap.

DIY vs Hiring a Pro

A same-size swap with accessible shutoffs is a legitimate weekend DIY and saves $400-$700. Call a plumber the moment you find corroded valves, a cast-iron drain, tile that ends behind the old cabinet, or a stone top over 40 pounds per foot that needs two people and dead-flat shimming.

Frequently Asked Questions

How much does it cost to install a bathroom vanity in 2026?

Labor is $350-$1,600 depending on plumbing work. Installed totals including the vanity and top run $700-$1,700 for stock units and $2,800-$4,500 for double or custom vanities.

How much does a plumber charge to install a vanity?

Most plumbers charge $95-$165 per hour with a two-hour minimum, so a straightforward swap is $250-$500 and a job with new valves, drain work and a faucet is $600-$950.

Is it cheaper to buy a vanity with the top included?

Usually yes. A pre-assembled vanity with an integrated cultured marble or engineered stone top saves $200-$500 versus buying a cabinet and a fabricated top separately, and it removes a template-and-return trip.

How long does vanity installation take?

Two to four hours for a direct replacement, a full day if plumbing moves or the wall and floor need patching, and two days when a stone top has to be templated and returned.

Do I need a permit to replace a bathroom vanity?

Not for a like-for-like swap in most US jurisdictions. A permit is typically required once you relocate supply or drain lines inside the wall or add a second sink.
