Cost to Replace a Bathroom Vanity

It costs $500 to $2,800 to replace a bathroom vanity, installed. A stock 30-inch vanity with a cultured-marble top, swapped in the same spot, is $500 to $1,200. A wider double-sink unit with a stone top and a new faucet runs $1,500 to $2,800.

The vanity cabinet and top are $200 to $1,500 of that. The rest is the plumber's time, the faucet, the drain assembly, and patching the wall and floor where the old unit sat.

What It Costs to Replace a Bathroom Vanity

A like-for-like swap of a stock 24 to 30-inch vanity is $500 to $1,200. A 36 to 48-inch stock unit with a stone top is $900 to $1,800. A 60-inch or wider double-sink vanity is $1,600 to $3,200.

A like-for-like swap is a half-day job. Anything that moves the drain or the supply lines, or that repairs the floor underneath, is a one to two-day job.

The table below shows cost by size. The next section covers where the money actually goes.

Where the Money Goes

The cabinet is $100 to $900 for stock, more for semi-custom. The top with an integrated or undermount sink is $100 to $700.

Labor is $200 to $600 for a straightforward swap: disconnect, remove, set the new cabinet level, install the top and sink, and reconnect the supply lines and drain.

A new faucet is $80 to $400, and new shutoff valves and supply lines add $40 to $150. See our Kitchen and Bath cost guides for the wider project.

Vanity Sizes and Types

A 24 to 30-inch single vanity fits a small bathroom. A 36 to 48-inch single gives more counter and storage. A 60 to 72-inch double-sink vanity suits a primary bath.

Freestanding vanities sit on the floor and are the standard. Floating, or wall-mounted, vanities look lighter and make the floor easier to clean, but they need solid blocking in the wall and cost more to install.

Stock cabinets come in fixed sizes and finishes. Semi-custom lets you pick the width, the door style, and the drawer layout for 50 to 150 percent more.

Countertop Options for a Vanity

Cultured marble, a molded top with an integrated sink, is the budget choice at $100 to $300 and needs no separate sink install.

Quartz and granite tops with an undermount sink are $200 to $700 for a vanity-sized piece and are the popular midrange.

Solid surface, a wood top sealed for bath use, or a vessel sink on a flat counter are all options that change the look and the price.

Like-for-Like vs. Moving the Plumbing

The cheap version keeps the drain and the supply lines exactly where they are and buys a vanity sized to match. The plumber just reconnects.

Changing the width or switching to a floating vanity often means moving the drain up or over inside the wall, at $150 to $600, plus opening and patching the wall.

A double sink where there was one adds a second drain and a second set of supply lines, at $300 to $900.

What Drives the Price Up

An out-of-square wall or an unlevel floor means shimming and scribing the new cabinet, which adds time. Old tile that ends exactly at the vanity edge leaves a gap or a bare patch to deal with.

Rotten flooring or a soft subfloor under the old vanity, common from years of small leaks, has to be repaired first.

Corroded shutoff valves that will not close, or galvanized supply lines, turn a simple reconnect into a small plumbing repair.

What Comes With a Vanity Swap

Plan to replace the faucet, the pop-up drain, the P-trap, and the supply lines at the same time. They are cheap, and matching new parts to an old vanity is a false economy.

It is also the moment to add or move a GFCI outlet, upgrade the light or mirror, and repaint, since the wall behind the old vanity is usually unpainted.

If the floor tile stops at the old footprint, a smaller new vanity leaves bare subfloor. Measure before you buy.

DIY vs. Hiring a Plumber

A like-for-like vanity swap is a reasonable weekend DIY if you are comfortable under a sink: shut the valves, disconnect, remove, set level, and reconnect.

Hire a plumber if the shutoffs are seized, the lines are galvanized, you are moving the drain, or you find water damage. Those are where a DIY swap goes sideways.

Even on a DIY job, budget for new valves, a new faucet, and a tube of caulk. The parts add up to $150 to $400.

Timeline

A same-spot swap is 3 to 6 hours, most of it removing the old unit and leveling the new one.

A swap that moves plumbing or repairs the floor is a one to two-day job with a wall-patch and paint step and sometimes an inspection.

Order the vanity and confirm it is undamaged before you demo the old one, so you are not left with no sink.

Choosing a Vanity That Lasts

Look for a plywood box rather than particleboard, especially the floor of the cabinet under the sink, which is the first thing to swell if a supply line ever weeps.

Soft-close doors and drawers, dovetailed drawer boxes, and a finish rated for a humid room all signal a cabinet that will hold up.

A separate top and undermount sink is easier to replace later than a molded one-piece unit if the sink ever cracks or stains.

Matching the Vanity to the Bathroom

In a small bathroom, a vanity with drawers on one side and a door on the other holds more than an all-door cabinet, and a shallow 18-inch-deep unit opens up a tight floor.

A wall-hung vanity makes a small room feel larger and is easier to mop under, but it needs blocking in the wall and puts the plumbing on display, so buy a clean-looking trap.

Match the height to who uses it. Standard is 32 inches to the top; a 36-inch comfort height suits adults, while a lower unit is better for a kids' bathroom.

Regional and Home-Age Differences

Plumber labor tracks the local rate, so the reconnect portion of the job can be $150 in one market and $500 in another for the same work.

Older bathrooms add cost. Galvanized supply lines, a drum trap, or a drain that is off-center from any modern vanity all turn a simple swap into a small plumbing project.

Homes with tile that runs wall to wall behind the old vanity are the other common surprise, since a different-sized new unit leaves an unfinished strip to patch.

How to Keep the Cost Down

First, keep the plumbing where it is and buy a vanity sized to the existing drain location.

Second, choose a stock cabinet in a standard width. Third, do the removal and the repaint yourself. Fourth, use a cultured-marble top if the look works for you; it is the cheapest and needs no sink install.

Fifth, if a plumber is coming anyway for other work, add the vanity to that visit.

Bottom Line

Budget $500 to $1,200 to replace a bathroom vanity like-for-like with a stock unit, and $1,500 to $2,800 for a wider or double-sink vanity with a stone top and new faucet. Moving the plumbing adds $150 to $900.

Keep the drain where it is, replace the faucet and valves while you are in there, and check the subfloor for old leak damage. For the bigger picture, see our bathroom remodel, shower tile, and countertop guides. Low-flow faucets from the EPA WaterSense list cut water use with no drop in feel.
