Cost to Replace a Bathroom Vanity: 2026 Price Guide

The cost to replace bathroom vanity units in 2026 lands almost anywhere between $400 and $3,800 for a typical job, and that enormous spread confuses homeowners more than any other bathroom number. The reason is simple: “replacing a vanity” can mean swapping a 24-inch builder-grade cabinet for a lookalike, or it can mean tearing out a single sink, moving plumbing, and installing a 60-inch double with a quartz top. Both are “just a vanity.” I’ll break the job into its real parts so you can price your specific situation instead of guessing.

Here’s where the money actually goes and how to keep the total in check.

The Quick Answer: Typical Total Cost

For a standard single-sink vanity replacement in 2026 — same size, same location, no plumbing moves — most homeowners pay $600 to $1,600 all in. A mid-grade 30 to 36-inch vanity with a cultured-marble or quartz top and professional installation sits right in the middle of that. Go bigger, add a second sink, or relocate the plumbing and you climb toward $2,500 to $3,800.

The two variables that swing the number hardest are the vanity’s size and top material, and whether plumbing has to move. Keep the footprint and the drain and supply lines where they are, and you stay on the low end. Change either and the price jumps.

Materials vs. Labor: The Split

On a typical job, materials make up the larger share and labor the rest. Here’s a realistic breakdown for a mid-grade 36-inch single vanity installed by a pro:

• Vanity cabinet: $200 to $900 depending on size and quality.
• Countertop: $100 to $700, from cultured marble to quartz or granite.
• New faucet: $60 to $300.
• Sink (if not integrated): $50 to $250.
• Plumbing parts — supply lines, P-trap, shutoffs: $30 to $80.
• Labor: $300 to $700 for a straightforward swap, more if tile or drywall repair is involved.

Labor typically runs $45 to $90 per hour for a handyman and $70 to $150 for a licensed plumber. A clean swap takes a pro two to four hours; anything involving old, corroded shutoffs or a tight, tiled-in cabinet takes longer and costs more.

Price by Vanity Size

Size drives both the cabinet cost and the countertop cost, so it’s the cleanest way to bracket your budget. Installed, ballpark 2026 totals look like this:

• 24-inch single: $400 to $900 — the classic small-bath or powder-room size.
• 30 to 36-inch single: $600 to $1,600 — the most common replacement.
• 48-inch single or small double: $1,000 to $2,200.
• 60 to 72-inch double: $1,600 to $3,800 — two sinks means two faucets, two drains, and a big top.

A double vanity isn’t just a wider cabinet — you’re paying for a second faucet, a second sink, a second drain assembly, and far more countertop, so it costs disproportionately more than a single of the same width.

The Big Cost Driver: Moving Plumbing

Nothing inflates a vanity budget faster than relocating the plumbing. If your new vanity puts the sink in a different spot — say you’re switching from a single to an offset double, or centering the bowl where the old one sat off to one side — a plumber has to move the drain and supply lines inside the wall or floor. That adds $300 to $1,000 or more, and if it means opening a finished wall, add drywall and paint repair on top.

The cheapest replacements keep the new sink directly over the existing drain rough-in. When you shop, measure where your current drain exits the wall and choose a vanity whose sink lines up with it. That single decision can save you a four-figure plumbing bill.

Countertop Choices and What They Cost

The top is where taste meets budget. From least to most expensive: a cultured-marble or acrylic integrated top runs $100 to $300 and includes the sink molded in, which also saves on a separate bowl. Laminate is cheap but rare on vanities now. Quartz and granite run $50 to $120 per square foot installed, so a 36-inch top lands around $250 to $500. Natural marble costs more and needs sealing.

For most bathrooms, a quartz top on a mid-grade cabinet is the sweet spot — it looks high-end, resists water and stains, and adds only a few hundred dollars over cultured marble. If you’re selling soon, quartz photographs well and reassures buyers; if it’s a rental or kid’s bath, an integrated cultured-marble top is the value play.

DIY vs. Hiring Out

A like-for-like vanity swap is one of the more DIY-friendly bathroom jobs, and doing it yourself removes the $300 to $700 labor line. If your shutoff valves work, the new sink lands over the old drain, and you’re comfortable with a P-trap and supply lines, a confident DIYer can finish in a weekend for the cost of materials alone.

Hire a pro when the shutoffs are frozen or leaking, when plumbing has to move, when the vanity is tiled into the wall or floor, or when you’re dealing with a stone top too heavy to set safely alone. A plumber also spots problems — a corroded supply line, an out-of-code trap — that a homeowner might reinstall by mistake. The labor buys both the work and the assurance it won’t leak behind the new cabinet.

Where to Save Without Regret

Smart savings on this project come from a few reliable moves. Keep the sink over the existing plumbing to dodge relocation costs. Choose a stock in-store vanity over a custom order, since custom cabinetry easily doubles the cabinet price. Reuse a faucet that’s only a few years old rather than buying new. And schedule the work as a standalone job rather than during a full remodel, where trades charge a premium for coordination.

Where not to cut: don’t reuse old, stiff shutoff valves, and don’t skip a proper P-trap or silicone seal at the wall. Those $30 details prevent slow leaks that rot the cabinet and floor — the exact damage that makes a $700 job turn into a $3,000 one next time.

Wall-Mount and Floating Vanities: A Special Case

Floating vanities look sleek and make a small bathroom feel bigger, but they carry a cost wrinkle worth knowing before you fall for the showroom photo. A wall-mount cabinet hangs entirely on the wall, so the studs need solid blocking to carry the load. If your wall does not already have a horizontal 2x brace behind the drywall at the right height, a contractor has to open the wall, add blocking, and patch it, which adds $150 to $500 in labor and drywall work. Floating vanities also usually pair with a wall-mounted faucet or an in-wall drain, both of which mean moving plumbing up inside the wall. Budget $300 to $900 more for a floating install than for an equivalent freestanding vanity that sits on the floor over the existing rough-in.

How Long the Job Takes

Timing helps you plan around a bathroom being out of service. A straightforward like-for-like swap is a half-day to full-day job: an hour or two to disconnect and remove the old unit, an hour to set and level the new cabinet, and another hour or two to connect the drain, supplies, faucet, and caulk. Add a day if the countertop is a separate stone piece being templated and fabricated, since that has to be measured, cut off-site, and returned. A job that involves moving plumbing or opening walls stretches to two or three days once you account for the plumber’s rough-in, an inspection if permitted, and drywall patching and paint.

Replace or Just Reface?

Before you buy a new vanity, decide whether you actually need one. If the cabinet box is solid and only the doors, top, or hardware look dated, refacing or repainting the existing cabinet plus a new top and faucet can renew the look for $200 to $600 instead of a full replacement. Replace the whole vanity when the cabinet is water-damaged, swollen, or moldy at the base, when you want a different size or layout, or when the sink or top is cracked. A swollen particleboard cabinet is a clear replace: once the base has wicked water and delaminated, no amount of paint saves it, and it will keep shedding into the bathroom.

Bottom Line on Vanity Replacement Cost

Budget $600 to $1,600 for a standard single-sink swap in 2026, and $1,600 to $3,800 for a large or double vanity or one that requires moving plumbing. The cost to replace bathroom vanity hinges on three levers you control: the size you pick, the countertop material, and whether the new sink can sit over the existing drain. Lock those in early, keep the plumbing where it is, and you’ll land at the low end of the range with a bathroom that looks completely renewed for a fraction of a full remodel.
