Based on aggregated data, bathroom vanity installation costs $500 to $3,000, with a typical project landing near $1,500. Materials — the cabinet, countertop, sink, and faucet — account for roughly $200 to $1,500 of that total, and labor for $250 to $1,300. Most jobs take 4 to 8 hours and no permit is typically required.
That $2,500 spread is not really about the vanity. It is about two questions: how wide the cabinet is, and whether the plumbing has to move. A 30-inch prefab dropped onto existing stub-outs and connected to the same drain is a half-day job near the bottom of the range. A 72-inch double that needs a second drain teed into the waste stack, a stone top templated to fit, and drywall opened and patched afterward is a different project that happens to share a name.
Bathroom Vanity Installation Cost at a Glance
| Component | Low | Typical | High |
|---|---|---|---|
| Materials (cabinet, top, sink, faucet) | $200 | $700 | $1,500 |
| Labor (removal, set, plumbing connections) | $250 | $700 | $1,300 |
| Disposal, supplies, and fasteners | $50 | $100 | $200 |
| Total installed | $500 | $1,500 | $3,000 |
Labor and materials land at roughly the same share of a typical job — near $700 each on a $1,500 project. That balance is unusual for a bathroom trade. On tile work or a shower rebuild, labor dominates; on a vanity, the cabinet you pick can double the bill on its own, which is why two quotes for “installing a vanity” can differ by $1,500 without either contractor charging a different hourly rate.
Cost by Vanity Width
Width is the first number a quote keys off, because it sets the cabinet price, the countertop square footage, and whether the job needs one sink or two.
| Vanity Width | Cabinet + Top | Installed Total | Notes |
|---|---|---|---|
| 24-inch single | $200–$450 | $500–$900 | Powder rooms and tight secondary baths |
| 30-inch single | $250–$600 | $550–$1,100 | The most common replacement size |
| 36-inch single | $300–$750 | $650–$1,350 | Standard primary-bath single |
| 48-inch single | $450–$1,000 | $850–$1,800 | Single sink with usable counter run |
| 60-inch single | $550–$1,200 | $1,000–$2,200 | Off-center bowl, long counter |
| 60- to 72-inch double | $700–$1,500 | $1,300–$3,000 | Two bowls, two faucets, two drains |
Price per inch of width is not linear. Going from 24 to 36 inches adds cabinet material and a bit more countertop, and the labor is essentially unchanged — the same single drain, the same two supply connections. Going from a 60-inch single to a 60-inch double adds a whole second plumbing set: a second sink, a second faucet, a second P-trap, and a second drain that has to be teed into the existing waste line. That is why the double row is the only one in the table that reaches the top of the $3,000 aggregated range.
Anything above 72 inches, or any width that is not a standard 24/30/36/48/60/72 increment, usually means a custom cabinet. Custom fabrication carries a lead time of several weeks and prices at the top of the materials range and beyond.
Does the Plumbing Move? The Fork That Sets the Price
This is the single biggest cost decision on a vanity job, and it is usually made — accidentally — when someone picks a cabinet whose bowl does not line up with the existing rough-in.
| Scenario | Labor | Typical Installed Total | What Happens |
|---|---|---|---|
| Same footprint, existing stub-outs reused | $250–$500 | $500–$1,300 | Shut off, disconnect, set cabinet, reconnect supplies and P-trap |
| Sink shifts within the same cabinet | $400–$700 | $900–$1,700 | New flexible supply lines, re-aligned or extended P-trap |
| Supply and drain relocated to a new wall position | $700–$1,300 | $1,700–$3,000 | Drywall opened, lines re-run, stub-outs reset, wall patched |
The reason the third row costs two to three times the first is that it stops being carpentry and becomes plumbing. Supply lines can often be extended with a short run of PEX or copper behind the wall. The drain is the constraint: a lavatory drain needs slope to reach the trap arm and a vent within code distance, so moving it more than a foot or so laterally frequently means opening the wall cavity and re-plumbing back to the stack.
Two practical markers separate the cheap job from the expensive one. First, a standard vanity rough-in puts the drain roughly 18 to 22 inches above the finished floor and centered on the cabinet — a replacement whose bowl sits in the same place connects to what is already there. Second, a floating (wall-mounted) vanity almost always changes the geometry: the drain has to sit higher, above the cabinet’s underside, so it is hidden. Converting from a freestanding vanity to a floating one typically means relocating the drain even when the vanity stays in the same spot, which is why floating units land in the upper half of the range regardless of width. A floating vanity also needs blocking inside the wall to carry the load, adding $100 to $300 in labor and drywall work when none exists.
Related plumbing work is often bundled in at the same visit while the lines are open — see bathroom plumbing rough-in for what moving supply and waste lines costs as a standalone scope.
Cost by Vanity Type
| Type | Cabinet + Top | Installed Total | Cost Driver |
|---|---|---|---|
| Freestanding prefab (in stock) | $200–$700 | $500–$1,300 | Cheapest path; sits on the floor, hides the trap |
| Freestanding, semi-custom finish | $500–$1,100 | $900–$2,000 | Solid-wood door fronts, soft-close, stone top |
| Corner vanity | $300–$800 | $700–$1,500 | Fits an odd footprint; may need supply-line re-angling |
| Floating / wall-mounted | $450–$1,200 | $1,100–$2,400 | Wall blocking plus drain relocation |
| Vessel-sink vanity | $400–$1,100 | $1,000–$2,200 | Taller faucet, drain height changes, no cutout in the top |
| Double-bowl | $700–$1,500 | $1,300–$3,000 | Two of every plumbing component |
| Custom-built | $1,200–$1,500+ | $2,200–$3,000+ | Shop fabrication, templated top, weeks of lead time |
A vessel sink looks like a low-cost swap — the bowl sits on top, so the countertop needs only a drain hole rather than a full undermount cutout. In practice it changes three things at once: the faucet has to be a tall vessel model or a wall-mount, the drain tailpiece sits higher, and the cabinet is often ordered shorter (30 to 32 inches instead of the 34 to 36 inches of a standard comfort-height vanity) so the finished bowl rim lands at a usable height. Each of those is a small charge; together they explain the $1,000-plus floor on the installed figure.
The Vanity Top
The top is quoted as its own line on most vanity jobs, and it is also the part most often replaced without the cabinet. Stock tops with the bowl already molded in or mounted below run about $120 to $880 for a 37-inch cabinet, from cultured marble at the bottom to quartz at the top, while a stone top cut to measure is billed by the square foot at $40 to $120 plus $75 to $150 for every undermount sink opening. Kept on its existing cabinet, a new top costs $300 to $1,800 installed; pricing by material, width and cutout is compiled in bathroom countertop replacement cost.
A prefab vanity sold as a complete unit with a cultured-marble or laminate top is the reason the low end of the range exists at all. Buying the cabinet and the top separately, in stone, is how a 36-inch vanity moves from a $650 job to a $1,350 one without changing a single dimension.
Sink and Faucet Cost
| Item | Typical Cost | Notes |
|---|---|---|
| Drop-in sink | $40–$150 | Rim rests on the top; simplest cutout |
| Undermount sink | $70–$300 | Requires a stone or solid-surface top and edge polishing |
| Vessel sink | $100–$500 | Sits on top; needs a matching tall faucet |
| Integral sink (cultured marble / solid surface) | Included in top | No separate sink or cutout charge |
| Standard faucet | $50–$250 | Centerset or single-hole |
| Widespread or wall-mount faucet | $200–$900 | Wall-mount requires valve work inside the wall |
| Pop-up drain assembly and P-trap kit | $20–$60 | Replaced on most jobs rather than reused |
| Supply lines (pair) | $10–$30 | Braided stainless; commonly replaced with the vanity |
Sink and faucet are commonly quoted as owner-supplied, which is why the same contractor’s bid can look $400 cheaper than another’s for identical work. On a bid comparison, the line that matters is whether the fixture is inside the number or outside it.
A wall-mount faucet is a quiet cost multiplier: the valve body sits inside the wall, so the wall opens, and the finished height has to be set against the eventual bowl rim before the drywall closes. Detailed sink-side pricing, including pedestal and drop-in swaps without a cabinet, is covered in bathroom sink installation cost. A faucet changed on its own, with the cabinet and top left in place, is a far smaller purchase — $150 to $680, roughly two thirds of it labor — priced in bathroom faucet replacement cost.
Removal, Disposal, and Wall Repair
The old vanity has to come out before the new one goes in, and what is behind it is the most common source of a mid-job change order.
| Task | Typical Cost |
|---|---|
| Disconnect, demo, and haul away old vanity | $100–$300 |
| Drywall patch and paint behind the old cabinet | $100–$350 |
| Larger drywall repair (opened wall, relocated lines) | $150–$400 |
| Backsplash removal and re-tile | $100–$400 |
| Flooring patch where the old cabinet footprint was larger | $150–$500 |
| Shut-off valve replacement (pair) | $50–$200 |
| Subfloor repair under a leaking old vanity | $300–$1,000+ |
Two of these are near-certain rather than optional. Wall and flooring almost never run underneath an old vanity — tile and paint typically stop at the cabinet’s edge — so a narrower replacement exposes bare, unfinished floor and wall. Matching a discontinued tile is frequently impossible, which is the practical reason so many vanity replacements are specified at the same width as the old unit or wider.
The mirror above the vanity is the third near-certainty, and it is priced separately because its removal is a different kind of work. Where the existing mirror is bonded to the drywall with mastic rather than held on clips, taking it down pulls the paper face off the board and adds the same $100 to $350 patch-and-paint line that appears in the table above — on a wall that was not otherwise in scope. Bathroom mirror installation runs $75 to $950 with a typical job near $250, and roughly 60 percent of that is the mirror rather than the labor, which is the reverse of the split on the cabinet below it.
Old shut-off valves are the other one. A multi-turn valve that has not moved in fifteen years often will not reseal after it is closed, and replacing the pair with quarter-turn valves runs $50 to $200 rather than discovering the drip after the new cabinet is set. Where the old vanity has been leaking, the damage is under the cabinet floor and the subfloor beneath it — subfloor replacement and water damaged floor repair price that scope, and it is the most common reason a $900 vanity swap becomes a $2,500 one.
Materials vs Labor: Where the Money Goes
| Component | Low | Typical | High | Share of Typical Job |
|---|---|---|---|---|
| Materials | $200 | $700 | $1,500 | ~47% |
| Labor | $250 | $700 | $1,300 | ~47% |
| Disposal and supplies | $50 | $100 | $200 | ~6% |
| Total | $500 | $1,500 | $3,000 | 100% |
At an aggregated bathroom-trade rate near $115 per hour and a typical duration of 4 to 8 hours, the $250 to $1,300 labor band tracks the clock closely. A straight swap is a single technician for half a day. The high end is either two trades — a plumber for the lines, a carpenter or handyman for the cabinet and top — or a single job that spans two visits because the wall was opened and has to be patched, primed, and painted after the plumbing inspection point.
Hourly rates split by who does the work. A handyman or installer typically bills less per hour than a licensed plumber, and a like-for-like swap does not require a plumbing license in most jurisdictions. Once supply or waste lines are cut into and re-run, it usually does — and that reclassification of the same task is a real part of why the plumbing fork above is so steep.
DIY vs Professional Installation
A vanity is one of the more commonly self-performed bathroom projects, for a specific reason: when the plumbing stays put, the job is disconnect, lift, set, level, shim, reconnect. There is no tile to keep flat, no waterproofing to fail, and nothing behind a wall that a mistake can reach.
The materials side of a DIY job, for a 36-inch single vanity:
| Item | Typical Cost |
|---|---|
| Prefab vanity with top and integral or drop-in sink | $200–$750 |
| Faucet | $50–$250 |
| P-trap and pop-up drain assembly | $20–$60 |
| Braided supply lines (pair) | $10–$30 |
| Quarter-turn shut-off valves (pair, if replaced) | $20–$50 |
| Silicone, plumber’s putty, shims, screws | $20–$40 |
| Drywall patch compound, primer, paint | $30–$80 |
| Basin wrench, level, stud finder (if not owned) | $40–$120 |
| Disposal fee or dump run for the old cabinet | $25–$75 |
| DIY total | $415–$1,455 |
Against $650 to $1,350 for a professionally installed 36-inch vanity, the DIY saving on a same-footprint swap is real but narrow at the low end — roughly $250 to $700, which is the labor line. It widens sharply on a large or double vanity, where the labor figure climbs but the cabinet price is identical whoever buys it.
What the figures do not capture is where self-installed jobs stall. The three recurring ones: a stone top that cannot be cut on site without a wet saw and a diamond blade; a drain that turns out to be a foot off from the new bowl, converting the job into wall work; and a floor that is out of level enough that the cabinet has to be shimmed and scribed before the top will sit flat. A cast-stone or quartz top on a 60-inch vanity also weighs enough to need two people to lift — a practical constraint rather than a skill one.
Cost by City
Cabinets, tops, faucets, and sinks are priced nationally — the same 36-inch prefab is the same price in Houston as in Chicago. The labor half of the job, roughly $250 to $1,300, is what moves. Applying the formula City Adjusted Cost = National Average × City Labor Adjustment Factor to the $1,500 national typical project:
| City | Labor Adjustment Factor | Adjusted Typical Total | Adjusted Labor Portion | vs. National |
|---|---|---|---|---|
| Chicago, IL | 1.33 | $1,995 | $930 | +33% |
| New York, NY | 1.23 | $1,845 | $860 | +23% |
| Seattle, WA | 1.29 | $1,935 | $905 | +29% |
| Houston, TX | 0.93 | $1,395 | $650 | −7% |
| San Antonio, TX | 0.85 | $1,275 | $595 | −15% |
Labor adjustment factors are derived from BLS Occupational Employment and Wage Statistics (May 2025): the median ratio of local to national hourly wages across the trades that do this work. How this is calculated.
Chicago carries the highest factor in the dataset at 1.33, ahead of New York at 1.23 — trade labor tracks union density and local contractor supply rather than the general cost of living, which is why the ordering runs against intuition. San Antonio sits at the bottom at 0.85. Because materials do not move with the factor, the real spread on a vanity job is smaller in percentage terms than on a labor-heavy project like tile work: on a $1,500 typical job, only the $700 labor slice is exposed to the local rate. The cost calculator applies any city’s factor to a specific vanity size and scope.
Related Bathroom Costs
A vanity is rarely replaced on its own. When it is part of a wider project, the sequence matters more than the individual prices — flooring generally goes in before the cabinet is set, so the cabinet is not sitting on a seam.
- Bathroom sink installation — replacing the bowl and faucet while keeping the existing cabinet, at $280 to $1,400.
- Toilet installation — the other fixture commonly swapped in the same visit, since the water is already off.
- Half bath remodel — $1,500 to $12,000, where a vanity swap is usually the anchor line item.
- Small bathroom remodel — $3,000 to $15,000, at which point the vanity is one of six or seven scopes.
- Bathroom tile installation — floor tile that runs under the cabinet footprint has to go down first.
- Bathroom plumbing rough-in — what it costs when the supply and waste lines have to move.
- Tile installation and porcelain tile — pricing for the floor the vanity sits on.
The full range of bathroom scopes and their national figures sits on the bathroom remodeling cost hub.
Lifespan and Cost per Year
A prefab vanity cabinet in a well-ventilated bathroom typically lasts 10 to 15 years before the finish fails at the base or the doors sag; a solid-wood or semi-custom cabinet commonly runs 20 years or more. On the aggregated figures, a $1,500 typical installation over a 15-year service life works out to roughly $100 per year. A $500 builder-grade swap that is replaced in 8 years lands near $63 per year — cheaper, but not by the margin the sticker price implies, because the $250 to $1,300 labor line is paid again on every replacement.
Moisture is what ends most vanities early. Particleboard and MDF carcasses swell where a supply line drips or where a bowl overflows, and the failure is at the cabinet base where it is invisible until the toe kick softens. That is the mechanism behind the subfloor repair line above, and it is the argument for the plywood-carcass upgrade that typically adds $100 to $300 to the cabinet price.
How to Reduce Bathroom Vanity Installation Cost
- Keep the new vanity in the existing footprint. Reusing the stub-outs and drain holds labor near $250 to $500 instead of $700 to $1,300.
- Match or exceed the old vanity’s width so the unfinished floor and wall behind it stay covered — a narrower cabinet turns into a $150 to $500 flooring patch.
- Ask whether the quote includes the faucet, the sink, and the P-trap kit, or whether those are owner-supplied. That single question accounts for $80 to $700 of difference between otherwise identical bids.
- Price a stone top from a remnant. A vanity top is small enough to come out of a slab offcut, which is where granite and quartz undercut their per-square-foot kitchen pricing.
- Combine the vanity with any other fixture swap in the same visit — the shut-off, drain-down, and trip charge are paid once.
- Compare a prefab unit with an integral cultured-marble top against a separate cabinet plus stone top: a molded-in bowl has no opening to cut, where a fabricator bills $75 to $150 for each undermount cutout.
- Replace the shut-off valves at the same time. A $50 to $200 valve pair swapped while the cabinet is out costs a fraction of what it costs after a new top is set.
