A bathroom vanity costs $300–$1,200 stock, $800–$3,000 semi-custom, or $2,500–$8,000+ fully custom for the cabinet itself — before countertop, sink, faucet, and installation. The tier you need depends almost entirely on one thing: whether your bathroom fits a standard width.
Those tier bands come from a 2026 contractor comparison of stock, semi-custom, and custom bathroom vanities. (Solid Kitchen & Bath) A cabinet wholesaler’s 2026 buyer’s guide lands in the same place: $200–$600 for RTA (ready-to-assemble) stock, $300–$1,200 big-box stock, $800–$2,500 semi-custom, $2,000–$8,000+ custom. (Buy Wholesale Cabinets) The numbers agree because the underlying economics are simple: standard sizes are cheap, choices cost money, and exactness costs the most.
Key takeaways
– Stock ($300–$1,200): fixed standard widths, available immediately, best for powder rooms and standard layouts.
– Semi-custom ($800–$3,000): more sizes, finishes, and storage options; 4–8 week lead time; the sweet spot for most primary baths.
– Custom ($2,500–$8,000+): built to your exact dimensions; worth it for odd alcoves and out-of-plumb walls, overkill for standard spaces.
– The countertop often costs as much as the cabinet — pair deliberately, not emotionally.
– Measure the alcove, door swing, and plumbing locations before shopping; a vanity two inches too wide is a very expensive mistake.
The Three Tiers, Honestly Compared
| Stock | Semi-custom | Custom | |
|---|---|---|---|
| Cabinet cost | $300–$1,200 | $800–$3,000 | $2,500–$8,000+ |
| Lead time | Often immediate | 4–8 weeks | Weeks to months |
| Widths | Fixed: 24/30/36/48/60″ | More options | Your exact dimensions |
| Construction | Often particleboard | Plywood common | Solid wood, joinery |
| Best for | Powder rooms, rentals, standard baths | Most primary bath remodels | Odd alcoves, luxury builds |
Tier pricing reflects quality, size, and customization as the three big drivers — small pre-made units start at a few hundred dollars while large, high-quality, customized units climb from there. (Litchfield Builders)
Stock Vanities: $300–$1,200
Stock vanities are factory-built in standard widths — usually 24, 30, 36, 48, and 60 inches — and sold as-is. Big-box stock typically runs $300–$1,200, while RTA (flat-pack, assemble-it-yourself) stock can dip to $200–$600. (Buy Wholesale Cabinets)
What you get: a functional cabinet, often particleboard box construction with a veneer or thermofoil finish, soft-close hardware on better models, and a vanity top sometimes bundled in. For a hall bath, powder room, or rental, this is genuinely all you need.
The honest limitations: fixed widths mean filler strips or visible gaps in non-standard alcoves. Particleboard and high humidity are old enemies — in a steamy bathroom with poor ventilation, budget boxes swell and peel years before plywood ones. And the finishes, while fine, won’t fool anyone up close.
When stock wins: the alcove fits a standard width cleanly, the bathroom isn’t your forever-home showpiece, or the budget needs the money more in the shower. A $500 stock vanity paired with a nice countertop and faucet reads far more expensive than it is — because hands and eyes interact with the top, not the box.
Semi-Custom: $800–$3,000
Semi-custom vanities start from standard cabinet lines but offer real choices: more widths and depths, finish and door-style options, interior storage configurations (drawers vs. doors, pull-outs, dividers), and sometimes modified dimensions. Expect $800–$3,000 for the cabinet and a 4–8 week lead time. (Solid Kitchen & Bath)
What you get: the price-to-quality sweet spot for most primary bathroom remodels. Plywood box construction is common, finishes are more durable, and you can solve the storage problems that actually matter — deep drawers for a hair dryer, a pull-out for cleaning supplies, dividers that end the junk drawer.
The honest limitations: “semi” still means constraints. Truly odd dimensions, angled walls, or matching an existing built-in exactly will push you to full custom. And 4–8 weeks means ordering during pre-construction, not after demolition — a late vanity order is one of the classic schedule-killers.
When semi-custom wins: it’s your primary bathroom, you’ll use it daily for years, and you want storage that fits your actual stuff. The jump from stock to semi-custom buys more daily-life improvement per dollar than almost any other upgrade in the bathroom.
Custom: $2,500–$8,000+
A custom vanity is built to your exact dimensions by a cabinetmaker or specialty shop — any width, any depth, any configuration, solid-wood face frames, real joinery. Budget $2,500–$8,000 or more for the cabinetry alone. (Solid Kitchen & Bath)
What you get: a perfect fit in imperfect spaces. Older homes are full of vanity alcoves that are a few inches off standard — mid-century and 1980s houses especially — where stock leaves an awkward gap and semi-custom can’t quite close it. Custom also solves out-of-plumb walls, integrates with existing millwork, and delivers furniture-grade construction that outlasts the house’s next two remodels.
The honest limitations: price, obviously, and time — weeks to months from order to delivery. Custom is also the easiest place in a bathroom to overspend emotionally: a $6,000 vanity in a $12,000 bathroom is a budgeting error, not a luxury.
When custom wins: the space genuinely doesn’t fit standard sizes, you’re building a forever-home primary suite, or the vanity needs to match existing built-ins. If a standard width fits, custom is paying triple for the privilege of the same rectangle.
Countertop Pairings That Make or Break the Budget
Here’s the part first-time remodelers miss: the countertop frequently costs as much as the cabinet. Angi bundles “countertops/vanity” at $400–$4,300 as a single line item — the range is that wide because the top drives it. (Angi)
Sensible pairings by tier:
- Stock cabinet ($300–$800) → cultured marble or laminate top ($100–$400). The whole vanity lands under $1,200 and looks clean and intentional.
- Semi-custom cabinet ($1,200–$2,500) → quartz or granite remnant ($400–$1,200). Bathroom tops are small — ask fabricators about remnants from kitchen jobs, which can cut stone costs dramatically.
- Custom cabinet ($3,000+) → quartz, quartzite, or marble slab ($800–$2,500+). At this tier the top should match the cabinet’s lifespan.
One caution: natural stone in a bathroom needs sealing and maintenance that quartz doesn’t. If “wipe and forget” is your lifestyle, engineered quartz earns its premium. And whatever you choose, confirm the sink type before the top is fabricated — undermount, drop-in, and vessel sinks each need different cutouts, and a wrong cutout is a ruined slab.
Installation: What It Costs and What It Includes
A straightforward like-for-like vanity swap — old one out, new one in, same plumbing locations — is a half-day job, typically a few hundred dollars in labor. A full replacement with plumbing adjustments runs higher, and moving the drain or supply lines adds $450–$1,800 before cabinetry work even begins, per contractor cost analyses.
What the install quote should include: removal and disposal of the old vanity, setting and leveling the new cabinet, countertop setting, sink and faucet hookup, and reconnecting supply and drain lines. What it often doesn’t include: backsplash repair where the old vanity’s taller backsplash was, paint touch-up, or flooring patches if the new vanity’s footprint is smaller. Ask. A vanity swap that reveals a flooring gap is a $500 surprise nobody budgeted.
Floating vanities deserve a special note: the cabinet costs roughly the same as floor-mount, but the wall needs reinforced blocking to carry the load — cheap if the walls are open during a gut, expensive as a retrofit into finished walls.
Three Vanity Scenarios, Priced
The rental refresh — ~$650 all-in. Off-the-shelf 30-inch stock vanity with integrated top ($350), basic chrome faucet ($60), DIY install over a weekend, $100 in paint and caulk. Looks clean, rents fast, owes nobody anything.
The primary bath upgrade — ~$2,800 all-in. 48-inch semi-custom vanity in a painted finish ($1,600), quartz remnant top with undermount sink ($700), mid-range widespread faucet ($180), professional install with new supply lines ($300+). Ordered 6 weeks before demolition. This is the value sweet spot — daily-use quality without the custom price.
The forever-home statement — ~$7,500 all-in. Custom 60-inch double vanity in white oak ($4,500), quartzite slab top ($1,800), two wall-mount faucets ($600), pro install with minor drain adjustment ($600+). Built to the tenth of an inch for an alcove that’s 58.5 inches wide — the exact situation where custom earns its keep.
Questions to Ask Before You Buy
- Does the price include the top, sink, and faucet — or just the cabinet? “Vanity” means different things to different sellers. Get the complete list.
- What’s the box made of? Plywood boxes handle bathroom humidity far better than particleboard. In a steamy primary bath, this matters more than the door style.
- What’s the lead time, in writing? “About a month” from a sales rep is not a delivery date. Your contractor’s schedule depends on the real one.
- What are the exact dimensions — and have I measured twice? Width, depth, height, plus door-swing clearance and distance to the toilet (15 inches from centerline to any side wall is the common code minimum). A vanity two inches too wide is a return-shipping nightmare.
- Who handles the plumbing disconnect and reconnect? If you’re DIYing the swap, know where your water shutoffs are and have a bucket ready. Supply-line connections are the most common DIY leak source.
- If the new vanity is smaller, who patches the floor and wall? Decide before the old one comes out, not after.

Frequently Asked Questions
How much does it cost to replace a bathroom vanity?
For a like-for-like replacement with a stock vanity, expect $500–$1,500 all-in including basic installation. A semi-custom vanity with a stone top and professional install typically lands at $1,800–$3,500. Moving plumbing locations adds hundreds to low thousands on top.
Is a custom bathroom vanity worth it?
Only when the space demands it — odd alcove widths, out-of-plumb walls, or matching existing built-ins. If a standard 24/30/36/48/60-inch width fits your space, a semi-custom vanity delivers 90% of the result for a third of the price.
What’s the most popular bathroom vanity size?
For small to mid-size bathrooms, 30–36 inches single-sink is the workhorse; 48 inches suits standard full baths; 60–72 inches with double sinks is the primary-suite standard. Measure your wall, door swing, and toilet clearance before falling in love with a size.
Can I install a bathroom vanity myself?
A like-for-like swap is a realistic DIY project if you’re comfortable with water supply shutoffs and drain connections — but supply-line leaks are the classic DIY failure, so keep the water off until every connection is tested, and know when to call a plumber. Our small bathroom cost guide covers where DIY savings are real and where they aren’t.
How long does a custom vanity take to arrive?
Typically several weeks to a few months from order to delivery, depending on the shop’s backlog and finish complexity. Order it during the planning phase — a vanity that arrives after the plumber has left is a scheduling disaster.
