Cost to Replace a Bathroom Vanity: 2026 Guide

The short answer: replacing a bathroom vanity typically costs $700–$4,500 all-in — the cabinet itself, the plumber and installer, plus the top, sink, and faucet. The vanity unit runs $300–$3,800 depending on size and construction (HomeAdvisor, Jun-2026), basic professional installation runs $576–$871 per vanity (Homewyse, May-2026), and full vanity projects ranging from simple swaps to stone-top doubles land between $300 and $4,000 at a national average near $1,600. Every figure below is a third-party US range, not our pricing — use them to read quotes line by line.

What does replacing a bathroom vanity include?

A vanity replacement is a small project with four separate budget lines, and quotes get confusing exactly because contractors bundle them differently. First comes the cabinet box — the vanity itself, sized like a narrowed kitchen base at 34½ inches high and 21 inches deep (see our vanity sizes guide for the 24 to 60-inch width grid). Second is removal and disposal of the old unit. Third is installation plus plumbing: setting and leveling the new box, then reconnecting the drain, supply lines, and faucet. Fourth is the top, sink, and faucet — included with some vanities, billed separately with others. When two quotes disagree by a thousand dollars, they almost always disagree on which of these four lines are inside the number.

How much does the vanity itself cost?

The box is usually the biggest single line. HomeAdvisor's Jun-2026 bathroom data puts vanity units at $300–$3,800, with size, construction, and whether the sink and faucet are bundled deciding where you land:

• Stock singles (24–36 inches): roughly $300–$1,200 for the cabinet. A 30-inch Shaker vanity cabinet is the volume sweet spot — standard plumbing cutouts, standard tops, no custom surcharges. Powder rooms can drop to a 24-inch vanity and save on both box and top.
• Doubles (48–60 inches): roughly $800–$3,800. A 60-inch double vanity cabinet costs more as a box, but per-sink it often beats two singles — one cabinet, one top, one install visit. Tight 48-inch doubles save on the box and spend it back on trickier plumbing.
• Top-included vs box-only: bundled cultured-marble or quartz tops look pricier until you price a separate stone top — always compare the cabinet-plus-top total, not the cabinet alone. Box-only units leave you free to pick the stone but add templating and a second trade.
• Construction tiers: particleboard anchors the low end; all-plywood with soft-close hardware sits mid-range and resists bathroom humidity far longer. In a wet room, the cheaper box that swells in five years is the most expensive box.

How much do the plumber and installer charge?

Labor is the second line and the most variable — it depends on whether the new vanity meets the old plumbing or the plumbing has to move. HomeAdvisor's 2026 data puts plumbers at $45–$200 per hour. For hiring and vetting that labor, see our guide to finding a cabinet installer and the installation cost guide. Expect these bands:

• Like-for-like swap (same width, same drain): roughly $150–$500 — an installer sets and levels the box while a plumber reconnects drain and supplies in an hour or two. Matching the old footprint is how you stay in this cheapest band.
• Standard pro install: roughly $576–$871 per vanity for basic installation labor (Homewyse, May-2026), plus $100–$300 of plumber time for new supply lines, trap alignment, or a faucet set. Most replacements live here.
• Moved drain or new width: roughly $500–$1,000+ in labor. A drain that no longer lands inside the new cabinet means opening the wall and rerouting the waste arm — a half-day plumber visit before the installer starts. Going from a 30-inch single to a 60-inch double often triggers exactly this.
• Removal and disposal: roughly $50–$200 bundled with the install, more as a standalone haul-away. Small-bath demolition overall runs $1,000–$2,300 (HomeAdvisor), so confirm whether a quote covers just the vanity or surrounding tile too.

What do the top, sink, and faucet add?

The cabinet is only the bottom two-thirds of a vanity — the working surface and everything touching water are their own lines. Budget them even when the listing says "top included," because included tops are usually basic cultured marble while upgrades price separately:

• Vanity top: roughly $100–$600 prefab (cultured marble or granite overlay in standard widths) versus $300–$1,000+ for custom-cut quartz or marble with an undermount cutout. Standard 24, 30, 36, and 60-inch widths have prefab options; odd widths pay custom prices.
• Sink: replacing a bathroom sink averages $215–$660 (HomeAdvisor), with statement vessel bowls topping $1,600. Undermount bowls cost more than drop-ins but preserve counter space — worth it on a 30-inch single where every inch works.
• Faucet and hardware: roughly $50–$300 for a single-hole or 4-inch centerset faucet, plus $20–$80 for pulls and knobs. Match the faucet's hole spread to the top before ordering either — an 8-inch widespread on a single-hole top is a reorder, not a workaround.

Should you DIY it or hire a pro?

A like-for-like vanity swap is one of the most DIY-able projects in the house — no wall opened, no drain moved, shutoff valves already in place. Homeowners comfortable with a level, a stud finder, and supply-line connections routinely finish in an afternoon and keep the full $150–$500 swap labor. But the savings evaporate the moment the scope grows: a drain that needs rerouting, a shutoff valve that crumbles when touched, or a wall opened for any reason all convert a $200 Saturday into a plumber's emergency rate plus drywall repair. The honest rule: DIY the swap, hire the move. If the new vanity covers the old footprint and the valves hold, do it yourself; if plumbing changes position, the pro's $45–$200 per hour is cheaper than the second trip to fix a DIY leak.

• DIY saves most when: same width, same drain, working shutoffs, and a prefab top with a pre-drilled faucet spread. Budget $30–$80 in supplies — supply lines, P-trap parts, silicone, shims — and a full afternoon.
• Hire when: the drain moves, valves need replacing, the floor is unlevel enough to need scribing, or the top is stone that needs two people and a perfect set. Get the plumbing and the install quoted as separate lines so each trade competes on its own work.
• Permits: a straight swap rarely needs one; moving a drain or supply inside the wall often does. Your plumber usually knows the local line — ask before the wall opens, not after.

What hidden costs catch vanity budgets off guard?

• Water damage behind the old vanity: roughly $200–$500+ for mold remediation and drywall repair once the box comes off and slow supply-line leaks show themselves. Pad every replacement budget 10–15% for what the wall reveals.
• Floor patching: a narrower new vanity exposes unfinished flooring where the old box sat — $50–$300 for vinyl or tile patching, or a reason to keep the same width. Wider replacements cover old sins; narrower ones bill them.
• Valve and supply replacement: roughly $100–$250 when corroded angle stops or brittle supply lines get replaced while the wall is accessible — cheap insurance against a leak inside a brand-new cabinet.
• Mirror, light, and backsplash ripple: a 60-inch double where a 36-inch single stood usually triggers a wider mirror ($100–$400), repositioned sconces, and a new backsplash run — together easily $300–$800 on top of a "simple" swap.
• Full-remodel context: Angi puts basic bathroom remodels at $2,500–$30,000 — a vanity replacement sits at the light end of that spectrum, which is why it is the highest-ROI way to refresh a tired bath.

How long does a vanity replacement take?

A like-for-like swap takes a pro crew half a day and a DIYer a full afternoon — disconnect in the morning, set and level by lunch, reconnect and caulk by dinner, with silicone curing overnight. Add a day when the drain moves, and a week or more for custom stone, since templating happens only after the new box is set and level. Order the vanity first and schedule trades around its delivery — and confirm your width against the vanity sizes guide before ordering, because a vanity that does not fit turns a one-day swap into a return-and-reorder saga.

Questions homeowners actually ask

How much does it cost to replace a 30-inch bathroom vanity?

Roughly $700–$2,000 all-in: $300–$1,200 for the box, $150–$500 for a like-for-like install and reconnect, plus top, sink, and faucet if not bundled. The 30-inch single is the cheapest width to replace because prefab tops, standard faucets, and standard cutouts all exist for it — no custom line anywhere.

How much does a plumber charge to install a vanity?

Plumbers run $45–$200 per hour (HomeAdvisor 2026 data), and a straightforward reconnect takes one to two hours — budget $100–$400 for the plumbing portion. Full reroutes when the drain moves cost $150–$400+ on top. Confirm whether the installer's quote already includes the reconnect or expects your plumber separately.

Can I replace a vanity without replacing the top?

Sometimes — if the old top is undamaged, the new box matches its exact footprint, and the sink cutout still aligns. In practice, removal cracks stone and cultivates leaks at the old caulk line, so most pros recommend budgeting a new top with every replacement. Prefab tops in standard widths keep that added line near $100–$600.

Is it cheaper to replace or reface a bathroom vanity?

Refacing (new doors and finish on the existing box) costs less when the box is solid and the layout stays — but bathroom boxes often fail from the inside out via moisture, in which case new doors on a swollen box waste the money. If the cabinet floor is soft or the plumbing moves anyway, replace. The kitchen-scale tradeoff is in our refacing vs replacing guide.

Does replacing the vanity increase home value?

It is one of the highest-ROI moves in a bathroom: the vanity dominates the room visually, buyers open its doors, and a $700–$2,000 swap photographs like a remodel costing five times more. Match the vanity's tier to comparable homes in your area, and keep finishes neutral for resale.

Pricing the cabinet line? Browse standard widths in the vanity catalog — every size from powder-room 24-inch singles to 60-inch doubles — and confirm your width against the vanity sizes guide before requesting numbers. Cabinetry is the one line you can pin down exactly before any trade visits.
