What affects the cost?

  • Vanity grade and material — builder/retail-grade units run $250-$500 installed, mid-grade $600-$1,500, and designer-grade $2,000-$3,800, with fully custom cabinetry reaching $1,000-$4,000 (Inch Calculator, HomeGuide)
  • Vanity length/size — HomeAdvisor's size table shows a 2.5-ft single vanity at $100-$500 installed climbing to $800-$2,100 for a 6-ft single vanity, and $550-$2,200 for 4-5 ft double-sink units (HomeAdvisor)
  • Single vs. double sink — a single-sink vanity typically runs $200-$1,500 (up to $5,000 for high-end units), while a double-sink vanity runs $1,000-$1,500 and can reach $10,000 because of the extra plumbing connections required (Inch Calculator)
  • Countertop material — granite runs about $5-$100 per sq ft vs. quartz at $50-$200 per sq ft (HomeAdvisor); This Old House similarly lists quartz around $75/sq ft and laminate around $53/sq ft
  • Removing the old vanity — typically $115-$500 (HomeAdvisor) or $150-$450 including haul-away (Inch Calculator)
  • New or relocated plumbing — running new supply/drain lines averages $400-$2,000 (HomeAdvisor), or $300-$400 for a straightforward hookup (Inch Calculator); hiring a plumber runs $45-$200 per hour (HomeAdvisor)
  • Backsplash addition — about $1.50-$30 per sq ft depending on material (HomeAdvisor, This Old House)
  • General contractor oversight — Homewyse notes GC supervision can add 13%-22% to the estimate

Why does bathroom vanity installation cost so much?

The price mostly comes down to vanity grade, size, and how much plumbing work is involved. Installing a bathroom vanity typically costs $300 to $3,800, averaging around $1,900 nationally, though sources disagree on the exact average: HomeAdvisor cites $1,500, This Old House $1,983, and Inch Calculator $2,300 (HomeAdvisor, This Old House, Inch Calculator). At the low end, a builder/retail-grade prefab unit installs for $250-$500, while a designer-grade vanity runs $2,000-$3,800 (Inch Calculator) and a fully custom build runs $1,000-$4,000 (HomeGuide). Sink count matters too — a single-sink vanity typically costs $200-$1,500, but a double-sink vanity runs $1,000-$1,500 and can climb to $10,000 because of the added plumbing connections (Inch Calculator). Vanity length also scales cost directly: HomeAdvisor’s size table shows a 2.5-ft single vanity at $100-$500 climbing to $800-$2,100 for a 6-ft single vanity.

What affects the cost?

A handful of variables explain most of the gap between a $500 swap and a $3,800+ remodel:

  • Vanity grade and material. Builder/retail-grade units run $250-$500 installed, mid-grade $600-$1,500, and designer-grade $2,000-$3,800; fully custom cabinetry can reach $1,000-$4,000 (Inch Calculator, HomeGuide).
  • Vanity length. HomeAdvisor’s size breakdown runs from $100-$500 for a 2.5-ft single vanity up to $800-$2,100 for a 6-ft single, and $550-$2,200 for 4-5 ft double-sink units.
  • Single vs. double sink. A double-sink vanity ($1,000-$1,500, up to $10,000) costs more than a single-sink vanity ($200-$1,500, up to $5,000) mainly because of the extra plumbing it requires (Inch Calculator).
  • Countertop material. Granite runs $5-$100 per sq ft and quartz $50-$200 per sq ft (HomeAdvisor); This Old House similarly lists laminate around $53 per sq ft against quartz around $75 per sq ft.
  • Old vanity removal. Tearing out and hauling away the existing vanity adds $115-$500 (HomeAdvisor) or $150-$450 (Inch Calculator).
  • New or relocated plumbing. Running new supply/drain lines averages $400-$2,000 (HomeAdvisor), or $300-$400 for a simple hookup (Inch Calculator); a plumber alone runs $45-$200 per hour.
  • Backsplash. Adding one costs roughly $1.50-$30 per sq ft depending on material (HomeAdvisor, This Old House).
  • General contractor oversight. Homewyse notes that GC supervision can tack on 13%-22% to the total estimate.

How to lower your bathroom vanity installation cost

  • Stick with a premade, builder-grade unit instead of custom cabinetry. The gap between a $250-$500 stock vanity (Inch Calculator) and a $1,000-$4,000 fully custom build (HomeGuide) — or a $2,000-$3,800 designer-grade build (Inch Calculator) — is one of the biggest levers in this project.
  • Keep the plumbing footprint the same. Reusing your existing supply and drain locations can keep plumbing costs near the $300-$400 low end instead of the $400-$2,000 range for relocated lines (HomeAdvisor, Inch Calculator).
  • Choose a laminate or solid-surface top over stone if budget is tight — laminate runs around $53 per sq ft versus $75+ per sq ft for quartz (This Old House).
  • Skip the double-sink upgrade unless you need it. A single-sink vanity avoids the extra plumbing connections that push double-sink jobs toward $1,000-$10,000 (Inch Calculator).
  • Ask about removal separately. Since old-vanity removal is usually a distinct $115-$500 line item, confirm whether your quote already includes it before assuming a bundled price (HomeAdvisor).
  • Get multiple quotes, since national averages alone span from about $1,500 to $2,300 depending on the source — local bids will tell you where your specific project actually lands.

Prices vary by region, vanity size, and material grade, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether removal, plumbing changes, and countertop material are included, before committing to a final number.

Frequently asked questions

How much does it cost to install a bathroom vanity?
Nationally, installation runs $300 to $3,800, averaging about $1,900. HomeAdvisor puts its typical range at $300-$2,200 (average $1,500), while This Old House and Inch Calculator report higher averages of $1,983 and $2,300, reflecting a mix of basic swaps and full custom jobs in their data.
How much does it cost to install just a premade vanity?
A premade or stock vanity typically installs for $400-$1,700, and a small builder/retail-grade unit can run as little as $250-$500 (HomeGuide, Inch Calculator).
Is a double-sink vanity more expensive to install than a single-sink one?
Yes. A single-sink vanity typically runs $200-$1,500 (up to $5,000 for premium units), while a double-sink vanity runs $1,000-$1,500 and can reach $10,000, largely because of the extra plumbing connections it needs (Inch Calculator).
Does the price include removing the old vanity?
Usually not as a default line item. Removal and haul-away typically costs $115-$500 (HomeAdvisor) or $150-$450 (Inch Calculator) and is often quoted separately from the new installation.
How much does the countertop add to the cost?
It depends heavily on material. Granite runs about $5-$100 per sq ft and quartz $50-$200 per sq ft (HomeAdvisor); This Old House lists laminate around $53 per sq ft and quartz around $75 per sq ft. Swapping a laminate top for stone can add hundreds of dollars to the job.
What if my new vanity needs new plumbing?
Running new supply and drain lines averages $400-$2,000 (HomeAdvisor), or as little as $300-$400 for a straightforward hookup with a plumber nearby (Inch Calculator). Keeping your new vanity's plumbing footprint close to the old one keeps this cost down.

  • HomeGuide — Quoted from Google's indexed search snippet (direct page fetch returned HTTP 403): average cost to install or replace a bathroom vanity is $400 to $1,700 for premade models or $1,000 to $4,000 for a custom vanity. Vanity prices $300-$3,000 for the unit alone and $100-$1,000 for labor. Premade vanity unit alone $300-$1,500 depending on size, brand, and quality.

Source-stated national averages vary widely: HomeAdvisor reports $1,500 (typical range $300-$2,200), This Old House reports $1,983 (range $665-$3,300), and Inch Calculator reports $2,300 (typical range $300-$3,800). Homewyse's cost-calculator figure ($576-$871) is narrower still because it covers only a basic-grade vanity swap with favorable site conditions and existing plumbing, not a full remodel-style installation. The national_average_usd figure ($1,900) is a synthesized rounded mean of the three source-stated averages (HomeAdvisor $1,500, This Old House $1,983, Inch Calculator $2,300 -- raw mean ~$1,928). range_low_usd/range_high_usd ($300-$3,800) use Inch Calculator's explicitly stated 'Typical Price Range,' which is consistent with HomeAdvisor's and HomeGuide's $300 low end and close to This Old House's $3,300 high end; fully custom builds can exceed this (HomeGuide cites custom vanities up to $4,000, and double-sink units up to $10,000 per Inch Calculator). HomeGuide's homeguide.com/costs/bathroom-vanity-installation-cost page returned an HTTP 403 on direct fetch, so its figures here are quoted from Google's indexed search snippet of that page rather than a full page fetch; all other sources were fetched directly. Figures generally cover the vanity unit, basic installation labor, and job supplies; old-vanity removal, new/relocated plumbing, backsplash, and countertop upgrades are frequently billed as separate line items rather than bundled into the base price -- see cost_factors for those add-on ranges. The by_type single-sink ($200-$1,500) and double-sink ($1,000-$1,500) rows use Inch Calculator's stated 'typical' ranges only; Inch Calculator's separate 'up to $5,000' (single-sink) and 'up to $10,000' (double-sink) ceilings for premium/plumbing-heavy jobs are called out in cost_factors rather than folded into the by_type low-high pair.
