Quick Answer
Angi reports bathroom vanity installation at about $400 to $2,200 in 2026. The finished bill can be higher when the project includes old-vanity removal, a stone top, sink and faucet changes, new shutoff valves, plumbing relocation, wall repair or custom cabinetry.
Home Cost Desk uses national cost data as planning guidance rather than a substitute for a local written bid. Actual prices vary with city, labor market, product availability, building age, access, code requirements and concealed damage.

How to Read the Price Range
Angi’s $400–$2,200 range spans a prefabricated vanity with an integrated top dropped into the same spot and a larger semi-custom cabinet with a separate stone top. Prices climb when the new vanity is a different width or depth than the old one, when plumbing has to move, when the floor or wall behind the old cabinet needs repair, or when removal of the old vanity (about $150–$500 per Angi) is not included.
What Drives the Cost
The largest cost drivers for this project include vanity width and number of sinks, prefabricated versus semi-custom/custom cabinet, countertop material, integrated top versus separate sink, faucet and drain changes, plumbing alignment, wall/floor condition behind old cabinet, and backsplash and mirror work.
Hidden Costs to Budget For
Build a contingency for conditions that cannot be fully confirmed until work begins. Common examples include painting behind a differently sized vanity, baseboard or flooring gaps, new shutoff valves and supply lines, countertop fabrication and sink cutouts, electrical relocation for outlets or sconces, and disposal of old cabinet and top.
Safety, Permits and Quality Control
Shut off water and confirm valves hold before disconnecting plumbing. Large stone tops are heavy and brittle. If a wider vanity conflicts with electrical outlets or clearances, do not improvise around the problem; coordinate trades and local code requirements.
A vanity project is a natural time to replace the faucet. WaterSense-labeled bathroom faucets use no more than 1.5 gallons per minute, which EPA says can reduce sink water flow by 30 percent or more from the standard 2.2 gallons per minute without sacrificing performance (EPA WaterSense bathroom faucets).
Permit rules vary by jurisdiction. The contractor should state whether a permit is required and who will obtain it. For work involving structure, plumbing, electrical systems, combustion equipment, waterproofing or the weather envelope, quality control belongs in the scope from the beginning.
Three Real-World Planning Scenarios
Scenario 1: Same-size prefab vanity
Keeping plumbing and footprint in place is the most budget-predictable replacement.
Scenario 2: Double vanity replacing a single
New drain and supply routing can make plumbing the major cost driver.
Scenario 3: Floating vanity
Wall blocking, plumbing placement and finished flooring beneath the cabinet matter more than with a standard floor-mounted unit.
How to Compare Contractor Quotes
Compare vanity bids on who supplies the cabinet, top and faucet, whether the plumbing will need to move to fit the new cabinet, and how flooring and wall gaps left by the old vanity will be handled. A larger or differently shaped vanity can expose unfinished floor or wall areas.
DIY vs. Professional Vanity Replacement
A like-for-like vanity swap can be a reasonable DIY project when the cabinet fits the existing space, the countertop and sink are preassembled, and the drain and supply lines remain in the same locations. The risk rises quickly when plumbing must move, the countertop needs field cutting, shutoff valves are corroded or wall and floor repairs appear after demolition.
If you are doing part of the work yourself, agree with the plumber or installer on the handoff point before removal. A professional should handle any work that requires opening walls, relocating supply or drain lines, repairing active leaks or correcting unsafe electrical conditions near the vanity. Test every connection for leaks before the cabinet is loaded and the project is considered complete.
How to Save Money Without Creating a False Economy
Choosing a vanity with the same width and plumbing layout as the old one avoids flooring patches and plumbing changes. A prefabricated vanity with an integrated top is usually less expensive than a separate custom top. If you buy the vanity yourself, confirm dimensions and drain location with the installer before ordering.
Pre-Quote Homeowner Inspection
- Measure the current vanity width, depth and height, and the location of the drain and supply lines.
- Check under the sink for water damage or soft flooring.
- Note whether flooring runs under the old vanity or stops at its base.
- Check the shutoff valves for leaks or stiffness.
Red Flags in a Quote
- No plan for flooring or wall repair where the old vanity sat.
- Reusing old shutoff valves without checking them.
- A price that does not say who supplies the top and faucet.
- No plan for likely concealed conditions such as painting behind a differently sized vanity, baseboard or flooring gaps, new shutoff valves and supply lines, countertop fabrication and sink cutouts.
Planning the Work From Start to Finish
Shut off water at the valves and confirm they hold before demolition. After installation, check the drain and supply connections for drips over the next few days and confirm the vanity is anchored.
Quote Checklist
- Vanity, top and faucet models and who supplies them.
- Plumbing changes to fit the new cabinet.
- Shutoff valves and supply lines.
- Floor, wall and backsplash repair.
- Disposal of the old vanity.
- Demolition, removal and disposal.

Frequently Asked Questions
Can a new vanity use the existing plumbing?
Often, if the drain and supply locations line up with the new cabinet. Moving plumbing adds cost.
Should I replace the faucet at the same time?
It is often convenient. A WaterSense-labeled faucet uses no more than 1.5 gallons per minute.
What if the floor under the old vanity is damaged?
Ask for a separate price to repair the subfloor and flooring before the new vanity is set.
Vanity Replacement Planning Checklist
- Measure wall width, depth, door clearance and plumbing locations before choosing the cabinet.
- Confirm whether the new vanity keeps the existing drain and supply positions or requires plumbing relocation.
- Ask whether the quote includes cabinet removal, countertop, sink, faucet, drain, shutoff valves, backsplash, caulk and wall or floor patching.
- Check whether the old vanity hides water damage, uneven flooring or missing wall finish that will need repair once removed.
- Before final payment, verify doors and drawers clear nearby fixtures, the sink drains correctly and all plumbing connections remain dry.
What to Do Next
- Measure the existing vanity, plumbing locations and available clearance before selecting a replacement cabinet and top.
- Get written bids that separate cabinet, countertop, sink, faucet, plumbing changes, demolition, wall repair and finish work.
- Confirm shutoff-valve condition and any hidden water damage before final installation so change orders are documented rather than assumed.
Choose the vanity size only after measuring the room and existing plumbing. Comparable bids should state whether the countertop and sink arrive preassembled, who supplies the faucet and drain parts, and how any wall, floor or plumbing repair will be priced.
Bottom Line
Angi reports bathroom vanity installation at about $400 to $2,200 in 2026. The finished bill can be higher when the project includes old-vanity removal, a stone top, sink and faucet changes, new shutoff valves, plumbing relocation, wall repair or custom cabinetry. The strongest decision is based on the real project scope, a normalized written quote and clear responsibility for preparation, hidden conditions and finish work.
