Replacing a bathroom vanity typically costs $400–$4,000* for the vanity and installation, depending on whether you choose a prefabricated or custom unit. A straightforward replacement that uses your existing plumbing will generally cost less than a larger vanity with custom cabinetry, a separate countertop, or plumbing changes.
*All cost estimates on this page are planning estimates, not quotes. Actual costs vary by location, project scope, materials, site conditions, and contractor. See methodology and sources.
For a standard prefabricated bathroom vanity, homeowners can expect to spend approximately $400–$1,700 installed. Custom vanities can cost $1,000–$4,000 or more.
The biggest cost difference usually comes down to the vanity itself and how much work is needed to install it. Keeping the new vanity in the same location and reusing the existing plumbing layout can help keep the project more affordable.
The cost of replacing a bathroom vanity depends on the type of cabinet you choose and what's included in the installation.
| Vanity Replacement Type | Estimated Installed Cost* | What's Included |
|---|---|---|
| Prefabricated vanity | $400–$1,700 | Standard vanity unit with basic installation |
| Custom vanity | $1,000–$4,000 | Custom cabinetry and installation; costs vary by design and materials |
Planning ranges based on published national estimates. The price of sinks, faucets, countertops, removal, and plumbing changes may be included or charged separately depending on the product and contractor.
A larger vanity generally costs more, especially if you're adding a second sink.
| Vanity Size | Estimated Unit Cost* |
|---|---|
| 30-inch single vanity | $100–$500 |
| 48-inch single vanity | $400–$700 |
| 60-inch single vanity | $500–$1,500 |
| 60-inch double vanity | $600–$2,000 |
| 72-inch double vanity | $1,000–$2,000 |
These are approximate prices for prefabricated vanity units, not complete installed project costs. Prices vary by materials, configuration, and included components.
If you're replacing a single vanity with a double, ask whether the existing plumbing can accommodate two sinks. Adding another sink may require additional supply and drain connections.
The vanity you choose is only part of the total price. Before ordering one, it's worth understanding how the installation could affect your budget.
A basic 30-inch vanity typically costs less than a 60-inch double vanity. Larger cabinets use more materials, and certain designs may require additional installation work.
Wall-mounted or floating vanities can also be more involved to install than traditional floor-standing cabinets. The wall needs adequate support, and exposed plumbing may need to be repositioned or updated.
Prefabricated vanities are usually the most budget-friendly choice. They're available in standard sizes and often come with a countertop and sink already included.
Custom cabinetry gives you more flexibility with dimensions, storage, and finishes, but it also increases the price.
Countertops matter, too. Laminate and some integrated vanity tops tend to be more affordable, while quartz, granite, and other premium materials can raise the total cost.
Before comparing prices, check whether the vanity includes the countertop, sink, and faucet. Two similarly priced cabinets may come with very different components.
Keeping your sink in the same location is one of the simplest ways to control installation costs.
If the new vanity has a different sink configuration or the drain doesn't line up with the cabinet, your contractor may need to modify the plumbing.
This is especially important when switching from a single sink to a double vanity or installing a floating vanity with exposed plumbing.
Removing an old vanity may reveal problems that weren't visible before, such as water-damaged drywall, deteriorated flooring, or a leaking supply connection.
These repairs aren't always included in the initial estimate. Ask how your contractor handles additional work and whether you'll approve the cost before repairs begin.
Installation prices vary depending on where you live and the type of work involved. A straightforward vanity swap may require relatively little labor, while plumbing modifications, countertop installation, or wall repairs can add time and expense.
Comparing local quotes is the best way to understand what your specific project will cost.
Before choosing a contractor, make sure you understand what you're paying for. A vanity installation quote should explain which materials and services are included and which will cost extra.
| Component | What to Check |
|---|---|
| Vanity cabinet | Confirm the brand, size, material, and finish of the unit being installed. |
| Countertop and sink | Check whether they're included with the vanity or purchased separately. |
| Faucet and drain hardware | Find out whether new fixtures are included and who will install them. |
| Removal and disposal | Ask whether the contractor will remove and haul away your existing vanity. |
| Plumbing connections | Confirm whether disconnecting and reconnecting the sink is included. |
| Installation | Make sure the quote covers securing and leveling the vanity, sealing where appropriate, and checking for leaks. |
| Wall and flooring repairs | Ask whether any patching or repairs are included if the new vanity has a different footprint. |
| Additional work | Find out how unexpected repairs or plumbing modifications will be priced and approved. |
One detail worth checking: A vanity sold as a complete set may include the cabinet, countertop, and sink but not the faucet or drain assembly. Review the product specifications before ordering so you don't overlook anything needed for installation.
Yes. If the existing bathroom layout works well, replacing the vanity can be a relatively simple update without renovating the entire space.
A new vanity can give you more storage, replace a damaged cabinet, or make the bathroom feel more current. You may be able to keep the existing flooring, mirror, lighting, and plumbing layout.
The easiest replacement is usually one that fits the same footprint as the old vanity. If you choose a smaller cabinet, previously hidden flooring or unfinished wall surfaces may become visible. A larger cabinet can interfere with outlets, doors, or nearby fixtures.
Measure the available space carefully before shopping, including the location of the plumbing and the clearance needed to open drawers and cabinet doors.
If you're planning to replace the flooring, shower, or other fixtures soon, it may make sense to coordinate the work as part of a larger project. See our bathroom remodel cost guide to compare the potential scope and expense.
Replacing a bathroom vanity can be a manageable DIY project for homeowners who are comfortable with basic installation and plumbing connections.
However, even a straightforward swap involves disconnecting the water supply, removing the existing cabinet, fitting the new vanity, and reconnecting the sink without leaks.
A professional is worth considering when:
If you plan to handle the installation yourself, confirm the vanity's dimensions, plumbing compatibility, and installation requirements before purchasing it.
For work involving plumbing modifications or electrical changes, check local requirements and use appropriately qualified professionals.
A straightforward bathroom vanity replacement can often be completed in a day when the new unit fits the existing space and plumbing connections don't need major changes.
Projects involving custom countertops, plumbing relocation, or wall and flooring repairs may take several days or require separate visits.
Custom cabinetry can also have a longer lead time before installation begins.
Ask your contractor whether the vanity and countertop will be available before scheduling the work. This can help prevent a situation where the old vanity is removed but the replacement isn't ready to install.
You don't necessarily need custom cabinetry or an entirely new bathroom layout to get a vanity that works better for your space.
If your existing cabinet is structurally sound and you mainly want a different appearance, refinishing it or replacing the countertop may also be worth pricing before committing to a full replacement.
Getting more than one estimate can help you understand local pricing, especially if your project involves more than a simple cabinet swap.
When reviewing quotes, pay attention to the details rather than just the final number.
Make sure the scope is in writing before work begins. If you're comparing two contractors, ask each to price the same materials and installation requirements.
