What Drives the Price
Understanding these key factors will help you estimate your costs more accurately and know what to expect when getting quotes.
1. Vanity Material
Solid wood dries well; particle board fails quickly.
Example: Solid wood repair: $400. Particle board replacement: $800+.
2. Countertop Type
Laminate is cheapest to replace; stone costs more.
Example: Laminate: $50–$150. Granite: $400–$800.
3. Subfloor Condition
Water around toilets and vanities often damages subfloor.
Example: Subfloor replacement adds $300–$800.
4. Custom Size
Non-standard vanity sizes require custom work.
Example: Stock 30": $400. Custom 45": $1,500+.
5. Plumbing Modifications
Different vanities may need plumbing adjustments.
Example: Plumbing relocation: $200–$500.
Vanity Damage Is Usually a Symptom, Not the Main Event
A water-damaged bathroom vanity is rarely an isolated repair; by the time the vanity cabinet shows visible swelling, the flooring beneath it and often the wall behind it have usually absorbed water too, since bathrooms concentrate moisture in a tight footprint.
What's actually included when a vanity gets replaced
Replacing just the vanity cabinet and top is the cheapest part of this repair. Once the old vanity is pulled, contractors routinely find the flooring underneath (especially vinyl or laminate) has also swelled or lifted, and the wall behind the vanity, if it's drywall rather than tile, often needs to come out too if the leak was slow and ongoing rather than a one-time event.
Plumbing rough-in location can limit your replacement options
If the original leak came from supply lines or drain plumbing inside the vanity cabinet, that plumbing typically needs repair or replacement as part of the same job, and the rough-in locations for those lines can constrain which replacement vanity sizes and styles will actually fit without additional plumbing work. Get the plumbing addressed and confirmed before ordering a new vanity, so you're not stuck reworking supply lines a second time to fit cabinetry you already bought.
