What Drives the Cost
Vanity Size and Type
$200 - $5,000+A basic 24-inch stock vanity with an integrated top runs $200-$500. A 48-inch single-sink vanity with a separate countertop costs $500-$1,500. A 60-72 inch double vanity pushes $800-$3,000 for the cabinet alone. Custom or floating vanities from specialty manufacturers start at $2,000 and climb from there.
Countertop Material
$100 - $2,500Integrated cultured marble or laminate tops cost $100-$300. A granite or quartz top for a single vanity runs $300-$800. Custom stone tops for a double vanity cost $600-$1,500. Marble and specialty materials push $1,000-$2,500. The countertop often costs as much as the cabinet itself.
Plumbing Modifications
$0 - $1,500Swapping a vanity in the same footprint with compatible plumbing connections costs nothing extra for plumbing. Changing from a deck-mounted faucet to a wall-mounted one requires opening the wall - add $400-$800. Relocating supply and drain lines for a different vanity size adds $600-$1,500.
Single vs. Double Vanity
$500 - $3,000 differenceUpgrading from a single to a double vanity roughly doubles your material cost and adds plumbing for the second sink. A double vanity also requires a wider countertop, a second faucet ($100-$500), and potentially a second mirror. Total add-on for the double conversion runs $1,000-$3,000 beyond the single-vanity price.
Installation Complexity
$150 - $800A basic drop-in vanity replacement takes a plumber 2-3 hours at $150-$350. A wall-mounted floating vanity requires securing a mounting bracket to wall studs and often adjusting drain height - expect $400-$600 in labor. Adding under-cabinet lighting or electrical outlets pushes installation to $500-$800.

Timeline & What to Expect
DIY vs. Professional
Good for DIY
- Remove old vanity
- Install new stock vanity cabinet
- Connect faucet supply lines (compression fittings)
- Install new mirror
- Caulk around countertop and backsplash
Potential savings: 50-70%
Hire a Pro
- Relocate plumbing supply or drain lines
- Install wall-mounted faucet (requires opening wall)
- Mount floating vanity to studs with proper blocking
- Custom stone countertop templating and installation
- Electrical work for new outlets or under-cabinet lighting
DIY feasibility: High
Risk warning: The most common DIY mistake is cross-threading supply line connections or failing to properly tighten drain fittings, which causes slow leaks under the vanity that go unnoticed for weeks. Water damage to the cabinet bottom and flooring below can cost $500-$2,000 to fix. Always test all connections with the water on for 15 minutes before closing up the cabinet.
How to Save Money
Buy a stock vanity with an integrated top. One-piece vanities from Home Depot or Lowe's run $200-$600 and eliminate the separate countertop cost entirely.
Keep the same vanity footprint. Swapping a 36-inch vanity for another 36-inch avoids wall patching, floor repair, and plumbing modifications.
Shop clearance and floor models. Kitchen and bath showrooms sell display vanities at 30-50% off. These are typically in great condition with minor cosmetic wear.
Install it yourself if it is a simple swap. A basic vanity replacement with accessible plumbing is one of the more approachable bathroom DIY projects - you save $250-$600 in labor.
Refinish instead of replacing. If your vanity cabinet is solid wood in good condition, painting it ($50-$150 in materials) and adding a new countertop ($150-$500) costs far less than a full replacement.
Skip the custom stone top. A prefabricated quartz or cultured marble top for standard vanity sizes costs $150-$400 vs. $600-$1,500 for a custom-templated stone top.
Reuse your existing faucet if it is in good shape. A quality faucet that fits your new vanity saves $100-$400.
Questions to Ask Your Contractor
“Will you handle any wall or floor patching needed after removing the old vanity?”
Why this matters: Old vanities often leave gaps in flooring or wall damage. Confirm this is included in the quote so you are not surprised by extra charges.
“Do I need any plumbing modifications for the new vanity I have selected?”
Why this matters: Different vanity sizes and sink configurations may need drain or supply line adjustments. This is the biggest variable cost, so get it confirmed upfront.
“How will you handle the drain connection if the new vanity has a different cabinet depth?”
Why this matters: A shallower vanity may require repositioning the P-trap or using an extension. A deeper one may need a shorter tailpiece. Both affect cost.
“Is disposal of the old vanity included in your price?”
Why this matters: Hauling away an old vanity and countertop can add $50-$150 if not included. Some contractors leave it for you to deal with.
“Will you install the faucet, mirror, and lighting, or just the vanity?”
Why this matters: Some plumbers only handle the vanity and plumbing connections. You may need a separate handyman or electrician for the mirror, lighting, and accessories.
“What warranty do you offer on the plumbing connections?”
Why this matters: Leaks from improperly connected supply lines or drains cause water damage. Make sure the installer stands behind their work for at least one year.
