Average Bathroom Vanity Replacement Costs by Size
Vanity replacement costs are heavily dictated by width and the number of plumbing rough-in connections. Below are average national contractor pricing benchmarks:
| Vanity Size | Configuration | Unit & Top Cost | Plumber Labor | Total Installed Cost |
|---|---|---|---|---|
| 24″ – 30″ | Single Basin (Powder Room) | $200 – $550 | $150 – $300 | $350 – $850 |
| 36″ | Single Basin (Full Bath) | $350 – $850 | $200 – $400 | $550 – $1,250 |
| 48″ | Single Basin (Master/Guest) | $550 – $1,350 | $250 – $500 | $800 – $1,850 |
| 60″ | Double Basin (Dual Sink) | $900 – $2,200 | $400 – $850 | $1,300 – $3,050 |
| 72″+ | Double Basin (Custom Luxury) | $1,500 – $3,800 | $550 – $1,100 | $2,050 – $4,900 |
Major Cost Factors to Keep in Mind
- Wall-Hung Floating Vanities: Floating cabinets cannot simply be screwed into drywall anchors. They require opening the wall to install 2×6 or 2×8 structural solid wood blocking between studs, increasing labor by $180 to $350.
- Single-to-Double Sink Conversions: Splitting one water supply into two requires extending copper or PEX tubing and installing a dual sanitary drainage tee inside the wall cavity, adding $400 to $900 in licensed plumbing labor.
- Footprint Mismatches: If your new vanity is narrower or shallower than your previous vanity, you will likely expose unfinished subfloor or missing baseboard trim. Consider retiling or using our Tile Calculator to plan a floor refresh.
Frequently Asked Questions
The national average cost to replace a bathroom vanity ranges from $500 to $2,800, with most homeowners spending roughly $1,350 for a mid-sized 36-to-48 inch single vanity including professional installation. Small powder room vanities (24 inches) can cost as low as $350 to $700, while high-end double vanities (60 to 72 inches) with custom quartz or marble tops typically cost between $1,800 and $4,500.
Labor costs generally range from $200 to $650 for standard installations. A general handyman typically charges $50 to $85 per hour (2 to 4 hours of work), while a licensed plumber charges $85 to $150 per hour. If you require drywall repairs, structural blocking for a floating vanity, or moving drain and water lines inside the wall, labor can increase to $800 to $1,500.
Converting a single sink vanity to a double vanity typically adds $400 to $900 in plumbing labor and materials. A plumber must open the drywall to extend the existing hot and cold water supply lines and install an additional waste drain pipe (sanitary tee and second P-trap) to accommodate two independent sinks.
Yes, replacing a freestanding vanity with the same size and plumbing layout is an achievable intermediate DIY project that can save $250 to $600 in labor. You will need basic plumbing tools, silicone caulk, teflon tape, and helper assistance to lift heavy stone countertops. However, installing heavy floating (wall-hung) vanities or relocating water lines is best handled by licensed pros.
Not necessarily, but choosing a smaller vanity or different base style will often expose unpainted drywall and raw subfloor where the previous vanity sat. If you downsize, budget $150 to $400 for flooring patches, baseboard trim, and sheetrock painting, or ensure your new vanity is equal to or slightly larger than the original footprint.
