Cost to Install a Bathroom Vanity
Installing a bathroom vanity means removing the old cabinet, top, and P-trap; setting and anchoring a new cabinet; then fitting the countertop, faucet, supply lines, and drain. The work combines carpentry and basic plumbing, and the challenge is getting the cabinet level against an uneven wall while lining it up with the existing supply and drain rough-ins.
Common reasons homeowners do this job
- A worn or damaged vanity cabinet or top needs replacement.
- A bathroom update calls for a new vanity, faucet, or sink setup.
- The existing vanity is a poor fit for the available space.
- A new cabinet needs to align with the existing water supply and drain rough-ins.
- The old vanity is being removed as part of a bathroom refresh.
DIY or call a pro?
This is a DIY-friendly job if you are comfortable with basic plumbing and carpentry. Consider professional help if you are unsure about locating wall studs, shimming the cabinet level, anchoring it through the back rail, or connecting the supply lines and P-trap. Shut off the water before disconnecting anything, and check behind the old vanity for hidden water damage before installing the new one.
Frequently asked questions
- Can I install a bathroom vanity myself, or should I hire someone?
- A homeowner can take this on when they can measure the space and rough-in locations, level and shim the cabinet, anchor it to wall studs, and make the faucet and drain connections. Consider professional help when any of those steps feels uncertain, especially if the cabinet rocks or leans against the wall.
- What makes bathroom vanity installation cost more?
- The price can rise with the job size, labor time, and the materials selected. Removing and hauling away the old vanity can also add to the job, and a small installation may be affected by a minimum or trip charge.
- What should I measure before buying a new bathroom vanity?
- Measure the available space and the locations of the existing water supply and drain rough-ins so the cabinet fits over them. Also locate the wall studs before installation, since the cabinet anchors through its back rail.
- Should the faucet and drain be installed before setting the vanity top?
- Install the faucet and drain on the sink before setting the top, since those connections are easier to make while the top is off the wall. Once the top is set, connect the supply lines and P-trap, turn the water back on, and check every joint for leaks.
