Cost to Install a Double Sink Vanity
Installing a double sink vanity means removing the old cabinet, positioning and leveling the new one, securing it to wall studs, and connecting the faucet and drain assembly, water supply lines, and P-trap assembly. The work is moderately difficult because the unit must fit the available space and plumbing rough-in locations while the floor and wall need to be level and plumb.
Common reasons homeowners do this job
- An existing vanity is worn or damaged.
- A bathroom upgrade includes adding a double sink vanity.
- The old vanity cabinet is being removed and damaged wall or floor areas need repair.
- A new vanity is needed that fits the available space and matches the plumbing rough-in locations.
DIY or call a pro?
This is a DIY-friendly project, but a professional is worth considering if you are uncomfortable disconnecting supply lines and drain pipes, securing a cabinet to wall studs, or connecting the P-trap and new plumbing. Keep the water supply completely shut off while working, use caution when handling the heavy vanity unit, and verify that every plumbing connection is leak-free after installation.
Frequently asked questions
- Is installing a double sink vanity a DIY project or a job to hire out?
- It is a DIY-friendly, moderate project for someone comfortable measuring the space, leveling a cabinet, working with wall studs, and reconnecting plumbing. Consider professional help if any of those steps are unfamiliar, especially the plumbing connections. Shut off the water completely before starting, handle the vanity carefully because it is heavy, and check for leaks when the connections are complete.
- What can make double sink vanity installation cost more?
- The price can increase with the job size and number of vanity units, the labor time involved, and the materials selected. Haul-away of 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 check before buying a double sink vanity?
- Measure the available space first, then select a vanity that matches the existing plumbing rough-in locations. Also verify that the floor and wall are level and plumb, since the cabinet needs to sit level before it is secured to the wall studs.
- What needs to be checked after the vanity plumbing is connected?
- After connecting the faucet and drain assembly, water supply lines, and P-trap assembly, verify that the plumbing connections are leak-free. Silicone sealant is applied along the edges where the vanity meets the wall.
