How to Install a Bathroom Vanity

Transform the look of your bathroom with a new vanity

The vanity is the centerpiece of your bathroom, and it serves important aesthetic and practical functions. While vanities come in all shapes and sizes, from narrow units which provide a housing for your sink to elaborate, full-sized furnishings with drawers, cabinets and generous counter space, the basic installation process is the same. You will need the following supplies:

  • Tape measure
  • Screwdriver
  • Wood screws (3-inch size)
  • Hammer
  • Finishing nails
  • Shims

Installing a Bathroom Vanity

Your bathroom vanity installation can be completed in seven steps:

  1. Make sure you have accurate height, width and depth measurements before finalizing the purchase of your new vanity. In most bathrooms, space is at a premium, so even slight miscalculations can cause major headaches.
  2. Remove the cabinet doors from your new vanity prior to installation, to protect them from potential damage during the installation process.
  3. Remove your sink, faucets and any other plumbing fixtures.
  4. Slide your vanity into position. Check to make sure it's level; use shims to get it straight if you need to make any adjustments or corrections.
  5. Install your wood screws on the back of the cabinet, through the vanity's nailer holes. Screw them into place with your screwdriver.
  6. Reinstall the cabinet doors once the vanity is in its final position and fully level. If necessary, seal the gap between the vanity and the wall with caulking.
  7. Reinstall the sink and plumbing fixtures.

If you're going to replace your sink and fixtures in addition to your vanity, be sure to select these components first so you can get a vanity that will house them correctly. While it is possible to adjust the vanity's sink allowance, this is a more advanced task that requires particular skill and expertise, and it is not recommended for novice to intermediate do-it-yourselfers.

Finally, a safety note: vanities are heavy, so don't try to complete this task on your own unless the vanity is lightweight and compact. Otherwise, you could damage the vanity or injure yourself. Enlist the help of another person so that the vanity can be easily and accurately placed in its proper position.
