Step 6: Set and Fasten the Vanity

  • Measure the vanity cabinet’s height and transfer the dimension to the sidewall. Then, draw a straight line using a level at the marked height.
  • Now, place your vanity cabinet in its proper position.
  • Using the line you’ve drawn, check if the cabinet is in level both front-to-front and side-to-side. You can use wood shims or vanity feet to level it.

Step 7: Secure Vanity to the Wall
