How To Install A Wall-Mount Sink


how to install a wall mount sink
We recommend consulting a professional if you are unfamiliar with installing bathroom fixtures.
Because wall construction and materials vary from home to home, the appropriate mounting hardware may need to be purchased from your local hardware store.
For the following installation instructions it is assumed that any old fixtures have been removed and that the water supply lines and drain pipe are in place.
Tools and Materials:


Crescent Wrench

Basin Wrench

Socket Wrench




Mounting Hardware

Stud Finder
   Step 1  
  Place the mounting plate in the installation location and mark the wall through each of the mounting holes. If there is no mounting plate, use the holes in the back of the sink basin as your template.

Important: The sink should be anchored to two wall studs. Locate and mark the position of the wall studs to which you will fasten your sink by listening for a solid sound as you knock on the wall or by using a stud finder. If the studs in your bathroom do not line up to the mounting location for your sink, wood blocking can be installed between the studs using standard 2 x 4s.
   Step 2  
  Drill mounting holes for the anchor or lag bolts using the guides created in the previous step. If the wall is tile, use a masonry drill bit.  
   Step 3  
  Attach the new faucet and drain assembly to the sink.  
   Step 4  
  Secure the mounting plate to the wall with the anchor bolts. If there is no mounting plate, attach the sink directly to the wall with the mounting hardware.  
   Step 5  
  Connect the water supply and drain lines.

Note: Some wall-mount sinks include a trim piece to cover the plumbing lines. These typically attach directly to the wall framing with lag bolts.
   Step 6  
  When installation is complete, turn on the water supply to check for any leaking from the water supply lines or sink basin.
