Step 1 : Remove the old cabinet
Remove the door from the cabinet and find the fasteners that hold the cabinet in the wall cavity. Then remove them and pull out the old cabinet.
Step 2 : Remove the door and test fit the cabinet
If the new cabinet came with the door attached, remove it following the instructions from the manufacturer. Carefully store the door so it's protected to prevent damage to the mirror. Then test fit the cabinet body in the wall cavity. The cabinet should be square. Make adjustments to the cavity with shims if necessary. Remove the cabinet from the cavity.
Step 3 : Assemble the cabinet
Follow the manufacturer's instructions to assemble the cabinet frame.
Step 4 : Insert the cabinet frame in the wall opening
Carefully lift the body and frame assembly and insert it into the rough wall opening. Check again that it is level and square.
Insert the mounting screw assemblies in the mounting holes in the cabinet body following the manufacturer's instructions. If there are screw covers, snap them in place.
Step 5 : Install the door on the cabinet body
Install the hinge mechanism for the door on the cabinet body and position the door so it is properly aligned.
Step 6 : Install the shelves and check the door for alignment
Position the shelf brackets where appropriate for items and set the shelves on top of the brackets. Then check the door for proper alignment and make any adjustments.
