Step 1: Measure and Drill Cabinet

In order to put the cabinets in place you need to drill holes — two for the supply lines and one for the drain. Use a hole saw because the diameter is slightly larger than the supply line.

Take measurements and make sure once the cabinet is flush against the wall the door won't be hitting a window sill or frame, etc. If you need to put the cabinet an inch from the wall, you can use fill stock to cover it.

Step 2: Cut Cabinets and Fit the Pipes

Remove the cabinet doors for easier access.

Start cutting from the outside of the cabinet and then finish cutting from the inside; that way if it splinters, the rough cut will be against the wall and no one will see it (Image 3).

After the holes have been cut, fit the cabinet over the pipes (Image 2).

Step 3: Clamp Cabinets Together

Once all the cabinets are in place, clamp them together at the face frame. Pre-drill pilot holes and then screw the cabinets together.
Note: Use the screws that are provided with the cabinet.

Step 4: Attach Cabinets to the Wall

Check the level before you screw the cabinets to the wall.

If needed, a few shims under the toe kick will get the cabinets right where you need them — perfectly level.

Screw the cabinets into the studs using three-inch cabinet screws.

Use fill stock to take up the gap between the cabinet and the wall.
