Step 1: Prep for Faucet Installation

Determine the height at which the faucet will be mounted to the wall. In our project, we used a faucet with a showerhead.

Put a plywood backer in place in the adjacent room or access space so the faucet attaches to something sturdy.

Step 2: Drill Holes in Wall

Drill a pilot hole from the access wall in the adjacent room (Image 1).

Get as close to the stud as you can while allowing space for the plumbing. Drill through the wall from the adjoining room. In our project, the first drill into cultured marble was for the hot water side of the faucet (Image 2).

Measure the distance between the hot and cold on the faucet (Image 3) and transfer that measurement to the wall.

Use a torpedo level to make sure the holes are even (Image 4).

Drill another pilot hole for the other side of the faucet through the bathroom wall. Tip: use a stop collar on the drill to keep it from going too deep and hitting the plumbing (Image 5).

Use a hole saw to cut through marble or other dense material (Image 6).

Step 3: Install the Faucet

Slide the faucet into place (Image 1) and tighten the bolts on the back of the faucet in the adjacent room or access space (Image 2).
