How do you drill faucet holes or drain holes?

A step-by-step guide to drilling a faucet/bathtub filler hole:

Tools Needed:

  1. Pencil (not pen)
  2. Tape measure
  3. Rafter Square
  4. Drill
  5. 1/4" Hole Saw Arbor
  6. Diamond Grit Hole Saw
  7. Industrial Grade Acetone
  8. Clean Rag
  9. Disposable gloves (use at all times)
  10. Chemical Respirator Mask and Appropriate Eye Protection (use at all times)

Let's Begin:

  1. Using the pencil and tape measure, mark the spot where you would like to drill the faucet hole/s. Typically, the spots for a sink should be marked in the center (left to right, front to back) of the faucet deck directly behind the sink bowl. If your desired faucet has separate handles (left and/or right) mark those as well. The distance between hole to hole varies depending on preference and/or the make and model of the faucet/bathtub filler chosen.
  2. Check underneath the fixture to make sure that each marked spot on the opposite side does not interfere with the structure or functionality of the fixture when drilled. Take into account the diameter of the diamond grit hole saw that will soon be used. Common drilling mistakes include but are not limited to: drilling into the material thickness of the fixtures construction, not calculating additional surface area underneath or on the opposite side for the faucet hole cover plate or fastening nut/s, drilling a hole in an area that will interfere with a wall mounted bracket or lag bolt location, etc.
  3. Using light to moderate force, drill a pilot hole in each marked spot from the top (visibly installed side) using the 1/4" hole saw arbor while the fixture is on a leveled surface and the drill is perpendicularly aligned with the faucet/tub filler deck. After each pilot hole is drilled, place the 1/4" hole saw arbor into the pilot hole and drill (again with light to moderate force) the faucet/bathtub filler hole using a diamond grit hole saw with the dimension desired or needed for your chosen faucet/bathtub filler. Typical dimensions used are 1", 1-1/4", 1-3/8" and 1-1/2". It is best to check the faucet/bathtub filler specification sheet and/or the manufacturer of the chosen faucet/bathtub filler to confirm.
  4. Lastly, discard of the drilled out material along with any residue from the drilling. For any pencil markings left, apply a small amount of industrial grade acetone to a clean rag and clean the surface. If for any reason you still have markings that need to be removed, contact our staff for specific instructions. Instructions may vary depending on the model, finish, marking type, etc. Be sure to always use the appropriate eye, respiratory, and hand protection.


What is our Stone Resin Solid Surface material?

Our Solid Surface Stone Resin is a compact, high-quality surface material. The composition is durable, soft to the touch, and easily repaired. Majority of our applications involve the matte finish due to its rich feel and easy care & maintenance.

What makes ADM’s products unique?

  • Natural insulator and warmer to the touch.
  • High stain resistance.
  • The option of choosing between Matte and Glossy White as the finish for all our designs (some color options available).
  • Solid casting and hand sanding ensure the utmost precision, quality control, and care.
  • Drillable material opens the option for a deck mounted tub filler.
  • The material can be painted and polished if desired.
  • Integrated overflows hide the unnecessarily visible plumbing.
  • Easy to clean with soapy water and sponge; for stubborn scratches and dirt, use fine sandpaper to buff out and make like-new (matte only).
