Can You Drill Into Backsplash? An Expert Guide

So you’ve decided to install a backsplash in your kitchen or bathroom. As you’re preparing for the project, you may be wondering – can you drill into a backsplash? The short answer is yes, you can drill into most backsplash materials. However, there are some important factors to consider before drilling to avoid damaging your new backsplash.

What is a Backsplash?

A backsplash is a protective surface installed on the wall behind a sink, stove, or other appliance to protect the wall from water damage and stains. Backsplashes are commonly made from ceramic tile, natural stone, glass, metal, and other materials. They add visual interest and character to kitchens and bathrooms.

Backsplashes serve both practical and aesthetic purposes. On a practical level, they prevent water from soaking into the drywall behind sinks and stoves. They also make these high-traffic areas much easier to clean. In terms of aesthetics, backsplashes provide an opportunity to showcase decorative, colorful, or textured materials as part of your design scheme.

Why Would You Need to Drill Into a Backsplash?

There are a few reasons you may need to drill into a newly installed backsplash:

  • To install mounting hardware for hanging utensils, pots and pans, paper towel holders, and other kitchen or bath accessories
  • To mount brackets or other hardware for shelves or floating cabinets above the backsplash
  • To install sconce lighting or other electrical fixtures directly into the backsplash tile or material
  • To mount a new soap or lotion dispenser into the backsplash in a bathroom
  • To install plumbing for a new faucet or fixture that will sit in front of the backsplash

Factors to Consider Before Drilling

Before pulling out the power drill, there are some important factors to keep in mind:

Backsplash Material

What is your backsplash made of? Natural stone, ceramic tile, glass tiles, and metal backsplashes will require different drill bits and techniques. Porcelain or ceramic tiles are very hard and brittle and require diamond-tipped drill bits. Glass tiles can easily crack or shatter when drilled into and require special care. Know your backsplash material before drilling.

Use Proper Tools

Having the right drill and drill bits is key to avoiding cracks and chips in your backsplash. As noted above, ceramic and porcelain tiles require diamond-tipped drill bits. Using the wrong drill bit can result in damage. Match your tools to the material.

Protect Surrounding Areas

Take precautions to protect the surrounding countertops, walls, and floors from drilling debris. Lay down drop cloths and mask off adjacent surfaces. Use painter’s tape around your drill hole location to prevent cracks from spreading.

Check for Electrical, Plumbing, or HVAC

Always check for wiring, pipes, or vents behind the drill location before starting. Use a stud finder or inspect any available building plans to avoid puncturing any unseen electrical, plumbing, or HVAC systems. This could cause a much larger repair job.

Go Slowly and Use Low Speed

When ready to drill, start slowly at a low speed. High torque or speed can cause cracking around the drill hole, especially in brittle materials like ceramic and glass tiles. Let the drill do the work. Apply light, even pressure.

Use Water Lubrication

For ceramic or porcelain tile, keep a spray bottle of water handy. Spritzing water as you drill helps lubricate the tile and keeps the drill bit cool.

By taking these precautions and using proper technique, you can safely drill into most backsplash materials without causing cracks or damage. Always test on a spare tile first before drilling directly into a finished backsplash. With care and patience, you can mount hardware, fixtures, and accessories to customize your backsplash design.

How to Drill Into Common Backsplash Materials

Here are some best practices for drilling safely into specific backsplash tiles and materials:

Ceramic or Porcelain Tile

  • Use a carbide or diamond-tipped masonry drill bit
  • Apply painter’s tape around drill area
  • Drill at slow speeds of 400-600 RPM
  • Lubricate by spraying water as you drill
  • Start with light pressure to create a guide hole before drilling fully

Natural Stone Tile

  • Use a diamond-tipped core drill bit for stone
  • Go slow and lubricate while drilling
  • Soak area before drilling to soften stone

Glass Tile

  • Purchase special glass and tile drill bits
  • Apply duct tape to the area to help prevent cracks
  • Drill at slow speeds and with light pressure
  • Soak the tile before drilling

Metal Backsplashes

  • Use a high-speed steel twist drill bit
  • Clamp the metal in place to prevent vibration
  • Apply machine oil as lubricant when drilling
  • Allow time for the drill to cut the metal; don’t force it

Tips for Drilling Holes in Backsplash Tile

Follow these tips for clean, safe drill holes every time:

  • If drilling through an outlet opening, use an edge guide for precision
  • Place a piece of plywood behind the tile to prevent chip-out
  • Start with a pilot hole before using larger drill bits
  • Grind smooth any rough edges around the drill hole
  • Clean surface thoroughly after drilling to remove debris
  • Consider using a special diamond hole saw for a cleaner opening

Taking it slowly and using the right tools will result in successful drilling with minimal damage to your backsplash. Be sure to follow any specific instructions from the backsplash manufacturer as well. With some careful preparation, you can mount accessories and fixtures directly into your backsplash tile or material.

FAQs About Drilling Into Backsplash

Can you drill into ceramic tile backsplash?

Yes, you can drill into a ceramic tile backsplash. Use a diamond-tipped masonry drill bit, apply painter’s tape around the drill area, keep water lubrication on the tile, and drill slowly at 400-600 RPM. Go easy on the pressure.

What kind of drill bit do you use for backsplash?

The drill bit type depends on the backsplash material:

  • Ceramic or porcelain tile – Diamond-tipped masonry/tile drill bit
  • Natural stone – Diamond-tipped core bit for stone
  • Glass tile – Specialty glass and tile drill bit
  • Metal – High-speed steel twist drill bit

How do you drill into a stone backsplash?

For a natural stone backsplash, use a diamond-core bit made specifically for stone drilling. Drill at a low speed, lubricate with water, and apply minimal pressure. Soaking the stone area beforehand makes drilling easier.

What should you not drill into?

Avoid drilling into areas with electrical wiring, plumbing lines, or HVAC ductwork hidden behind the wall. Also do not drill into asbestos tile. Identify what is behind the drill area before starting.

Can you mount things on backsplash tile?

Yes, backsplash tile and materials are great for mounting hardware, lighting fixtures, floating shelves, and accessories. Just be sure to use the proper drill bits and techniques for that material to avoid cracking or shattering the tile.


Drilling into a kitchen or bathroom backsplash is certainly possible for most materials with the right approach. Always identify your backsplash type, use the appropriate drill and bits, and take precautions to protect surrounding areas from damage. Employ slow speeds, light pressure, and water lubrication when drilling to get clean, stable holes for mounting hardware and accessories on your decorative new backsplash. With care and patience, you can customize your backsplash design by drilling safely and effectively.
