How to Put Backsplash Around Outlets

Installing a beautiful backsplash in your kitchen can add style and personality, but dealing with outlets in the backsplash area takes a little extra planning. With some simple preparation and the right materials, you can easily incorporate outlets into your new backsplash for a seamless look.

Prepare the Outlet Area

Before installing the backsplash, make sure to:

  • Turn off power to the outlet at the breaker box for safety.
  • Remove the outlet covers and disconnect the wires.
  • Detach the outlet from the electrical box it’s attached to.
  • Remove any old caulk or debris around the electrical box.
  • Ensure the box extends at least 1/8″ beyond the surface of the wall. This allows space for the backsplash tile to slide under the box.

Thorough preparation ensures the backsplash tiles will lie flat and the outlet will mount properly.

Waterproof the Outlet Box

Since the backsplash will expose the outlet box to splashes and moisture, it’s important to waterproof it:

  • Wrap the box in a product like self-adhesive waterproofing membrane.
  • Apply 100% silicone caulk around the edges.
  • Let it cure fully before installing backsplash tile.

This crucial step prevents moisture from reaching live electrical components.

Install the Backsplash

With the box prepped, you can install the backsplash tile:

  • Cut tiles to fit snugly around the outlet box.
  • Maintain a 1/8″ gap between tiles and the box.
  • Apply thinset mortar and press tiles into place.
  • Let thinset cure fully before continuing.

Be sure not to cover the box itself with mortar or tiles. The 1/8″ gap lets the outlet sit nicely flush with the new backsplash.

Insert the Outlet

Once tiles are set, dry, and grouted, finish the outlet installation:

  • Apply a bead of silicone caulk around the box edges.
  • Insert the outlet into the electrical box.
  • Attach the cover plate, checking for cracks around edges.
  • Allow silicone to fully cure before restoring power.

The caulk provides extra moisture protection behind the plate. Choose an outlet cover that complements your backsplash style.

Helpful Tips

  • Use a tile wet saw for easier outlet cutouts.
  • Select backsplash tiles 3-5mm thick to work well with outlets.
  • Replace old electrical boxes with extending outlet boxes for more room.
  • Choose outlet covers like brushed nickel that coordinate with backsplash tiles.
  • Have an electrician handle any wiring questions or complex outlet scenarios.

With attention to detail, you can install an outlet-friendly backsplash that’s both safe and beautiful.

FAQs About Backsplashes Around Outlets

How much space should I leave around the outlet box?

Leave a 1/8″ gap between the outlet box and backsplash tiles. This allows the outlet to sit flush with the backsplash.

What’s the best way to cut tile around outlets?

Use a wet saw to accurately cut outlet openings in backsplash tile. A properly sized opening ensures the tile sits neatly around the box.

Should I remove the outlet while installing the backsplash?

Yes, disconnect the outlet and detach it from the box while installing backsplash tile. This allows you to easily waterproof the box and slide tiles under it.

Can I still use the outlet while installing the backsplash?

No, turn off power to any outlets in the backsplash area at the breaker box. Live electrical components and water from thinset or grout can be hazardous.

How do I attach the outlet cover plate over the backsplash?

Caulk around the outlet box before reattaching the cover plate. This provides extra moisture protection. Secure the plate carefully to avoid cracking grout or tile.

What if my outlet box doesn’t extend past the wall surface?

Outlet boxes must extend at least 1/8″ to accommodate backsplash tiles. If yours is recessed, you’ll need to replace it with an extended/tile-ready electrical box.

Can I just caulk around the existing outlet instead?

No, caulk alone won’t provide adequate moisture protection. The box itself needs to be waterproofed with membrane and silicone for safety near backsplashes.


Installing backsplash tile around existing outlets is doable with careful prep and the right materials. Ensure the electrical box is detached, waterproofed, and extended to fit flush with new tile. With some tile cutting, proper grouting, caulking, and a coordinating outlet cover, you can have outlets blend seamlessly into your kitchen backsplash. Paying attention to safety and details will lead to success. For any complex electrical issues, always consult a professional electrician. With a little handiwork and creativity, you can achieve an outlet-inclusive backsplash design.
