Installing a tile backsplash can add a beautiful, durable, and easy-to-clean accent wall to your kitchen. However, you may run into the issue of what to do with existing outlets that are located in the backsplash area. There are a few options for dealing with outlets when tiling a backsplash to make sure they remain functional and accessible.
Turn off Power and Remove Outlet Cover
The first step is to turn off the power to the outlet at the breaker box. Make sure to test that the power is off with a voltage tester before proceeding. Then, use a screwdriver to remove the outlet cover and expose the wiring.
Extend the Outlet Box
If there is not enough clearance between the existing outlet box and the planned tile installation, you will need to extend the outlet box so it sits flush with the finished tile surface. This can be done by removing the screws holding the box to the wall, inserting a box extender between the existing box and wall framing, then reattaching the box. Make sure any box extenders used are listed for use in tile backsplash installations.
Waterproof the Box
Since the outlet box will now sit behind the tile, it’s important to waterproof it to prevent moisture damage. Apply a bead of silicone caulk around the edge of the box where it meets the wall. Pay special attention to the top and bottom edges. Then, cover the inside of the box with a painters plastic bag secured with electrical tape before reinstalling the outlet and cover plate.
Option 1: Install Tile Around the Outlet
The easiest option is to simply tile around the outlet, leaving its original position untouched. Make sure to turn off power before wiring the outlet back up. With this method, the outlet cover plate will sit on top of the tile. Pay attention to the thickness of the tiles – the outlet box needs to be deep enough that the cover plate can sit flush to the tile without stressing connections.
Option 2: Move the Outlet to Accommodate Tile Layout
If needed, you can move the outlet box to better accommodate the tile layout. Turn off power and disconnect the outlet. Cut the drywall around the box, and make note of the wiring connections. Remove the box, then patch and seal the old hole. Cut a new opening at the desired location, fish the wiring over, and install a new outlet box secured tightly to the wall framing. Wire up the connections, waterproof the new box, and finish tiling.
Option 3: Install Outlet Outside the Backsplash Area
For a seamless tile application without any outlets disrupting the pattern, consider moving the outlet completely outside of the backsplash area. Shut off power and disconnect the outlet. Cap the wires inside the box, patch and seal the hole in the wall, then tile over it. Install a new outlet box at a location above or below the backsplash and run new wiring to it from the breaker panel. Make sure to get permits and have rough-in electrical work inspected as required by code.
Protect Outlets During Installation
When setting the tile, take care to prevent any grout or adhesive from getting into the outlet box. Use painter’s tape to cover exposed outlets during the installation process. Make sure the outlets remain covered until the grout has cured, and avoid getting any water or moisture into the boxes while cleaning tile during and after application.
Use Waterproof Backer Board Around Outlets
Install an appropriate waterproof backer board, such as cement board or densshield, wherever tile will surround outlets. This provides an extra layer of moisture protection behind and around outlet boxes. Make sure the backer board is properly taped and sealed according to manufacturer instructions.
Tiling around existing outlets is entirely doable with some careful planning and attention to detail. Always exercise safety and turn off the power when working on electrical. Extending the boxes, waterproofing, and taking precautions during install will help ensure your outlets function properly for years after your new backsplash is installed.
Frequently Asked Questions About Outlets and Tiling Backsplash
Can I tile directly over an existing outlet?
No, it is not safe to tile directly over an outlet box. The outlet must be accessible and properly protected from moisture. Extend the outlet box so it will sit flush behind the tile surface.
What is the best way to waterproof an outlet behind a tiled backsplash?
Cover the inside of the outlet box with plastic sheeting or a plastic bag secured with electrical tape. Apply silicone caulk around the edges where the box meets the wall. Keep outlets covered while tiling to prevent water damage.
How close can an outlet be to a backsplash?
The National Electrical Code requires outlets within 6 feet of a sink to be GFCI protected. Outlets can be placed 4-6 inches above the counter, just under where the backsplash will end. Always check local codes for exact requirements.
Should I turn off power at the breaker before removing an outlet?
Yes, you should always turn off the circuit breaker for an outlet before doing any work on it. Test that power is off with a voltage tester for safety.
Can I adjust the position of an outlet when tiling a backsplash?
Yes, you can remove an outlet and relocate it higher, lower, or off to one side during a backsplash installation if needed to better accommodate the tile layout. Be sure to turn off power and cap all unused wires appropriately.
What precautions should I take when tiling around outlets?
Use painter’s tape to cover exposed outlet boxes during install. Carefully tile up to the edges of the box without getting any thinset or grout inside. Keep outlets protected until grout is fully cured before removing tape.
Conclusion
Installing a tile backsplash provides a great opportunity to update the look of a kitchen. With proper planning and electrical safety precautions, outlets can be adapted to work with new tile layouts. Extending boxes, waterproofing, and extra care during the installation process allows outlets to coexist with a tiled backsplash while retaining full functionality. Attention to detail ensures a beautiful finished product that also meets code requirements. With some clever adjustments, outlets and backsplashes can be combined in your kitchen renovation.
