What is an Outlet Extender?
An outlet extender, also called an outlet spacer, is a simple device that extends your electrical outlet forward so that it is flush with the front of your new backsplash. It is a plastic or metal box that the outlet screws into, with space in the back for the extra tile depth. This allows you to safely use your electrical outlets even with a backsplash installed.
When Do You Need an Outlet Extender?
There are a few scenarios when you will definitely need an outlet extender for your new backsplash:
Backsplash Depth Exceeds Outlet Box Depth
Standard outlet boxes are 1/2 inch deep. If your backsplash tiles are thicker than 1/2 inch, your outlets will be recessed behind the tile. Outlet extenders compensate for the extra depth.
Backsplash Covers Existing Outlet
If you are installing a full wall backsplash, such as subway tile from countertop to ceiling, it will cover your existing outlets. Extenders bring the outlets flush with the new tile.
Backsplash Prevents Plugs from Fitting
Even if your outlet box is deep enough, a protruding backsplash can prevent plugs from fitting into the outlet properly. Extenders fix this by moving the outlet forward.
Adding an Outlet in the Backsplash Area
If you are adding a new outlet near or behind where the backsplash will be installed, use an extender so the new outlet will be flush with the tile.
When Can You Get Away Without an Extender?
If your backsplash tiles are very thin, such as metal or glass mosaics under 1/4 inch, you may be able to get away without an outlet extender. The outlets might not end up perfectly flush with the tile but should still be functional.
You also might be able to skip extenders if you are keeping backsplash only in certain areas and not covering outlets. For example, a small backsplash focal area behind the stove may not impact your outlets.
However, using outlet extenders is still the best practice anytime you are installing backsplash near electrical outlets. It ensures your outlets remain accessible and up to code. The extenders are simple to install along with the backsplash.
How to Install an Outlet Extender
Installing an outlet extender is a quick DIY project:
Turn Off Power
Turn off power to the outlet at the breaker before beginning. Double check it is off.
Remove Cover Plate
Take off the outlet cover plate so you can access the side screws.
Detach and Unscrew Outlet
Carefully detach the outlet from the wall and unscrew it. Pay attention to where the hot and neutral wires are.
Mount Extender Box
Screw the extender box into the existing electrical box using the provided screws.
Reattach Outlet
Attach the outlet to the front of the extender using the side screws, maintaining correct hot/neutral wire positioning.
Install Tiles
Install backsplash tiles over the extender box as normal.
Replace Cover Plate
Once tiles are set, replace the outlet cover plate, turn power back on, and enjoy!
Using spacers is the best way to make sure your outlets remain functional after installing a backsplash. It just takes a few extra minutes per outlet.
Frequently Asked Questions about Outlet Extenders
Do outlet extenders reduce safety?
No – as long as they are installed correctly according to the manufacturer’s instructions, outlet extenders do not reduce electrical safety at all. They simply move the outlet forward to accommodate backsplash depth.
Can I put the extender on before the backsplash?
Yes, you can install the outlet extender boxes before setting your backsplash tile. This allows you to make sure spacing is correct before tiling around the boxes.
How much do outlet extenders cost?
Basic plastic outlet extenders cost around $2-$5 per box at hardware stores. Higher quality metal extenders cost up to $15.
Should GFCI outlets be extended for backsplash?
Yes, any outlets covered by backsplash should be extended, including GFCI outlets. Make sure to match GFCI extenders with GFCI outlets.
Do I need an electrician to install extenders?
While always recommended for electrical work, outlet extenders can be safely DIY installed by homeowners comfortable working with household wiring. Follow instructions carefully.
How deep should the extender box be?
Choose an extender depth that matches or slightly exceeds the tile thickness. Common depths are 3/8″, 1/2″, 5/8″, and 3/4″ to accommodate various backsplash tiles.
Conclusion
Installing backsplash tile can make your kitchen look amazing, but you don’t want to lose outlet function. Using simple and inexpensive outlet extenders is an easy solution to keep your outlets flush and usable. Consider adding extenders anytime outlets will be covered or tight space behind backsplash could make plugs difficult to insert. With a few extra minutes per outlet during your project, you can avoid accessibility and safety issues down the road.
