Install & Replace


Spacer board behind over-the-range microwave

Hi.  I'm purchasing an OTR microwave that is slightly taller than the microwave being replaced.  There is a tiled backsplash that goes up higher than the bottom of the new microwave.


I was going to install a 30x15x1/2" wood board to the studs that I can then attach the microwave's mounting plate to so I can avoid having to try to cut the backsplash. 

Is there a particular type of wood I should be getting that will be able to adequately support the microwave?  It's an LG that weighs ~60lbs.

Hi rk260395, this is Mike The Home Depot Answer Man, welcome to the community.


I would recommend a piece of exterior grade plywood. Exterior grade plywood has a glue that is weather proof. This will prevent cooking steam from causing the wood to delaminate.


I would also recommend you stain or paint the portion of the wood that is exposed to match the rest of your cabinetry.


Be sure to securely attach the wood to the studs with screws. I would use at least 1 ½ or 2 inch screws. Place at least two screws into each stud to make sure the wood is secure.


If possible to maximize the strength of the mounting, try to place the mounting bracket so the screws on it penetrate the studs as well.


Good luck with your project.

Thanks a lot.  And I do plan on screwing in the back board to the stud as well as the mounting bracket.  Not exactly relishing the thought of a 60lb microwave crashing down on a ceramic stove top.  :)
