Hi Christy, How large is the opening? Do you mean a gap from the back of the stove to the backsplash area? Or do you mean you have an oven without a wall behind it.
If it is the first case, maybe you could build out the backsplash, so there is less of a gap.
Christy: you could build a small pony wall
here is some info: make sure it is heat proof
I agree with the idea of a small pony wall. Maybe you could also build a shelf instead of a wall for extra storage?
Add a covering the same height as the stove leaving room for either the gas pipe or the electrical plug. Not sure what your set up looks like without picture. Build a frame out of 2x4's and attach to the flooring. Cover with beadboard, or wood.
Hi! There was a gap between my stove and backsplash. I put a shelf there, which is easily removed if needed. Good luck and stay safe!
Could you use a decorative Fire Guard? or a screen, or maybe a piece of suitable furniture suitably placed.
Build a half wall. It could be very simple as 2x4s with plywood or drywall.
You can place a shelf there - something metal perhaps.
You could put a piece of wood.or sheetrock as long as it is not on the stove it self.
If it's something like what's shown in the picture in this post, they suggested a piece of granite or countertop. They also suggested swapping the stove out for a slide in...which is of course a big expense. https://www.houzz.com/discussions/3040464/need-an-idea-for-back-of-stove
A sheet of metal works, you can even paint it.
You can attach a metal panel to it. Small machine screws.
Could you send a picture? What view needs to be hidden? Top, back, sides?
This is a cooking stove, yes?
What kind of opening is it? Like the turn of a counter and the stove is seen? There should be a panel on the other side that matches the cabinetry.
