Setting up the R.W.FLAME 36 inch electric fireplace, especially if you want that recessed look, can require some time and effort, but it's definitely manageable with a bit of preparation. The manufacturer suggests the possibility of a recessed installation, but the tricky part is that it doesn't come with side mounting brackets for this.
If you're going for a flush, built-in appearance, you'll probably need to build a frame to hold it securely in the wall.
Based on our research, a lot of folks have successfully installed it by creating custom frames that fit its dimensions: 3.86"D x 36"W x 18.11"H. You'll need to make sure the space can accommodate the unit snugly. Some people have mentioned adding a rear brace for extra stability, which seems to be a handy tip if you prefer a more secure setup.
As for the power, make sure there's an outlet within the recess, or have a plan to wire electricity to the fireplace afterward. If you have an old, non-working fireplace, that can be a good spot to install this unit—as long as the dimensions work. Minor modifications might be needed, but with its slim profile, the R.W.FLAME fireplace is pretty adaptable.
Also, while it can be recessed, this fireplace design leans more towards wall-mounting, and folks often find this the easier route. It's usually straightforward and looks great without needing more hardware.
So, if you're keen on a recessed installation, just keep in mind it involves extra steps and materials, but it's totally doable. Planning ahead and setting up the right supports will go a long way to achieving a secure and good-looking result.
But, if DIY isn't your thing, maybe consider the simpler wall-mount option.
