However, the designs on these doors are almost alike in such a way that they can all be described as "simple and elegant." And although these new simplistic designs would probably look good on modern fireplace designs, these may be incompatible with the rustic brick fireplaces. A masonry fireplace door would probably look better with a frame made to look like antique brass.
