    Could you get rid of the floor box and use a different material to cover the gap? Maybe a complimentary stone or brick?

    What sort of look so you like for your room. Here’s how we made a mantle for our faux fireplace: https://www.frugalfamilytimes.com/2019/05/how-to-build-faux-fireplace-in-corner.html?m=1

    Linda: if you don't use the fireplace and it's only a focal point, you could get rid of box and simply replace it with a nice wool rug!

  • I realize you don't like the box below your fireplace but there are building codes that require you to have a hearth below your fireplace to catch burning embers.

    • For fireplace openings 6 square feet or smaller, the hearth should extend out a minimum of 16 inches, and 8 inches on the side.
    • Larger fireplace openings need a minimum extension of 20 inches plus 12 inches on the sides.

    There is no height restrictions for a fireplace hearth so you can remove the box you dislike and replace it with some type of noncombustible material like slate or tile. I'd probably go with something that's the same color as the surrounding flooring so you barely notice the change in flooring. HOWEVER, you must be very careful that there's enough support under the new flooring so it doesn't crack. When I owned my handyman business, this was a common repair when the sub-floor was uneven.


    For the mantel you're not thrilled with, I agree it doesn't add much to the fireplace. The easiest way to deal with it short-term would be to paint it a color close to that of the stone so it simply blends and fades into the background. That way the stone you love will get all the attention.


    I've got lots of fireplace articles on my website in case you've got more questions.
