I’m absolutely in love with our new DIY fireplace! It honestly turned our better than I expected, and this thing is huge! We used the 48” Dimplex Sierra Linear Electric Fireplace. It puts out great heat and has a bunch of cool features, like multiple different color flame options, heat levels, and insert choices.
