I need help modernizing a desert home fireplace. We removed the base columns and kept the hearth and mantel for now. Flat screen TV to come, centered over mantel. My hubby wants stacked stone on back wall but it's VERY expensive to do the whole thing. We have refinished cabinets in espresso across the room and I'd like to have a bit of those tones here but don't want the fireplace to overpower the room. We are advised NOT to use wood in the mantel or surrounds because of extreme temps in the summer. Any suggestions?
