Just moved and before we repaint we we feel this fireplace (working) looks odd with no surround, mantel etc. Due to the raised brick ledge at the entrance I am thinking a traditional fireplace insert won’t work as it won’t be able to slide in due to the ledge. The hearth is also slightly wonky and the tiles are wider to the left than to the right. Wondering if just a surround fixed to the wall would look ok?
