This fireplace is huge! It’s very solid and heavy, well made. The mantle looks built in. It took me about an hour to put it all together alone with “help” from my toddler twins. I needed a flat head screw driver for some locking screws at the beginning, and a philips screw driver and a drill to make pilot holes for hanging the actual fireplace at the end. The rest was done with a provided Allen wrench. It was all very easy to put together. Directions are photos that are kind of small, but it’s pretty simple to follow. The hardest part was getting the giant box in the front door after delivery. The heat is fairly quiet and hot. The electric fireplace part is very nice. Highly recommend! This one is a thousand times nicer than the first electric fireplace I tried last year. Let’s hope it holds up to family life! )
