No assembly required, other than putting the propane tank inside! Always a plus. Also, no ugly hose and side box housing the propane tank. The shipping left a lot to be desired as the unit was sent upside down (with the weight on the top) and the box was severely damaged making me quite nervous to even open it. Once I did open it, it seemed to have survived the terrible packaging. I did place two large tiles on rubber foot mounts to cover the top when not it use. I also opted for some blue fire glass over the ugly fire rocks that come with it. Takes some time to get the propane through the tubing so don't think it isn't working when you first turn it on. Works great. Not a ton of heat on low but fantastic ambience.
