Took two of us two hours and 45 minutes to put together. The only tools we needed that weren't included were a Phillips Screwdriver & a hammer. We are not handy people but instructions were easy to follow. My tv is 40 inches (for scale). 

The heater/fireplace instructions tell you unplug when you're not using it. I used a switch activated outlet instead. It's nice that you can turn on the fireplace with or without the heater. and the heater can be used with or without the fireplace. I am super satisfied with my purchase.
