Hi! We're giving our fireplace a complete makeover, and would like to install a mantle like the one seen in this photo. It's white with traditional details on the lower mantle with a natural wood shelf above. I haven't seen anyplace that sells a complete mantle like this. Have you? Do I need to buy the lower and upper parts separately? If so, any idea as to where I might source just the lower mantle? A reclaimed wood mantle shelf should be easy enough to find. Thank you!
