HGTV has a page devoted to fireplaces and mantels on its website. It features videos on how to select a mantel design and several galleries of mantel design ideas. Companies that sell fireplaces, such as Solus Decor, also often feature design galleries; the Solus Decor gallery features contemporary concrete mantels.
Both traditional and contemporary mantel designs are featured on the HGTV website. Clicking Read More under each photo in the gallery displays whether or not the curators have tagged a design as contemporary. Other information, such as decor ideas to match particular mantels, can be found in this section as well.
