Stone veneers are often used for siding, but also make great fireplace veneers. When choosing your stone for the fireplace veneer, consider how much space there is to cover. Fireplace veneer style options are snap-on fireplace box shapes for a quick upgrade, veneer on the wall above the fireplace, or veneer on the entire wall. Also consider that a larger stone will not likely be aesthetically pleasing on the whole wall, while a small stone might appear understated. Always shop around for the best deal, and look for timeless stones that will work with any future changes in the space.
Brick veneer will create the appearance of real brick without the time and work required to install a real brick wall. Installing a brick veneer is still messy, however, so someone with previous tile or masonry experience should take on the job. Brick veneers are a lot like bathroom wall ceramic tiles: both are only half-inch thick and can be set in mortar. Another option for installing brick veneers is to use metal tracks, which are installed horizontally on the fireplace wall; the individual veneer brick pieces then snap into place. This is a faster, less messy approach.
Wood is often incorporated into stone veneers or brick veneers to create a harmonious effect for cosmetic purposes--especially if the room's existing decor already incorporates wood into the design. There are strictly wood veneer options, but most people tend to opt for the stone/brick-and-wood combination because of durability and attractiveness.
