Measure the available wall space to decide where to place the new faux fireplace. Write down the measurements on a sheet of paper. Use the pencil to draw markings on the wall's area that will be designated for the faux fireplace.
Find a mantel that fits the recorded measurements. An old vintage mantel can be found at a salvage yard or a new and stylish fireplace mantel may be purchased at a home improvement store.
Place a piece of precut fiberboard on the floor where the faux fireplace will be set. This board will become the new faux fireplace's hearth.
Arrange tiles of your choice on fiberboard and then fill in the lines between the tiles with a tile sealant.
Purchase a mirror that is a few inches larger in width and length then the opening of the mantel. This will ensure that the mirror will remain secure behind the mantel. Set the mirror against the wall and onto the middle of the fireplace hearth.
Place the mantel in front of the mirror. Drill a 3-inch wood screw through both the left and right top corners of the mantel and into the wall studs.
Stand a fireplace safety gate or screen in front of the hearth and then place candles on the tiles of the hearth to create a soft and flickering glow. Place decorative stones or rocks around the candles to help keep them in place and catch any wax drippings.
