When we moved in to our house, the fireplace had some cracked tile on the hearth. It has been on my list to redo the tile, so after Christmas we tackled the project! I'll start with the before and after picture in case you don't want to read all the way through the post.
Step 1...break up the old tile. Trigg got his safety glasses on and we got to work. Hammers and crowbars!
I also picked up some of this edging material that creates a boarder where the tile meets the fireplace. I couldn't find black at the big blue and orange stores, but I did find it at Hank's Specialties in Urbandale.
