can you tile an old brick fireplacegt;?would it look stupid?
Are you still planning on using the fireplace? You will need to check with the manufacturer of the tile that it can withstand the heat. If you're tiling the exterior of the fireplace, make sure you select a corner bead for the exposed edge where the fireplace opening meets the wall plane. Installing tile over a fireplace is not a big deal if you're putting it on the wall plane. Whether it looks stupid or not depends on the type of tile you use and the overall color scheme. It could definitely work.
To do that it is a bit more complicated than it sounds. You would need to make the brick surface smooth, no crevaces. It's expensive time consuming. Consider resurfacing the fireplace
