Seeking opinions: Seems that I've seen this a few times now, people staining their basement concrete floors and giving it a "faux" finish, like one often sees in the exterior with stamped concrete patios. I had one in a luxury home a while back where the owners had the builder use a diamond saw to cut the surface of the slab into squares to make it look like large tiles and then applying a stain to the surface. While there are some quality considerations and the concrete treatments vary in cost and appeal, it seems proper to me to call it a finished floor (with caveats). Does this seem reasonable? The motivation to do this would seem only to be a cost savings over tile or wood, or other method to finish the floor yet not have carpet, which some do not want, especially when one has pets.
