I'll be framing out some walls on a tile floor laid over a concrete slab subfloor. As I understand it, the proper way to do this is to cut out the top flooring, and attach the walls' base plates directly to the subfloor, in this case the slab.
The tile floor is in fine shape, so what I'd like to do is use an angle grinder or circular saw to cut out channels through the tile for the walls. Will this work? If I cut a line down a tile and it cracks, the finished product will not look good, because I'll have to replace the broken tile with whatever I can find that looks similar.
