My floor is porcelain tile. EZ clean-up & durable if tile installed with no voids (back buttered) I’ve dropped wrenches, hammers, even a TH400 trans when it fell off the trans stand. No damage at all. Grey grout doesn’t show much & tile is varigated & hides lots of spillsA friend built a new garage to keep his cars in a few years ago and invited some folks over to see it. Frankly all the clean floors and walls makes me real uncomfortable. The floor is ceramic tile. I asked him how you jack a car up on ceramic tile, he said he never has.
