"I've lived with interlocking tiles, a floor coating and porcelain tiles in my two garages. I replaced the interlocking tiles with porcelain because I found them impossible to keep clean. Grease, oil and dirt became easily trapped on my interlocking tiles and the only way to keep them clean looking was to remove and lay them out on the driveway, spray them with a degreaser and hose them down. But I still couldn’t remove the dirt and grime that was compacted in between all of the crevices of the tile surface without having to pressure wash each one individually. This quickly became an annoyance for me, but may not be an issue for some.
Porcelain tile still remains the most durable, easy to clean and stylish flooring options for the home. They will not stain, fade, or suffer water damage so they are superior to natural stone which is not impervious to staining. If you live in a colder climate you also not have to worry about freeze or thawing.
As for the concern that homeowners "drop too much stuff ... (and would be) constantly cracking and chipping tiles" that is a valid concern to raise to a retailer or installer if you have never lived with tile before. But you should know that the physical ability of porcelain tile to withstand breakage is significant once they are installed. If you lay a tile on a concrete floor and drop a hammer on it, it might break. But once tile is mortared to a concrete substrate they are not likely to break, making them rated among the toughest flooring materials.
There are the reasons why you find porcelain tiles suitable for areas where heavy traffic, abrasive dirt and moisture is a concern, such as building entrances, swimming pools, or retail centers (malls). It’s the same reason why manufacturers such as Ferrari, Lamborghini, and BMW, to name a few, have installed porcelain tiles on the floors to their manufacturing and repair facilities. I’ve inserted some pictures of these tiles in use.
A nice feature about porcelain tiles is that if you accidentally happen to catastrophically damage a tile (maybe you drop an engine block, for example), you can simply cut it out the damaged piece and replace it with a new one. Furthermore, if you happen to chip a tile that does not need replacing, porcelain tiles have the same color underneath.
Note that not all tiles are alike. Natural stone or ceramic tiles are different from porcelain and are not appropriate for the garage.
Porcelain tiles may be the most expensive of the flooring options discussed here, but properly installed and maintained, porcelain tile can last a lifetime."
