Adding a room to the house, new sunroom, four season. Want a tile floor, but love the slate look. I went to a tile shop and picked out a slate foor (coper rust) multi-colored slate and a slate knock off porcelin tile. I love the look of slate but worried about the maintenance. Room will have heavy foot traffic, people and dogs, mud in winter/spring will be heavy with dogs. We get a discount if we use a certian tile shop so trying to find something at that store. Limits my shopping around a bit. Anyone have slate floors? Like/dislike the floors, upkeep hard?
