Not all tile is made equal. Some tile material is better suited for high-traffic areas. If you are planning on tiling a hallway, entrance-way, living room, or other high-traffic area, make sure you use Group V tile. Tile flooring is rated and characterized into groups; Group I - Group V. Group I tile is best suited for countertops, while Group V tile can endure heavy traffic and can be used almost anywhere.
If you're tiling an area of your house that will see a lot of water (read: bathroom, kitchen, etc), you want to make sure you're using a tile that is rated as "impervious", "non-absorbent", and "non-porous". If you opt for a more porous tile in a bathroom or kitchen area you may be setting yourself up for some expensive repairs or replacement projects down the road.
Not all tiles work best for artistic interior design projects. A creme porcelain tile might be just fine for a bathroom counter, but it might be a bit dull for an entranceway. Try livening up your tile flooring design with a textured or multicolor porcelian, or a patterned glass mosaic tile.
This glass mosaic tile would look stunning as a decorative entranceway or runner.
