Your Floor: How to Shop for Tile
Here's how to read a ceramic tile box and get exactly what you need
There's a lot more to buying ceramic tile than finding a color and pattern that will work in a room. Every tile manufactured and sold has an intended use, and that intended use is made pretty clear on the label of a box of tile. However, it's always in code. Understanding this code will go a long way to helping you buy the ceramic tile that's right for your project, and it may even save you money.
Grade. The first category is a tile's grade. A tile will have a grade from one to three. Grade one is the highest quality, grade two is similar to grade one but it will almost always be less expensive. Grades one and two are suitable for floors. Grade three tile aren't heavy-duty enough to walk on, and they're only intended to be used on walls. Though you can use floor tile as wall tile, you cannot use wall tile as floor tile. Be sure that any tile you're considering for your floors is at least a grade two.
Wear rating. The second category is something called a PEI rating. PEI stands for the Porcelain and Enamel Institute’s wear rating. PEI rates a glazed tile’s ability to resist abrasion and its suitability as a floor tile. Only glazed tiles get a a PEI rating, if you’re buying unglazed tile you won’t find this category on the the label.

Ceramic tiles rated PEI I and II are appropriate for use as wall tile only. They tend to be decorative and cannot withstand foot traffic. Tiles rated PEI III offer moderate resistance to wear and they are appropriate for most residential uses. Tiles that carry a PEI IV are highly resistant to wear and appropriate for all residential and some light commercial uses. Tile rated PEI V are the most resistant and are appropriate for use in heavy commercial locations. If you can save money with a PEI III or PEI IV tile, go for it. Anything rated higher than that is overkill for residential uses.

Water-absorption rate. Another important category to consider when you’re looking at ceramic tile is its water absorption rate or W.A. A tile’s W.A. rating will tell you if a tile you’re considering is the right tile to use in a wet area or outdoors.
There are four categories in the W.A. rating and they’re expressed as a name and percentage of water absorbed by a tile.

Nonvitreous tile absorbs more than 7% of its weight in water and is inappropriate for use outdoors or in a wet area such as a bath or spa. Semiviteous tile absorbs between 3% and 7% of its weight in water and it too is only appropriate for use in dry, indoor areas. Vitreous tile absorbs only 0.5% to 3% of its weight in water and it's a rating you want to see if you're using a tile outdoors or in an area where there's a lot of moisture present. The last category is impervious and it absorbs less than 0.5% of its weight in water when exposed.

What's called a porcelain tile isn't really made from porcelain, but it is in that final category, impervious. A tile has to absorb less than 0.5% in order to be called porcelain. A lot of times, that label porcelain carries a price premium and if you can save some money by buying a vitreous tile (0.5% to 3% water absorption) you'll be being a smart consumer. Tile categorized as vitreous has to be called ceramic. Don't look away if you see a floor tile that's not labeled as a porcelain tile. A vitreous ceramic floor tile will do the job you need it to do in your home.

Slip resistance. Another important rating is a given tile's coefficient of friction, abbreviated as C.O.F. The COF refers to a tile's natural resistant to slip and it's measured by the force required to slide an object across a surface divided by the object's weight. Lower C.O.F. numbers indicate less friction and the floor will provide less traction. Higher C.O.F. numbers indicate that a floor will be less slippery.

A C.O.F. greater than .50 is recommended for standard residential applications. A C.O.F. greater than .60 is required for commercial applications and to meet Americans with Disabilities Act guidelines. If you’re looking to tile a bathroom floor, pay attention to that C.O.F rating. The higher the number, the less likely you’ll be to slip when you’re getting out of the shower.

The last two categories are Frost and Tone. Frost is a simple either/or rating and it tells you whether can withstand freeze and thaw cycles outdoors. If you're using a tile indoors, this rating doesn't matter.
And finally, the last category is Tone. Tone only applies when there is intentional variation from tile to tile to mimic the look of natural stone. If you're looking for a tile with consistent color, toned tile is not for you. That category though, is definitely something to look for if you're looking at single tile samples.
