Samples by format
Flat tile is the largest group, then mosaic, then paving, planks and trim. Ledger panels, accent pieces and bases all appear too.
Being able to sample a molding matters more than it sounds. A trim piece has to agree with the floor in color and in sheen across a curved or angled face that catches light differently from a flat one, and that is the match hardest to judge from two photographs taken under different lighting.
What a tile sample is
Not a printed card, not a reproduction, and not a special manufacture for the purpose. It is cut from the same production as the product it represents, which is why it can settle the questions it settles.
It is also a sellable unit of the same SKU rather than an offcut, which is why a sample of a mosaic arrives as a piece of sheet and a sample of a paver arrives with the thickness a paver has. The weight in the hand is part of what you are being shown.
Seeing a sample in room light
A screen shows a color lit from behind at a fixed temperature. A room lights the same surface from the side, from above, in daylight that changes hour by hour and in whatever bulbs are fitted.
So the useful thing is not to look at a sample once, but to leave it in the room and catch it at different times: morning, afternoon, and under the lights in the evening. Beiges and grays move the most, which is exactly where the catalog is most crowded.
Color, material and texture
The material, first: a piece in the hand tells you whether something is a fired body or quarried stone in a way no photograph does. Then the surface, because a matte face and a honed one feel different under the fingers and photograph identically.
Then the two comparisons that actually decide a room: the sample against the counter, the cabinets, the paint and the wood that are already there, and the sample against the other candidates in the same light. Choosing between two pieces side by side is a far easier judgment than choosing one in isolation.
What a sample cannot show
How a floor of it will look. A sample is one piece and a floor is hundreds, and for anything with real variation those are different objects. The composition of a veined marble, the way a blend distributes its colors, the scale at which a pattern repeats: none of those exist at the size of a sample.
Format is the other blind spot. A large format tile changes a room by having few joints in it, and a small piece of one cannot show that. The bigger the tile and the more it varies, the more the sample is telling you about the product and the less about the result.
Shade variation and samples
Tile that publishes a variation rating is telling you in advance how much two pieces will differ. At the low end a sample is close to a promise; at the high end it is a member of a family and nothing more.
So the rating decides how much weight to give the piece in your hand. A heavily varied range judged from one piece is where the surprises come from.
Stone and mosaic samples
Two formats move the question somewhere else entirely, and both have their own page for it. With quarried stone the question stops being about the sample and becomes one about the lot, which the stone tiles range explains. With mosaic it stops being about the pieces and becomes one about the sheet, which the mosaic page sets out.
Everything else on this page applies to both. Those two are simply the places where holding one piece answers less than it does elsewhere, and where the right follow up question is a different question rather than a second sample.
Outdoor paving samples
A paving sample is judged outdoors, against soil, planting, brick and whatever the house is built of, and in daylight rather than under a bulb.
It is also the one case where wet matters: an outdoor surface spends part of the year wet and a great many stones look like a different product when they are. Running a sample under a tap is the quickest test nobody thinks to do.
Comparing a shortlist
Three or four candidates, all in the room at the same time, beside the fixed materials, seen over a couple of days. That is what settles it, and it settles it faster than any amount of screen time.
The range each sample comes from is where the rest of the decision lives: the floor tiles page for the flooring families, the porcelain tiles and stone tiles pages for the two big material camps.
