List every place the floor stops
A floor tile proposal should list every place the new floor meets another material or a change in height: a doorway, a tub, a cabinet toe, a slider track, or a step. Thresholds, reducers, and metal or stone edges are separate pieces. They are not included merely because the field tile appears on the material list.
Walk the perimeter and write it down
Start at the door you enter and name each stop in order. At a doorway into another flooring, say what that other flooring is and whether the tile dies against it, overlaps it, or meets it with a reducer. At a tub or a shower, say which edge piece meets the fixture. At cabinets, say whether the tile slides under the toe or stops at a finished line the cabinet will cover. A count of edge pieces without locations cannot be checked.
Height has to be absorbed somewhere
Tile plus a new backer can sit higher than the floor in the next room. The proposal should say whether that difference is taken up by a reducer, by recessing the assembly, or left as a step. Ignoring the difference does not keep the two floors at one height. The edge piece is how the scope admits the difference.
One-piece items still get a line
A single stair nosing, one outside corner, or the strip under one door is easy to leave off because the count is small. Those pieces are where the finish is judged. Write them even when the quantity is one, and say whether the piece is metal, stone, or a manufactured trim. This note does not require a brand.
