Never assume a room is perfectly square – always square off from the center and begin floor tile pattern along one edge.
To avoid rough edges on tile, always float the floor to a level state before installing tile.
Always round to the next highest footage when calculating square footage of tile needed.
Random is not a pattern for floor tile but a specific look designed by the installer. Most random arrangements need to work on these percentages:
• 12″ x 12″ 60%
• 6″ x 12″ 40%
• 6″ x 6″ 40%
When installing tile in a random configuration, the percentages of tile for the three sizes involved do not add up to 100%, in order to allow for different looks throughout the installation. These percentages will also allow for coverage needed due to centering of the layout.
• Modular patterns, if laid according to this guide, will have a solid grout frame every three feet.
• Each diagram represents nine square feet.
• A dark outline on the pattern indicates where tiles begin to repeat
