Consider the tile's PEI (Porcelain Enamel Institute) rating, which measures surface durability. PEI ratings range from 0 (wall tile only) to 5 (heavy commercial traffic). For residential floors, a PEI rating of 3 or higher is recommended.
Evaluate slip resistance, especially for bathrooms and entryways. Look for tiles with a COF (Coefficient of Friction) rating appropriate for your application. Textured and matte finishes generally offer better slip resistance than polished surfaces.
Plan for grout. Grout color significantly impacts the final appearance. Matching grout creates a seamless look, while contrasting grout highlights the tile pattern. Epoxy grout offers superior stain and moisture resistance compared to cement-based grout.
Consider tile size in relation to room size. Large-format tiles can make small rooms appear bigger by reducing the number of grout lines. Smaller tiles are better suited for shower floors and other areas requiring more grout lines for drainage.
Order 10 to 15 percent more tile than your measured area to account for cuts, waste, and future repairs. Tile dye lots can vary, so purchasing all your tile at once ensures consistent color and pattern.
