Large-format tile — generally anything over 15 inches per side — delivers a clean, nearly seamless floor with a fraction of the grout lines of standard-size tile.
Large-format porcelain, including slabs up to 5-by-10 feet from some manufacturers, minimizes grout lines for a more monolithic look. It's increasingly common for kitchen and living space floors as well as shower walls.
Open-concept kitchens and living spaces where a continuous floor reads larger and cleaner; shower walls, where fewer grout lines mean less to clean.
Large-format tile requires a flatter subfloor and more meticulous installation — lippage (uneven tile edges) is far more visible at scale. We only recommend installers experienced with large-format setting techniques.
Generally any tile over 15 inches on a side, though the category extends up to large-format porcelain slabs measuring several feet across from some manufacturers.
Typically yes — it requires more substrate prep, specialized setting tools (like suction-cup lifters), and often a large-format tile mortar, all of which add labor cost.
Yes, and it's increasingly popular for shower walls specifically because it minimizes grout lines in a wet area.
Ask your installer specifically about their experience with large-format tile before committing to it — substrate flatness tolerances are much tighter than for standard-size tile, and it's not a good place to learn on the job.
We'll help you compare it against the other options for your specific room.
