Large-format natural stone tile is in demand for a variety of reasons. Designers like the aesthetically pleasing, open look it gives floors and walls in residential and commercial applications. Consumers like the natural beauty of a large stone expanse and appreciate the easier maintenance resulting from fewer grouted joints. But large-format tile also has its installation challenges. Working with large-format stone requires tighter tolerances in the substrate. In addition, its weight makes it harder to handle in both floor and wall applications.
