No, traditional tile types such as natural stone, ceramic, and porcelain tile should not be installed without grout. The addition of grout keeps dirt and debris from accumulating underneath the tiles and causing movement or expansion. Grout also keeps moisture from penetrating under the tiles' surface, which can shorten the lifespan of the installation and product. Grout is available in several varieties, including
mold- and mildew-resistant,
stain-resistant, and
no sealant required. The Home Depot's expert installers will help you choose the grout that fits your family's needs and lifestyle.
