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