No, traditional tile types such as ceramic, natural stone, 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 installation and product. Grout is available in several varieties, including
mold- and mildew-resistant,
stain-resistant, and
no sealant required. The Home Depot's professional installers will help you select the grout that best fits your space.
