No, traditional tile types such as porcelain, natural stone, and ceramic tile should not be installed without grout. The addition of grout keeps dirt and debris from accumulating underneath the tiles and causing expansion or movement. 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,
no sealant required, and
stain-resistant. The Home Depot's professional installers can assist you in selecting the grout that fits your family's needs and lifestyle.
