No, traditional tile types such as ceramic, porcelain, and natural stone 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
stain-resistant,
mold- and mildew-resistant, and
no sealant required. The Home Depot's professional installers can help you select the grout that fits your family's needs and lifestyle.
