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