First, remember, most bathrooms today are using larger tiles. 8″ x 10″ tiles have 38 inches of groutable edge, while the old style 4″x 4″ tiles would have 80 inches of groutable edge, so you’d greatly reduce the grout area and the maintenance.

Grout is porous giving it the ability to absorb liquids, including those that can leave behind a residue stain. A silver or beige floor grout can help to make staining less noticeable. For walls, white tends to have the “cleanest” look.

Sealing of the grout can help reduce staining as well. Sealing should be done a few days after the project is completed to prevent trapping moisture in the grout or setting materials. The homeowner can do this with a bottle purchased from Home Depot or Bonnie Tile or anywhere you might buy tile. There is even a new spray on, self dispersing version, that, according to the label, does not even have to be wiped down.
