A tiled shower can significantly upgrade the look of a bathroom, but hairline cracks in the tile grout can be a troublesome source of water leaks. Learn how to prevent tiled showers from leaking by sealing the grout.


To get more years out of your tiled wall, seal all of your grout with clear silicone (available at hardware stores in spray- or brush-on formulas). It will not only add luster to the finish but will also seal the grout’s pores against bleach. Bleach, because it kills mildew, is a common ingredient in bathroom and household cleaners. Unfortunately, it eats into porous materials like grout, causing them to deteriorate. Remember that with a tiled wall, it’s rarely the tile that goes bad or wears out—it’s the grout.

If you are regrouting, consider using a silicone-based grout additive that contains mildewcide (available at hardware stores). The grout will last longer, and you’ll have less cleanup work.
