Thread: Caulking around the shower

  1. #1

    Default Caulking around the shower

    I just installed a new shower complete with tile floor and it looks beautiful. Is it necessary to caulk the perimeter of the shower floor where it abuts the wall or is a good grouting job sufficient. I'd hate to ruin the nice looking grout with caulk if I don't have to. Also, should I caulk the corners of the wall or is the grout good enough. Thanks, Frank

    If the whole job was done right and no corners cut every thing is solid and you keep the area clean and dry between uses, and maintain the grout by cleaning and resealing when necessary I wouldn't caulk.

    Thanks Cass. That's what I was hoping.

    The Tile Council of America (TCA) is the basis of the codes on shower installation for most of the country. They say do not grout the changes of plane in a shower (i.e., the corners and the wall/floor interface). Instead, use caulk. This is because few showers will be expanding and contracting the same between those corners, and the grout will likely crack. If your shower was built very carefully, you might get by with that and not have it crack, but that is actaully rare. If you've already grouted them, leave it alone and see. If it does crack, then you'll need to remove the grout, and replace with caulk. Caulk over grout never works for long, and usually looks lousy. You can buy caulk color matched sanded or unsanded grout for nearly any color grout; you may have to special order it, or get it on-line, but it is out there.

    Thanks, The tile store sold me the color matching caulk, but I'll wait and see how the grout holds up.
