I am often contacted by designers, specifiers and installers who have been disappointed by the fact that the recently installed light-colored marble shower floor has blotchy-looking wet “stains” that keep growing and sometimes begin to wick up the wall tile.Īs mentioned in my article “ Marble Moisture Discoloration: Don’t Blame the Stone!” (published in the September 2020 issue of the Slippery Rock Gazette), the problem is usually caused by the inappropriate materials and/or installation methods, and is usually a result from the lack of sufficient technical information on the installation methods for this type of stone in shower applications. The discussion of light-colored marble discoloration on shower floors remains an ongoing issue for the tile & stone industry in the United States.
