I have white marble in my new shower stall and it a lot has become stained (dark. When our contractor removed one of the tiles, it was wet behind it. He says that the marble is porous and that the water is going through but that does not sound right to me. He also suggested that it may be getting stained from certain bath products which also does not sound right because only regular shampoo and soap is ever used. Amy ideas would be appreciated. Thanks.

 

Dear Liz:

It is simply amazing to me noticing that many consumers like yourself are smarter than some self-appointed “professionals” and can tell the crock of you-know-what that they're trying to deliver!

Yes, you're right: not only isn't there a single marble porous enough to let water through, but the fact in the matter is that most polished marble are not absorbent at all. The baloney of the staining generated by “certain bath products” is, once more, just that: baloney. “Certain products” can etch marble surface, but rarely stain them.

The only reason why you have water behind and under your tiles is because the water found its way through the grout and/or caulk lines. Maybe the grout and/or caulk are missing or cracked; maybe your tile setter felt like being “Italian” that day and installed your tile butt-jointed in your shower stall. No matter what it is, find the real problem if you want to find a solution. From what you're telling me it may not be too late. Unless the tiles have been installed butt-join, that is. In such case there wouldn't be any possible remedy this side of a jackhammer.
