tile help! what is wrong with my shower floor?!

stephcaldwell179February 12, 2014

What are all these dark spots on my shower tile floor? It's a marble tile purchased from Lowes. I've used every cleaning product (even heavy duty stone and marble cleaners) and nothing has worked. No, it was not sealed initially. I tried cleaning it and then sealing it and it did nothing. What should we do? It's a new home and tile has been there for about 5 months now. It looks so bad in person! Eek!

It looks like moisture trapped in the floor.

We would have to know more about how the floor was laid.

Rubber liner BETWEEN a pre-slope and a final slope OR a Surface Applied Membrane over a single mud bed.

Another thread with similar issue.

Jump on this immediately with the builder while your warranty is still in effect.

Oh boy. We have the identical problem. Look at my thread to see good advice. Nobody wants to redo our floor, unfortunately.

Ours got worse since I took this picture in 2012. Nobody wants to fix our floor, unfortunately.

Please do post how you resolve yours and, when something happens with mine, I will do the same.

Unfortunately, the ''Fix'' is to redo the shower. Do it with a different waterproofing system. A painted on membrane on top of a proper preslope will let porous materials dry out because it only gets wetted very shallowly. Or you can live with it as is until you are sick of porous natural stone and ready for the faux.

Did you see the soap scum problem in AZmom's recent thread? Sure looked like water too.
