Hello Partners,
Thanks in advance for any help/ insight you can give me to help this customer.  This stain on a marble shower wall started about 12 years ago.  The first 2 photos show it in 2008 and the last photo is recent.  I did not see it in person; these photos were sent to me.  The first 2 older photos also show staining on the floor tiles and grout, but the newer photo shows a cleaner floor.  Obviously, I am thinking a rust spot behind the marble.  Any ideas on a "cure"?  Also, any ideas on the stone I.D.  I thought a carrara , but my contact believes that it is a more rare variety.  I ask this because a good option is to replace because the problem behind the wall needs to be addressed.


Thank You,
