Thassos ok for use on shower floor?
Went hunting for marble today and at one of the stone yards, the older Italian owner (who actually pointed out his house next to the Carrara quarry on a photo) told me that doing a thassos mosaic on my shower floor is a horrible idea. Said it will look good for a few years and then the wood subfloor, even though it's under hardibacker or Kerdi, will end up discoloring the thassos. Has anyone else heard this? Does anyone have thassos on a shower floor who can speak from experience? Sometimes I feel like I'm never going to be able to finalize selections for this bathroom!
