Red, I'm linking to a thread on another site where the OP was dissuaded against using Thassos. However, one mainland Greek wrote to say:
"You do not buy Thassos marble for ease of maintance. You buy it because you will have in your bathroom the same material dug out from the same spot as were various masterpieces sculpured in ancient Greece and now residing in the Louvre (Paris-France)and other museums all over the world."

Yeah, that stuff is beautiful. I almost bought it for my powder room floor, but then decided I'd never be able to maintain it. My powder room is the dirtiest room in the house. :l

Well that description about Greece is enough to make me want it!!

I still want Calcutta extra...but if DH really is opposed against the veining, I'm still going to consider Thassos. I'm very neat and he's fairly neat, and I was planning on putting all our hygienic products on a tray. So hopefully it will not damage the marble...and if there's a spot or two I think I can live with it.
