Hi - I'd invite you to check out our Cottage Craft Tile website \ plenty of photos of finished fireplace projects with a vintage/ transitional feel. The fireplace is generally the focal point of the room and choosing the right material can make all the difference / good luck with your project!

We need to know a little more about your style, but I would say - real stone. That will give you a timeless look. Something neutral . . . marble is a great one for a traditional / classic feel like your mantel.

You have tons of options! Personally, I'd go with soapstone or slate. I think those would look best with your floors.

Maybe a nice neutral stone? Ledgestone?
