I was on the Porcelanosa website and there are many tiles (and a bit difficult to differentiate online). Would you be able to say what the name of this particular tile is?
Thank you.

what is the name/specifics of that tile??

It is Porcelanosa, comes in 3 colors. I think the one shown is "Shine Dark": http://www.porcelanosa-usa.com/home/products/tile/wall.aspx/d=15428/title=Shine_Dark

Thank you for including this information. I'm very interested in this fireplace design and just ordered several samples from Porcelanosa. Thank you so much!

Adding this from Porcelanosa: "Ferroker is a porcelain tile. It is an “Image” as it is a manmade material. It’s mimicking a steel but some think its more of a concrete." I had expected this to be a shimmery stone or concrete but it's definitely an image printed on top of porcelain. Not what I was expecting so I wanted to share should it be helpful to anyone else.

would love to know artwork as we'll!

Can you share the overall height from floor to top of the mantle? Thank you.
