Hi there-- thanks for your question, This bathroom is several years old, and I don't quite remember the color name, but the tile was from Sonoma Tile Makers https://sonomatilemakers.com/

You could also get a similar look from Fireclay Tile www.fireclaytile.com or Heath Tile https://www.heathceramics.com/

It is handmade ceramic tile. Happy remodeling!
