Why gray?? Should have painted the vents to match the wall color. Change the switches and outlets to match the wall color.

I’d consider taking the tile or stone all the way to the ceiling to capitalize on the height.

I thought about taking title or stone to the ceiling, however I just do don't what to choose. And I choose grey because I didn't know what to do with the color which I is ironically the same color as the second image.

To clarify, with gray walls, what color/style (tile or rock)pattern would you recommend for floor to ceiling fireplace?

Here’s a few ideas to get started thinking about an overall design for the room. I like this stone and mantel with your wall color. With the moody walls and dark couch, I’d use a lot of pale colors in the accessories.

Thank you! Fireplace color and style affirming. Our carpet style similar to your recommendation. Accent focal color helpful.

Questions would you happen to have the stone name or sku?

I don’t know the name of the stone. I just grabbed a photo from Pinterest.
