Montagna Rustic Bay 6 in. x 24 in. Glazed Porcelain Floor and Wall Tile (14.53 sq. ft. / case)

You should call your local HD. They might have a professional installer they can put you in contact with.

The edges are not terra cotta. They are grey like the facade.

Yes. I don't have a pool but I installed this on the walkway leading to my front door about three or four years ago. It is suitable for outdoor installations. The surface is textured. Not slippery, even when it rains.

Yes, I believe you would be able to, its porcelain tile. You could install this in a wet area like a shower and it would be fine so I cant see a steam mop being a problem.

Yes, We did a shower using this tile. The only issue is that the tile is 24 inches long which restricts the layout options in a smaller space.

I would probably not use this, or any other, tile on a ceiling due to the weight factor. Best wishes with your project.

I don't consider them beveled or rolled. They are pretty crisp, but have a slight roll at the very tip edge so you don't cut yourself on the edge. Best wishes with your project.

Yes, Any porcelain tile such as this should work on a prefab fireplace front. Porcelain tile is considered non combustible. It should pass any local building code, but I would check first. They may want you to make sure to use a grout joint right up to the edge of the prefab firebox. Caulk joints will not work unless it is a fireproof / fire rated caulk. That may likely be unacceptable since most fire caulks are red so they can be identified. I suggest using a sanded caulk that will match the grout color and texture. Home Depot has a good selection from which to choose. I'm attaching a photo of this tile used on a floor in a room with a prefab fireplace which utilizes a slate surround for illustration. Best of luck with your project.

Home Depot does installation. Ask at the flooring department. They should be able to gladly assist you. Best wishes with your project.
