Go to a tile store, and look at faux marble porcelain tile, and at real marble. Take your WALLET for the latter. $$$$$$$$$$$$

Have you tried taking the image and using Chrome to do a search of the internet and see where all it is posted and if any additional information is available? Other than that, I don't know how someone else could identify it. Depending where you are, most cities have multiple tile stores that could help you source something similar.

I have not tried the Google search but I will. Thanks Brickwood.

Thanks Sophie.

Jan I am looking just really haven't found many faux marble similar to the pic. We do have some though.

I appreciate the responses.

The tip that this is the real thing is the complete lack of any repeats (or many grout lines). Even a good faux marble is unlikely to have more than 6-8 different designs.

It's a tile and not a slab as I see actual 12x24 size on the back wall. Grout joints are faint but they're there. Looks to be actual marble due to no repeat prints and high movement. Looks as if they also used a 5/8x5/8 mesh on both walls that have fixtures and knobs. That same size (5/8x5/8 mesh) is also used on the wet floor in a different color.

On first glance it looks like marble. I'm not sure. However, there are wonderful options made in porcelain today. Check out both options and see how the bids come out.

You can come closer to the look of real marble by selecting a porcelain tile that's available in several sizes. A stellar Pro tile setter can arrange the tiles so that the "repeat" is less obvious.

The only problem that I encounter when using different sized man made tiles is that the color dye lot and calibration will most likely vary. The different sizes are made in different locations at the factory so getting the same dye lot and calibration is slim to none.
