These are Tex by Mutina.

Thanks so much!

A couple more questions. Do you know of anyone selling this in the USA? Also, it looks like there are some non standard colors in your design (your bathroom has more variety to it than they show on their website). Thanks

Stone Source carries Mutina.

The colors are standard, check the colors and combinations on Mutina's site. https://www.mutina.it/en/collection/tex-by-raw-edges?samples=open

Thanks!
