Hi @Debbie Zolnierowicz, that is great you are keeing slip resistance and coeficient of friction in mind for your shower floor. We have not had any feedback or concerns from our client about slip resistance. This installation in the photo is not the Anatolia Soho glazed ceramic you are mentioning. Maybe another user commented that that was similar to the product we used. What is shown is a marble floor mosaic. The small size (about 1" each piece), crisp edges, and grout between each, makes for a grippy floor. I can't advise on using the ceramic mosaic, as I am not familiar with it, but this marble one has been safe for our clients. Thanks for your question!
