To me it looks like tile set in a brick pattern. Look up types of subway tile.

I agree that these are a form of subway tile, but I am trying to find this shiny brick looking tile and haven't managed to yet. Hoping someone else knows! Thanks all.

I found some options that look just like it by searching for "Mother of pearl subway tiles".

Here's one: Zagora 2" x 6" Glossy Zellige Field Tile in Blanc
