Gray Marble-Look Shower With a Chevron Mosaic Wall

The first photos show the cement board walls with seams and the window opening treated before tile, and the floor prepared for a linear drain.

In the finished shower, large-format gray marble-look porcelain wraps the window with a slim dark edge trim, a white chevron mosaic covers the accent wall, and a gray hexagon floor runs to a black linear drain. Two corner shelves sit in the back corner.
