I asked the homeowner and they do not remember what the tile choice was for this bathroom, sorry.

The tile on the floor and the tub deck are the same and the same size. They are turned at different angles. The floor is tiled diagonally. The tiles are ceramic with a printed stone pattern. I think there are 4 different patterns of the tile. You need a competent tile installer to ensure that they are placed in a varying pattern to look like real stone. This bathroom is done with ceramics and travertines to create the look the homeowners wanted within a budget.

What material is the countertop - travertine or granite?

The countertop is ceramic tile that tries to imitate a piece of limestone. The countertop is bordered by travertine trim. The short backsplash has the same ceramic tiles as counter, but a small decorative piece of marble was added on a diagonal. The marble is gold with a rosso piece in middle. An interior designer, Ron Mallot, was very creative in using higher priced materials with lower priced materials to create the look the homeowners wanted, but fit into the budget.

Yes, the shower enclosure has the same ceramic tile on the lower portion of the walls. The listello , like the tub, surrounds the middle portion of the shower or just a little above the middle. Above the listello to the ceiling, the shower is tiled with a diamond shaped ivory travertine. The floor has small 2 1/2x 2 1/2 ceramic tiles that have a rough texture and look like stone. It is enclosed with a glass door. The area around the door and the doorway was trimmed out in the same tile as the floor. They were cut down to fit.
