Marmalade's Masterpiece Bathroom

I am creating a video where a cat-tiler installs tiles on the walls of a bathroom shower. He is a contractor who is renovating the shower. He is a professional tiler with years of experience who knows his job and values it, and he is very meticulous. Actions that take place in the video: he installs large-format tiles, holding them with his hands and placing them on the wall. He also has a trowel, which he uses to apply mortar to the tiles.
