A modern bathroom with a minimalist design, featuring black and white marble walls and a walk-in shower. the walls are covered in dark, glossy black marble with a glossy finish, and the floor is tiled with a light beige marble pattern. the shower area is enclosed by a sliding glass door, and there is a large mirror above the sink. on the right side of the image, a black sink with a black faucet sits on a white countertop, with a small vase of white flowers beside it. a beige toilet is placed on the floor next to the sink, adding a touch of elegance to the otherwise monochromatic space. the overall aesthetic of the bathroom is sleek and contemporary, with minimal details and a focus on textures and lighting.
