Generate a side view of the same modern bathroom. Maintain the same floating vanity made of light wood with a travertine countertop sink, matte black wall-mounted fixtures, and a frameless glass shower enclosure. Ensure that the walls and floor are covered in beige travertine marble with natural veining, and the shower area includes a matte black rain showerhead. Use the same design as the front view, maintaining all materials and elements in the exact same positions. Render in 4K to ensure realistic finishes and textures.
