Design a modern bathroom featuring a sleek, minimalist aesthetic. The walls are adorned with elegant marble, showcasing both light and dark veining. Highlight a compact yet stylish vanity with a smooth countertop, seamlessly integrated sink, and minimalist faucet. Above the vanity, include a backlit mirror that enhances the contemporary look. On one side, create an organized shelving unit with ambient lighting that showcases neatly arranged toiletries and decorative items, emphasizing functionality and elegance. Next to the shelving, position a sleek, modern toilet with a flush panel that blends seamlessly into the cabinetry. The overall color palette should be neutral, with hints of warm wood tones for a sophisticated and inviting atmosphere.
