3d and Architectural Penthouse Bathroom Design

I’m looking for an interior designer to create a modern, luxurious private penthouse bathroom measuring 6.5 ft × 15 ft (1.9812 m × 4.6 m). The design should maximize the narrow space and include a vanity with ample large cabinets, toilet, walk-in shower, large mirror, and smart storage solutions. I’m looking for a warm, elegant, high-end aesthetic with premium finishes, refined lighting, and realistic proportions. I also require a clear top view floor plan showing the exact designated location and dimension of every element in both feet and meters. Please provide a detailed 3D design/render showing the proposed layout, materials, cabinetry, and overall look.
