Create a master bathroom that reflects the divine authority and splendor of Egyptian ceremonial spaces. Place a jacuzzi at the center, flanked by throne-like seating with elaborate carvings and opulent fabrics. Include a bathtub with a high back and sides, decorated with hieroglyphics and gold inlays. Add a sauna with intricately carved wooden benches and walls adorned with Egyptian symbols. Use a luxurious color palette of gold, black, and deep reds, and incorporate elements like large mirrors, rich textiles, and marble flooring to complete the design.
