Design a master bathroom that embodies the splendor of ancient Egyptian ceremonial spaces. Install a jacuzzi with surrounding seating that mimics the appearance of thrones, complete with carved armrests and plush cushions. Incorporate a bathtub with an ornate headrest and footrest, echoing the style of royal Egyptian furniture. Add a sauna with wooden benches adorned with gold leaf and hieroglyphic engravings. Use luxurious fabrics, marble surfaces, and gold fixtures to create a space fit for royalty.
