Design a tranquil Surf Shack-inspired spa room with a calming oceanic ambiance. The space features weathered driftwood accents and nautical textiles. Walls are painted a soft, serene blue, while the floor is made of polished white marble. A plush, oversized sectional sofa in a light gray-blue hue is upholstered with a natural fiber throw blanket. The room's focal point is a floor-to-ceiling glass window, providing a stunning ocean view. Warm, golden lighting is provided by pendant lamps made from natural fibers and recycled glass. Aromatherapy essential oils and soothing sounds of gentle waves fill the air. The space includes a rainfall showerhead and a freestanding, soaking tub.
