Design a serene Japanese-style spa room with natural materials and calming colors, featuring a soaking tub made of gleaming white Carrara marble, surrounded by a floor-to-ceiling wooden screen adorned with intricately carved shoji panels. The room is bathed in soft, warm lighting from paper lanterns and candles, while the walls are clad in soothing shades of pale wood and moss-green ceramic tiles. A low, cushioned futon-style bed is placed under a stunning wooden shoji screen, and a floor-level cedar wood soaking tub is positioned in a tranquil corner, complete with a delicate wooden water ladle.
