We take baths to wash ourselves but also to relieve fatigue and relax. After observing the relaxing effect of bathing over many years, we designed this bathtub and washbasin based on real-life tests. The rectangular form conveys both a sense of tension and relaxation. The matching designs of the bathtub and washbasin give the bathroom a premium feel. The bathtub is shaped in a way that encourages people to adopt an ergonomically relaxed position that helps relieve physical stress. The shape of the washbasin makes handwashing enjoyable and prevents splashing. These factors visually and physically enhance the bathroom environment.
