Made from ultra-high performance concrete (UHPC) in a single casting; the basin features a large chamfered edge design, exuding a refined and sophisticated look while maintaining a clean finish. This minimizes the appearance of holes, resulting in a dense and uniform surface. A surface coating significantly enhances its waterproof and stain-resistant properties. Driven by a meticulous attention to detail, the concrete drain fittings are independently designed. When drainage is needed, the lid pops up, leaving a gap of approximately 3mm for drainage and also providing some filtration; when filled with water, the lid is flush with the bottom of the basin, maximizing the overall uniformity of the product.
