Bathroom Furniture and Sanitary Ware Design Cascade Collection Washbasin by Corona The Cascade washbasin collection is inspired by the force of the waterfall, a place where water acquires strength and power. The design makes an emphasis on the perceived quality. The thick walls and subtle lines give a bold and refined appearance. The hallmark of these products is a flowing line, a single journey around the product that ends in the characteristic falling movement of the cascade, hinting a slight gesture towards the user. This surface is a design detail that enhances usability and cleanability avoiding spilling water.
