The term refers to a specific style of vitreous china lavatory fixture, distinguished by its sleek, minimalist design and high-efficiency flushing mechanism. This type of fixture often incorporates a concealed trapway, creating a seamless and aesthetically pleasing appearance. An example would be a modern, wall-mounted unit with a square or rectangular bowl.
Such fixtures offer several advantages, including water conservation due to their optimized flushing systems, and ease of cleaning thanks to the smooth, unbroken surfaces. Historically, this design reflects a broader trend in bathroom fixtures towards minimalist aesthetics and increased functionality. The development of advanced ceramic manufacturing techniques and water-saving technologies has enabled the creation of these highly efficient and stylish bathroom elements.
