Equipped with a drain trap. (WA00231) The "Elegance" washbasin boasts a sleek design with a thinner rim for a sophisticated look. Its sharp edges reduce the sense of weight, creating a smart and modern impression. Please note that the drain opening is European standard, so you must purchase the necessary drain hardware along with this product. (Domestic traps are not compatible.) As this is a ceramic product, there may be dimensional tolerances of approximately ±5% of the stated size according to JIS standards. Please confirm the actual product before installation. This is a heavy item, so ensure adequate backing is provided and secure it with anchor bolts during installation.
