Single hole lavatory sink. Thoroughly modern and luxurious Toto's Supreme Suite is all about understated elegance. Having no extraneous details to interrupt the beauty of its lines this Suite is at home with a variety of bathroom furnishings. TOTO’s patented super-smooth SanaGloss glaze prevents debris mold and bacteria from sticking to porous ceramic surfaces. SanaGloss keeps your chinaware cleaner longer which means fewer chemicals in the environment and less water used for cleaning. SanaGloss seals china with an ionized barrier creating a super-smooth surface that prevents particles from adhering to ceramic while a catalyzed ion barrier actually repels particles away.
