As an industry leader, Novatto uses advanced technology to produce beautiful glass vessel sinks with unmatched structural integrity and longevity. Constructed of thick 3/4-inch high tempered glass, Fiche is a double-layered round vessel sink with a design of koi fish on a dark background. The design pattern is locked between two layers of glass ensuring years of beauty. Internal testing has found these vessels to be very durable and forgiving. Made with the highest standards of quality and creative design, Novatto sinks add art and function to any bath or powder room at an affordable price. Fiche has a standard 1.75-inch drain opening. The set includes a chrome pop-up drain and matching mounting ring. For best cleaning results, apply the included Glacier Ice as recommended. Novatto's Glacier Ice wipe-on treatment is a hydrophobic sealer used on glass, ceramics and faucets. Glacier Ice inhibits the growth of pathogens while preventing mold, mildew, corrosion, oxidation and dirty mineral buildup caused by hard water! Apply just once a year to keep your sink or faucet looking like new. Package includes an eco-friendly presoaked wipe-on cloth and one microfiber cleaning towel.
