Add a splash of drama to your bath with some bold red. As an industry leader, Novatto uses advanced technology to produce beautiful glass vessel sinks with unmatched structural integrity and longevity. Constructed of thick 1/2-inch high tempered red glass, Rosso will add a punch of color to your decor. Tempered glass cannot be compared to everyday synthetic porcelain and ceramics. Internal testing has found these vessels to be very durable and forgiving. Items such as toothbrushes or small jewelry should not scratch the surface. Made with the highest standards of quality and creative design, Novatto sinks add art and function to any decor at an affordable price. Rosso has a standard 1.75-inch drain opening. The set includes a matte black 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 prevents corrosion, oxidation and dirty mineral buildup caused by hard water! Apply just once a year to keep your sink or faucet looking like new. Proudly made in the U.S. Let your style flow and enjoy Novatto's Limited Lifetime Warranty. Supreme packaging and boxing ensure damage-free delivery. Novatto's customer service is always here to answer any additional technical product questions or help you choose a matching faucet.
