LOS ANGELES, Jan. 9, 2013 /PRNewswire/ -- Caesarstone USA (NASDAQ: CSTE) announced today that sinks made from its quartz product by Sonobath are available for commercial installation. Handcrafted from Caesarstone, Sonobath sinks have earned an IAPMO certification which now allows them to be used in­­­­ restaurants, hotels, and other commercial projects in addition to residential designs.

The IAPMO certification provides an added sense of confidence for design professionals and individual customers ensuring them that the sinks have passed the most rigid independent testing for quality and performance. These sinks will now meet the regulations required by commercial building inspections.

"Sonobath sinks' IAPMO certification is a high distinction, of which Caesarstone is proud to be part," said Sagi Cohen, CEO of Caesarstone USA. "Our partnership with Sonobath allows us to continue our support of architects and designers as they design for the high standards of commercial spaces."

"The quality and consistency of Caesarstone quartz is a key element of the IAPMO certification. Sonobath is one of the only IAPMO-approved high-end, high-design fabricated collections of bath fittings on the market today," said Jae Omar. "Our sinks capture the imagination when used in designs, yet they offer third-party validation for their real-world practical utility as well."

Offered in a variety of Caesarstone colors and custom sizes, the IAPMO-approved sinks include the popular Sonobath HYDROS, FLOATING HYDROS, ETHOS, LOTUS, and TITUS. Each takes the concept of a vessel sink into a new dimension of intrigue and style, with nature-inspired designs and hidden drain systems.

Sonobath sinks currently are found in fine hospitality and custom residential applications throughout the country, including multiple installations in the Club Nikki/Nikki Beach at the Tropicana Las Vegas.
