Houzer E-100 Quartztone Series granite bar/prep sink is a classic square sink for kitchen prep or hospitality bars. Made of 80% fine quartz sand, Quartztone granite material is three times harder than natural granite yet, silky to touch and easy to maintain. The non-porous surface is easy to clean, and deters stains. The material is UV stable and heat resistant to 500 degrees to resist fading, chips, and scratches. Offers a dual mount option for either top mount or undermount installation. Instructions, mounting clips, and a template are included for easy installation.
