The Q811TBE sink has numerous exciting features, not the least of which is its Quartz Granite composition. A balance of 80% quartz and 20% acrylic, makes for a very dense, nearly impervious substance with a very attractive, satiny-smooth appearance. It is nearly impossible to scratch or stain because of its density, and it can withstand extreme temperatures - a dropped knife will not scratch, acidic foods will not stain, and hot pots will not burn the surface. No sound-dampening pads are required because Quartz Granite is inherently quiet. The Q811TBE model is designed for mounting over the countertop. Its low divide and deep bowls provide more functionality, especially with large pots and pans. The overall measurement of 33" x 22" x 10 1/2" will require a minimum-width cabinet of 33".
