The PRECIS 25 in SINGLE BOWL ADA KITCHEN SINK offers clean lines and a simple but spacious single bowl design. This ADA-compliant kitchen sink features a reduced bowl depth for wheelchair accessibility and a rear-positioned drain hole, which helps provide knee clearance when the sink is used from a seated position. This kitchen sink is made of SILGRANIT, a patented, certified granite composite material that is engineered to take on the toughest kitchen tasks. Beautiful and highly functional with its non-porous, hygienic surface, it pushes away liquids and residue resulting in a low maintenance, easy to clean, long-lasting material.
