This new release of the Stanwell™ urinal features the same streamlined style and dimensions as the original but with new enhancements including a more water efficient flush rate of 0.5 to 1 gpf. The inlet spud has been reduced from 1-1/4 in to the industry standard 3/4 in. Rough-in and wall-print dimensions remain the same as the K-4972 Stanwell™ and the powerful blow-out action flushes like a bowl and offers quiet performance.
