Washbasin made of stainless steel, material no. 1.4301, with integrated self-closing knee valve and a hand-operated volumetric hot-cold temperature mixer with one inlet each for hot and cold water. Two check valves (for the hot and cold water pipes) must be provided by the customer! Outlet arch standing in the middle of the rear edge of the pool. By using a jet regulator with flow limitation, the throughput is reduced from approx. 14 l/min to approx. 7 l/min and thus the water consumption per washing process is reduced! The pool is equipped with appropriate holes for attaching the pool to a solid building wall. Screws and dowels must be provided by the customer.
