The McAlpine WHB-1 Wash Hand Basin and Bath Space Savers with Self-Closing Waste Valve are plumbing fixtures designed to save space in bathrooms. The WHB-1 is a compact wash hand basin that can be installed in small bathrooms or cloakrooms. It has a self-closing waste valve, which prevents water from draining out of the basin when it is not in use, helping to conserve water. The basin is made of vitreous china, a durable and easy-to-clean material. The Space Savers are bathtub waste and overflow units that also feature self-closing waste valves. They are designed to fit into the limited space available between the bathtub and the wall. They are available in different configurations to fit different types of bathtubs. Both the WHB-1 and the Space Savers are made by McAlpine, a UK-based manufacturer of plumbing products. They are designed to be easy to install and to provide reliable and efficient performance. ・ Side inlet connection for 19/23mm condensate or condense drain ・ 1.25" BSP
