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.
