Eljer has announced the Gibraltar bathtub, featuring a heart of EnduroCAST(TM), a revolutionary new core material identical to what the automotive industry uses for crash-protection. Weighing 89 pounds, the Gibraltar is easier to move to an installation site and requires less manpower to install. And thanks to the dual stabilizing bars on the underside of the tub, it sits flat on the floor, so no leveling is required. Eljer. Circle 18.
