Eljer has introduced the Gibralter™ bathtub made with EnduroCAST™ , a core material the company says is identical to what the automotive industry uses for crash protection. The tub weighs only 89 pounds and has dual stabilizing bars on its underside so it sits flat on the floor without the need for leveling. It is offered for commercial and residential applications in white, natural and biscuit and comes with a limited lifetime warranty.
