Bath ladders are made of polished AISI 316 stainless steel with tilting fittings at the top and adjustable feet. Polypropylene steps.
Also the hinge so the ladder can be folded in half. The top bracket can be replaced with a hanging bracket, so that the ladder can be removed in a snap. The steps can be adjusted so that the feet always step on a horizontal surface - a good safety factor.
Tested in a saltwater simulator to ensure they can withstand the maritime environment. Choose a bathing ladder that has 2 steps in the water when it is unfolded.
