      Wholesale Marine carries a selection of marine holding tanks for any size craft. Also known as waste tanks, these multipurpose containers can be used as a dedicated container to hold either fresh water supplies or marine toilet waste. Wholesale Marine carries tanks that are made from one-piece molded durable polyethylene, with no seams to crack, and meet Coast Guard regulations. Our tanks are durable, too, and feature heavier walls and openings molded to prevent stress cracks and leakage.
