Marine fresh water tanks are essential for safely storing potable water, graywater, and wash water on boats and marine vessels. Our boat water tanks are made from FDA-approved, virgin polyethylene marine tanks, offering strength, safety, and versatility. These marine holding tanks are fully enclosed with a 3/8" wall thickness and manufactured through a roto-molded marine tank process for long-lasting, leak-proof performance.
Our custom marine water tanks are engineered for boats equipped with plumbing systems, including yachts, sailboats, and fishing boats. These tanks are designed to store clean, drinkable water and are available in multiple shapes: bow, rectangle, and wedge. All models feature one-piece, seamless construction and are built to last with FDA-approved, NSF-compliant marine-grade polyethylene.
Our tanks are a blank canvas, allowing us to customize tanks to your exact specifications. Rotate your tank any way you need to fit your unique requirements. All of our tanks have female NPT openings in the same position on one end, so they are suitable for all marine plumbing needs. You can easily drain water from all of our tanks, preventing damage from freezing temperatures during the off-season. We offer custom marine fresh water tanks and spin-welded fittings for the unique size and fit of the tank you need. Choose One Clarion for the highest quality marine tanks on the market!
