57 Gallon RV Fresh Water Tank - Durable Potable Storage

In this review of the 57 Gallon RV Fresh Water Tank the bottom line is simple: it is a large, straightforward freshwater solution for RV owners who need reliable potable storage. The tank is aimed at campers, trailers, motorhomes and tiny houses that require a sanitary, high-capacity reservoir for drinking, cooking, showering and washing dishes. The single biggest reason to buy is its combination of true 57 gallon capacity with BPA-free, USA-made construction that prioritizes hygiene and durability.

Key Features

• Made in USA: The tank is manufactured in Elkhart County, Indiana, offering domestic production and consistent quality control for RV plumbing.
• BPA-Free materials: Constructed from sanitary plastics that reduce chemical leaching, making it suitable for drinking and cooking water storage.
• Multiple fittings: Built-in fittings include two 1.5in balloon style threaded female NPT and two 0.5in threaded female NPT, which provide flexible plumbing options during installation.
• Durable construction: Weather resistant and impact-resistant plastics give the tank a rugged feel that stands up to mobile use and prevents leaks when installed properly.
• Large capacity: At 57 gallons and a cube shape of 43in x 25in x 13in, it supplies extended off-grid water needs without occupying excessive floor footprint.

Who It's For

The 57 gallon tank is best for RV owners, tiny house builders and food truck operators who want a large, sanitary freshwater reservoir that fits a rectangular space. It suits people who prefer a robust, USA-made part and who plan installations where multiple built-in fittings and a predictable capacity are important.

It is less suitable for systems that require pressurized tanks, for installations that must hang the tank by straps, or for buyers who expect included mounting hardware, valves or hoses, since those items are not supplied with the tank.
