Many manufacturers offer customizable fibreglass water tanks to suit specific customer requirements, such as unique shapes, colors, and fittings. Customization can significantly impact costs. Standard designs are generally more affordable; however, if you require a tank designed for a specific purpose (like rainwater harvesting or water treatment), expect to pay a premium for the custom features. Custom tanks can range from $2,000 to upwards of $10,000 based on the complexity of the design.
