How much water in a waterbed tube?

The amount of water in a waterbed tube typically depends on the size and design of the bed. A standard waterbed can hold anywhere from 150 to 400 gallons of water, depending on whether it’s a softside or hardside model. Each tube in a waterbed is designed to accommodate a portion of this total volume, so the specific amount will vary based on the bed's configuration and dimensions. Always refer to the manufacturer’s specifications for precise measurements.
