Cast-iron bathtubs range in weight from approximately 225 pounds for a 48-inch classic clawfoot tub to 500 pounds or more for a 72-inch pedestal tub. The classic model is a smaller tub with four short legs, and the pedestal is a large tub with a built-in base.Know More
Bathtubs made of cast iron come in many shapes and sizes. The smaller tubs weigh less on average, although different tub lengths and volumes bring variations to weight. For instance, a clawfoot tub with a volume capacity of 30 gallons may weigh less than one with a 37-gallon capacity, though both may be 48 inches long.
