How much does a cast-iron bathtub weigh?

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.

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.
