Interestingly, clawfoot tub styles vary in weight due to the material it is made of. Bathtubs are typically available in acrylic, cast iron, resin-stone, marble, stone, and wood. Each of these types of tub weighs differently but some are similar in weight based on the structural material.
Please note that the weights mentioned here are approximate and based on an empty bathtub. A clawfoot 60-inch acrylic tub weighs 75 pounds and a 60 inch cast iron clawfoot tub is 325 pounds. A larger, 70+ inch acrylic tub with clawfeet is about 160# and in cast iron 468# is a common weight for a similar size and style tub.
Similar-sized double slipper freestanding tubs in wood are 125#, cultured marble is 280#, and mineral composite tubs average 253#.
A gallon of water weighs 8.35 pounds. Water is typically measured by its volume. If a tub accommodates 46 gallons of water then add 383.129 pounds to the weight of the tub for the total filled weight.
Hopefully, this information has been helpful to you in weighing the pros and cons of different sizes of tubs and the materials of which they are available.
