The weight of a bathtub can vary significantly depending on a number of factors, including:

  • Material: The material used to make a bathtub is one of the biggest factors affecting its weight. Cast iron bathtubs are the heaviest, typically weighing between 400 and 600 pounds.

  • Size: The size of a bathtub also affects its weight. Larger bathtubs are heavier than smaller bathtubs. A standard-sized bathtub measures 60 inches long by 30 inches wide by 18 inches deep and weighs around 250 pounds. A large bathtub measures 72 inches long by 36 inches wide by 20 inches deep and weighs around 350 pounds.

How to Measure the Weight of a Bathtub

Measuring the weight of a bathtub can be difficult, but it is possible to do with a few simple tools.

Before you begin:

  • Make sure the bathtub is empty.
  • Place the bathtub on a level surface.

Steps to measure the weight:

1. Place a large piece of cardboard on the floor under the bathtub.
2. Stand on the cardboard and step on the bathtub with both feet.
3. Use a bathroom scale to weigh yourself.
4. Subtract your weight from the total weight of the scale to find the weight of the bathtub.

Tips:

  • If you do not have a bathroom scale, you can use a luggage scale to weigh the bathtub.
  • If the bathtub is too heavy to lift, you can use a pulley system to lift it onto the cardboard.
  • Be careful not to drop the bathtub, as this could damage it.
