What is a Cast Iron Tub?

In manufacturing, cast iron tub uses a combination of porcelain and cast iron, and later on, the structure is coated with an enamel layer. Cast iron tubs are considered the most durable type of bathtub that is in use and is assumed to last a lifetime. The history of these types dates back to the 1880s. The bathtub is free of chips due to the protective enamel layer and needs less maintenance. Cleaning is also easier with this material. If you have decided to install a cast iron tub in your shower, there is nothing to fear about the cracking too. 

How Much Does a Cast Iron Tub Weigh?

Cast iron is a relatively heavier material than the other varieties in the market. The weight depends on its size. We can expect a cast iron tub to be in the range of 350 – 500 pounds when it is not filled with water. 

You must be extra cautious when transporting this kind of heavy tub because if the surface it rests on does not have enough stability, it will damage the surface and sometimes fall down, making a huge mess.

The weight of a bathtub directly impacts the place where it can be kept. If the material is a heavier type, you have to consider the total weight it possesses when you fill it with water. The average weight of your family members is a measurement to be added to the total weight. If your flooring material does not have enough strength to bear that total weight, you definitely will come across a tight spot. Although there are minor chances of falling the tub from the ceiling, there is a potential risk of damaging some lighter flooring like wood and plywood. 

Therefore, when installing a cast iron tub, you will have to add additional reinforcement for flooring. Often acrylic and stone resin is used to add an extra supportive surface. Additional noggins fixed for the joists will do the job perfectly if you have wooden flooring. Most of the joists would need to be doubled. If it is the basement where the new installation takes place, you will not have to add extra support. We suggest that you take the support of a professional to examine the strength of your flooring.

  • You can use an inclined plane to move the cart if there are steps in your doorway. 
  • If there is a staircase to be passed, you can use a pulley that can bear like 2000 lbs. Connect the pulley to the bathtub with strong straps. 
  • If you have helpers, you could lift it with three people. 
  • If you need to locate the tub in another location on a flat surface, two 2×4 s placed under the tub will make you move the tub by pulling. In this method, do it slowly so as not to chip or crack.
