While a cast iron shower pan is elegant, strong, long-lasting, scratch-resistant, and easy to clean, it also has some drawbacks. It is the highest-priced shower pan material available. It also comes in a restricted range of colors, can be slippery when wet, weighs a lot, and is prone to rust.

What Is a Cast Iron Shower Pan?

A cast iron shower pan serves as the foundation for your shower. It has a cast iron structure and is covered in layers of enamel. Since it is two to three inches taller than the surface, it shields the water within so that it doesn’t spill out onto the floor and instead flows straight into the drain.

A cast iron shower pan’s enamel coating gives the floor a shiny, smoother appearance. In addition to being a very strong foundation, it serves as a waterproof barrier. 

Why Do You Need a Cast Iron Shower Pan?

#3 Unstable When Wet

The enamel coating undoubtedly provides the surface with a beautiful sheen, but it also makes the floor slippery when wet, and if you’re not careful, you could hurt yourself.

The flooring is heavy because it is made of cast iron, which is heavy. This means that the base must be very robust and durable in order to support the floor.
