Weight Range Of Cast Iron Bathtubs
Cast iron bathtubs are renowned for their durability and timeless charm. These iconic fixtures can be surprisingly heavy, with weights varying depending on their size and type. On average, cast iron bathtubs typically range from 240 to 500 pounds. However, it’s worth noting that factors such as style and configuration can influence the weight.
Here’s a breakdown of the weight range for different types of cast iron bathtubs:
- Alcove bathtubs: These bathtubs, designed to fit snugly against three walls, weigh around 320 pounds on average.

Load Capacity And Support Requirements For Cast Iron Bathtubs
The weight of a cast iron tub is a crucial consideration when designing a bathroom. Ensuring proper support for the tub and anyone using it is essential.
A standard 320-pound cast iron bathtub can hold up to 267 pounds of water when filled to its 32-gallon capacity. Therefore, the bathroom floor must be able to support a minimum weight of 587 pounds – 320 pounds for the tub and 267 pounds for the water.
Fortunately, most bathroom floors that are built to code can handle a live load of 40 pounds per square foot. This means that a 5×10-foot bathroom, for example, can support up to 2000 pounds. This provides ample support for the cast iron tub and additional fixtures.
