This type of bathtub is durable and damage resistant but there are some things to keep in mind before purchasing a cast iron bathtub. As with any bathtub replacement, or even new tub installation, be sure to measure correctly. There's nothing worse than finding the perfect tub only to find out it doesn't fit. All tubs are various sizes so proper measurements are essential. The weight of a cast iron bathtub is an important aspect to consider. Cast iron is extremely heavy. This type of bathtub can weigh between two and three hundred pounds and up.

Keep in mind that the weight of the water needs to be factored into the weight of the tub. If the cast iron bathtub will be installed onto a lower level on a foundation, then weight consideration isn't often an issue. If there is a basement or the bathtub will be placed on an upper level of the home, it is important to seek a professional's service to ensure the weight will not be too heavy for the home's structure.

Aside from the weight of the cast iron tub, another point to consider is the plumbing. With many models of cast iron bathtubs, the plumbing is visible. The time of replacing or installing a new bathtub would be the perfect opportunity to replace old plumbing fixtures with newer ones as they will be easily seen once the cast iron bathtub is in place.

Bathtubs of cast iron typically run on the more expensive end of the price scale. When the price is compared to the durability, longevity, and even aesthetics of cast iron bathtubs, it can be well worth the money spent.
