What is a Steel Bathtub?

Steel bathtubs, often called porcelain on steel tubs or enameled steel tubs, are made from a stamped steel shell that is later coated with a heat-fused porcelain enamel. This enamel coating allows the surface of the bathtub to be easily cleaned while staying glossy for several years. It also helps the tub be more scratch resistant.

What is a Cast Iron Bathtub?

Cast iron tubs are a classic tub design, dating back to the 1880s. Cast iron bathtubs are made with iron fused with porcelain, cast in the desired shape, that’s then coated in a layer of enamel to protect it from chipping and help make it easier to clean. Cast iron tubs themselves are naturally resistant to scratching and cracking.

How Do They Compare to Acrylic?

If your heart is set on a cast iron or enameled steel tub, then be prepared to pay the premium to purchase the tub and have it installed in your bathroom. You’ll have a classic, highly durable, heat-retaining tub that adds character, charm, and a luxurious bathing experience to any bathroom.

Remodeling your bathroom can be a great investment and provide a much-needed upgrade for one of the most-used rooms in your home. However, sometimes, the choices can feel overwhelming. For example, what type of bathtub should you pick?

Two popular bathtub materials are steel and cast iron. While both materials provide a luxurious bathing experience, there are a few essential differences to consider. We’ll break it down so you can make the best decision for your new bathroom.

Steel Bathtubs

Steel bathtubs are crafted from a stamped steel shell that’s later coated with heat-fused porcelain enamel, which is why they’re sometimes referred to as porcelain-on-steel or enamel tubs. The enamel coating allows the surface of the bathtub to be easily cleaned while staying glossy for several years and makes the tub more scratch-resistant. And since steel is a conductor, the bath water stays warmer longer.

Cast Iron Bathtubs

Cast iron baths are a classic tub design dating back to the 1880s. They’re made from iron fused with porcelain, cast in the desired shape, and then coated in an enamel layer to make them easier to clean. Cast iron tubs are naturally resistant to scratching and cracking.

The original cast iron tubs were freestanding clawfoot tubs. Many of the ones made today mimic those vintage designs, though they also come in more modern shapes.

Cast Iron vs. Steel Bathtub

Cast iron and steel bathtubs sound pretty similar, as they’re both made from metal. So, what are the key differences to consider?

How are Cast Iron and Steel Tubs Different?

So which is better, enameled steel versus cast iron tub? Many homeowners opt for the cast iron, many opt for steel—while others say that neither wins the cast iron tub versus steel tub debate and that acrylic tubs are the far superior bathtub type.

Cost

When purchasing a metal tub, you should expect to pay a bit more than you would for a standard acrylic tub. Steel and cast iron are highly durable materials, and this shows in their price tags. However, the cost is nearly the same for both types.

Installation costs should also be considered when choosing a bathtub. Metal tubs are very heavy and may require a reinforced bathroom floor before installation, adding to their overall cost.

Durability

Both enameled steel and cast iron tubs are long-lasting materials that naturally resist corrosion and abrasion. That being said, cast iron—as a thick, pure iron tub—is the most durable bathtub material. Cast iron tubs can potentially last for decades, longer than many other types of tubs.

Heat Retention

Both enameled steel and cast iron tubs retain bath water heat very well, allowing you to enjoy longer baths. Metals are great thermal conductors that naturally hold the water’s heat for an extended period of time.

Maintenance

Enameled steel and cast iron tubs are low-maintenance materials and, therefore, comparable in terms of maintenance. Both require regular cleaning (a gentle rinse of the tub) and may eventually need their enamel touched up to help the finish last longer.

Scratch Resistance

The enamel finish on both steel and cast iron tubs is resistant to scratching, chipping, and most chemicals. That being said, the enamel coating tends to be thicker on cast iron. Cast iron is also a more durable metal than steel, making cast iron tubs more scratch- and chip-resistant than steel tubs.

Weight

Cast iron tubs can weigh between 300 and 500 pounds, whereas enameled steel tubs tend to be around 150 to 200 pounds. In comparison, standard acrylic tubs weigh about 50 to 100 pounds. That’s why these metal tubs require extra floor support and may end up costing more overall.
