With too many different fabrics, forms, and sizes to choose from, choosing a bathtub can be difficult. This guide will help you consider the most common choices on the market and determine whether or not a cast iron bathtub is right for you. Since the invention of modern plumbing, enameled cast iron tubs have been in use. Thanks to their timeless beauty, outstanding longevity, and ease of upkeep, these tubs are still iconic today.
Furthermore, a cast iron bathtub is made of porcelain bonded with iron and then enamel-coated to resist chipping. As a result of the enamel coating, the bathtub is very durable and resistant to chipping. It is also resistant to scratches and heavy impacts due to its iron properties. Since cast iron retains heat naturally, this bathtub can maintain water temperatures for much longer, providing a more enjoyable bathing experience.

Features of Cast Iron Bathtubs
All of the cast iron tubs on our list weigh an average of 370.2 pounds. The standard does not include water. They would be much heavier than the traditional plastic tubs. As a result, you must determine whether or not the floor will accommodate the extra weight. If you do not confirm how much weight your foot can handle, we suggest getting an estimate from a local flooring firm.
Keep Yourself Warm for a Long Time:
Cast iron tubs are known for their excellent ability to preserve heat as compared to their plastic counterparts. Instead of minutes, consider hours.
Their increased weight translates to increased longevity. When you’ve built your cast iron tub, it will usually last years, if not decades, longer than cheaper plastic tubs.
The size of the tub has a significant impact on cost, especially for cast iron tubs. Purchasing a tub at the bottom end of the overall price point would result in a slightly narrower tub that might not be deep enough to lay down in. The average cost of a standard-size luxury tub is about $1500.
The expense is heavily influenced by the tub’s design. It is attributed in part to shifts in the target demographic for the pool—inlaid decorative accents and other style elements are more stylish. A tub’s architecture is expected to be more costly the more sleek and complex it is.
Finally, Cast iron tubs will be more expensive for high-end designers, while cast iron tubs will be less costly for more common, practical businesses. Custom and antique tubs are not included in this review. A quotation is needed to get an estimate of the cost of every custom project.
Cast iron would still be the main ingredient of any cast iron tub. On the other hand, cast iron tubs are often coated with an exterior substance for warmth and aesthetic appeal because bare metal is considered uncomfortable to sit on. From tub to tub, the material used to cover the cast iron may differ.
Fiberglass is the most demanding material used in low-cost tubs. Since it can be cleaned smoothly and has an appropriate cosmetic appearance, it is still considered a low-cost tub material. The insulating qualities of fiberglass appear to overshadow a cast iron pool’s benefits, rendering it controversial for those who are searching to make a significant investment.
Another typical material used for this purpose is acrylic. It has the same issues as fiberglass but is a little more durable. Enamel is the preferred material for high-end cast iron tubs, and it is widely advised that a homeowner not purchase a cast iron tub until they can afford to have it enameled.
Enamel is preferred because of its classic, seamless appearance and ability to disperse thermal energy from hot water equally. Enamel is often formed into aesthetically pleasing shapes around the tub’s sides or exterior. It is an unusual occurrence for any other kind of material.
Appealing to the Eye:
Cast iron tubs, particularly those with enamel coatings, are considered to be very attractive. When visible, the iron used in a cast iron tub is black and seems to be very strong. It offers cast iron tubs a long-lasting appearance that many homeowners admire.
A cast iron tub’s general nature is given further attention as a luxury piece. Only a tiny percentage of cast iron tubs are sold to take precedence over the shape. Cast iron tubs with filigree and other fine elements are more readily available than lower-end bathtubs.
Sturdy and long-lasting:
Cast iron tubs are best for their reliability and durability. Bathtubs, as fixtures, are typically very robust on their own. Rather than structural integrity, the most critical factors for replacing conventional bathtubs are incremental wear and tear or mold infection. The solid metal cores in cast iron tubs push things a step further.
They are practically impervious to internal injury, and the underlying metal’s strength makes it impossible for the enamel coating to be strained and cracked. Cast iron tubs are also highly resistant to mold and moisture since they have cast iron cores and few cracks in their overall structure. As a result, they are decent long-term investments.
Transfer of Heat:
Cast iron tubs have a distinct advantage in terms of heat transfer. When a bath is taken, it takes some time for a cast iron tub to heat up. Once the bathtub is loaded with hot water, it can remain hot for a long time, usually much longer than a regular bathtub.
A large amount of thermal energy is absorbed and retained by the metalcore. The water avoids losing power to the pool until it has warmed up, which can be a big issue in traditional designs for those who choose to take a long bath.
What is a cast iron bathtub?
Stability is one of its main characteristics. The cast iron bathtub is smooth to the touch with flat, crisp, clean lines. Its white finish is very bright.
Which material is the finest for a bathtub?
Metal: The most prevalent material used in bathtubs is cast iron. Steel is a durable and easy-to-maintain material. Steel is substantially lighter than cast iron and maintains heat better. Enamelled steel is hefty, but it’s also highly robust and heat-resistant.
What is better an acrylic or steel bathtub?
However, acrylic bathtubs are more sensitive to the appearance of stains due to the use of abrasive materials, in addition, the acrylic material is less rigid than steel. Also, due to their composition, they better retain the heat of the water. Finally, an aesthetic detail, they shine less than the steel ones.
How much does a bathtub weigh?
Weight: take into account that a bathtub with water and occupant (especially if it is hydromassage) can weigh more than 500 kg, which is important when installed on a higher floor.
