Cast iron bath - pros and cons, comparison with steel and acrylic bath, how to choose?

It would seem that this plumbing product is more than one hundred years old, but it still does not age and continues to hold its position in the market. What is the secret here? For many Soviet people, a cast-iron bath remains synonymous with reliability and durability, and these are the indicators by which newfangled acrylic counterparts lose significantly.

Pros and cons of a cast iron bath

Most are well aware of the advantages of this product, but it is worth reminding the uninitiated:

  1. The cast iron bath has a large wall thickness and low thermal conductivity. Yes, it will heat up longer than its metal counterpart, but it will also cool down more slowly, keeping warm for a long period of time.
  2. A cast-iron bath is produced by casting, and this method itself implies increased strength of the finished product. He is not afraid of any mechanical impact, falling heavy objects and even blows.
  3. Low noise level. If a person draws water into a metal bath, all household members will know about it, and a cast-iron one absorbs sounds well, which does not create inconvenience for others.
  4. Long service life. The product can serve its owner for decades without losing its qualities.

Among the shortcomings can be identified:

  1. A lot of weight, which in some cases can turn into dignity. Yes, a cast-iron bath is not easy to transport, and even harder to lift to the upper floors, because its weight can reach 170 kg. However, obese people feel more confident in such a tank due to increased stability.
  2. Reduced plasticity of the material, which creates obstacles for obtaining products of various shapes and designs.

Which bath is better — cast iron or steel?

This is easy to understand if you compare their characteristics:

  1. A bathing tank made of cast iron is heavier than steel. The latter material is lighter, more maneuverable and more comfortable.
  2. Steel allows the production of products of various shapes, so most of the design tanks are made of this material.
  3. The high thermal conductivity of steel is its main disadvantage. The water in such a bath cools faster than in a cast-iron one.
  4. The high level of noise produced by falling water in a steel bath remains a significant disadvantage for some and the choice in favor of a cast iron tank.

Which bath is better — acrylic or cast iron?

Recently, the plumbing market has been increasingly conquered by products made from acrylic — a relatively new synthetic material, called in Russian «plexiglass». Such a bath looks beautiful, besides, it can have a wide variety of colors and designs from classic to whimsical. Cast iron or acrylic bath is a question that many buyers care about. On the one hand, reliability and durability, and on the other hand, modern technologies.

The weight of a cast-iron bathtub far exceeds the mass of an acrylic one, so it is better to install it in private houses, and residents of high-rise buildings should opt for a lighter product. As for the rate of water cooling, both products demonstrate low thermal conductivity, and their strength is high. Some complain about the fragility of the acrylic tank, but the metal mesh at the base endows it with increased strength characteristics. It withstands a blow of even greater force than that inflicted on cast iron. However, the latter is easier to care for, but acrylic is more capricious in this regard.

If the acrylic is damaged, then removing the liner and replacing it with a new one will no longer work, you will have to buy a new bathtub.
