Cast iron bathtubs are familiar to everyone, since this material was used for their production in Soviet times. Cast iron is a durable material with the property of retaining heat and absorbing sounds for a long time. The weight of the bathroom is about 120 kg, which can be regarded as a virtue, because you will not need to additionally take care of the fasteners. Reviews of cast-iron bathtubs are time-tested, because such products are available in almost every home. If you have experience using more modern bathtubs and you can compare them with cast-iron, please leave your opinion.
