According to the material of manufacture, the most popular are cast iron, steel and acrylic baths.
Cast iron is strong and reliable, but imposes a restriction on a variety of forms, in addition, the weight of such a bath will withstand not every floor overlap. Steel is light, but it does not warmly maintain heat, which can greatly ruin the impression of water procedures. Acrylic baths are more beautiful, diverse in shape, design and color, but require more gentle operation.
