Know yourself and the enemy

Because the manufacturing material basically determines the performance of the bathtub, it is very important to determine the material you want when purchasing a bathtub. It is distinguished from the manufactured material. Generally, it is divided into acrylic cylinder, steel cylinder and cast iron cylinder. Different materials The bathtubs have their own different characteristics.

Comment: rich in shape, light weight, surface finish Good, and low price, but because man-made organic materials have the shortcomings of poor high temperature resistance, poor pressure resistance, non-wear resistance, and easy aging of the surface, the surface of the acrylic bathtub is rarely discolored after more than three years of use. However, some brand manufacturers use imported high-brightness and high-hardness special acrylic sheets for sanitary ware in their production, which overcomes some of the shortcomings of {TodayHot} acrylic to a certain extent.

Cast iron cylinder: made of cast iron, covered with enamel

Comments: High price and single style; heavy and difficult to move and carry, so the installation process is very troublesome, often requires hoisting, and it is difficult to move and repair after installation; its outstanding feature is good heat preservation performance. In fact, 90% of the heat loss during bathing is lost through the heat exchange and heat radiation between the water surface and the air, and only 10% of the heat is lost through the cylinder. In order to pursue the 10% heat preservation performance, it will cost more than buying other The material bathtub is nearly twice the capital.

Steel plate cylinder: a whole piece of bathtub special steel plate with a thickness of about 2 mm is formed by stamping, and the surface is then enamel treated.

Comment: It has the characteristics of heat resistance and pressure resistance, and its weight is between cast iron cylinder and acrylic Between the cylinders, the heat preservation effect is lower than that of cast iron cylinders, but this type of cylinder is not easy to adhere to dirt, wear resistance, and easy to clean.

Summary: The price of bathtub varies greatly due to the difference in material, color, shape, brand, etc. In the same brand, the most expensive is the cast iron bathtub, followed by steel and acrylic. However, it is difficult to compare the prices of bathtubs horizontally, and the prices of bathtubs of the same material vary greatly. According to the survey, the price difference of several acrylic bathtubs of the same brand also ranges from 700 yuan to 6,000 yuan. The price difference of different brands of acrylic bathtubs can be as large as 3000 to 5000 yuan. It is often the cheapest acrylic bathtubs of this brand that may be more expensive than the massage bathtubs of another brand.
