① Look at the smoothness. According to the quality of the material according to the gloss of the surface, it is suitable for all bathtubs of one material.
②Press hands and feet to test the firmness. The firmness of the bathtub is related to the quality and thickness of the raw materials. It is estimated that it cannot be seen. You must try it yourself. Under the condition of force, for example, when you stand in it, do you feel that it will move down?
③ Touch the surface smoothness. It is suitable for thick steel plate and cast iron bathtub. Since these two kinds of bathtubs need to be plated with pond porcelain, the processing technology of plating is not very good, and there will be tiny wave patterns.
④ Listen to the sound. When purchasing a high-end bathtub, it is best to be able to “pass the water” and listen to the sound attentively when purchasing. If the motor noise of the surfing bathtub is too loud, you will not be able to enjoy it, but it will become a pressure.
⑤ Look at after-sales maintenance services. In addition to looking at product quality, well-known brands, and high cost performance, after-sales maintenance services are also a key factor that customers should consider, such as whether to provide on-site service for accurate measurement, after-sales service, etc.
