1. In addition to traditional bathtubs, many students now choose jacuzzi bathtubs. There are three types of massage bathtubs: whirlpool, bubble, and whirlpool and bubble combination, which should be clear when buying;
2. The bathtub materials are mainly acrylic, steel plate, and cast iron as mainstream products. Among them, cast iron is the highest grade, followed by acrylic and steel plate. As the absolute mainstream of bathtubs in the past, ceramics are almost invisible in the market;
3. The quality of the bathtub material mainly depends on whether the surface is smooth and the hand is smooth. Especially for steel plate and cast iron bathtubs, if the enamel is not well plated, fine ripples will appear on the surface;
4. The quality and thickness of the material are related to the firmness of the bathtub, and students can't see it by visual inspection. You need to press it with your hands and step on it with your feet. If there is a feeling of sagging, it means that the hardness is not enough. Of course, it is best to obtain the consent of the merchant before stepping on it.
