① Check the gloss. Examining the surface gloss helps determine the quality of the material and is suitable for bathtubs made of any material.
② Test the sturdiness by pressing with your hand and stepping on it. The sturdiness of a bathtub relates to the quality and thickness of the material, which cannot be determined visually. You need to test it yourself, such as by standing in it with weight; does it feel like it sinks?
③ Feel the surface smoothness. This applies to steel and cast iron bathtubs, as both require enamel plating. Poor plating can result in fine ripples.
④ Listen to the sound. When buying a high-end bathtub, it's best to "test the water" and listen to the sound. If the motor of a massage bathtub is too noisy, it will become a burden rather than an enjoyable experience.
⑤ Check the after-sales service. Besides product quality, brand, and cost-effectiveness, after-sales service is also an important factor for consumers to consider, such as whether on-site measurement and installation services are provided.
