The floor drain is a key point in the bathroom. When choosing it, you must pay attention to many aspects. Here are some points to note when choosing a floor drain :1. Whether the drainage is smooth: The main function of the floor drain is to drain water. If the drainage is slow, a pool of water will accumulate after taking a bath or something like that, which will be very frustrating. 2. Whether the anti-odor effect is good: Another function of the floor drain is to isolate the odor from the sewer pipe from the indoor air. It should be noted that many floor drains on the market now claim to have anti-odor functions. Whether they really have such functions or if the effect is good depends on our own judgment, mainly looking at the structure and principle of the ground floor. 3. Whether it is easy to clean: The floor drain comes into contact with dirt all the time. Over time, it is inevitable that some dirt will accumulate. Therefore, the floor drain must be easy to clean; otherwise, it will affect the drainage speed over time. The last factor to consider is the service life of the floor drain, which is mainly determined by the material and principle.
