Degree of wear
1. Observe whether there are obvious scratches, wear, or peeling on the surface of the seat. If the seat is made of plastic, the surface may wear and become rough after long-term use and friction. For example, frequent seat opening and closing or wiping with rough cleaning tools will accelerate the wear process. When the wear is severe enough to affect the smoothness and aesthetics of the seat, you may need to consider replacing it.
2. For seats with coatings (such as antibacterial coatings, self-cleaning coatings, etc.), check whether the coating has peeled off. If the coating peels off, the seat's antibacterial properties or self-cleaning functions may be affected, and bacteria are more likely to grow. At this time, replacing the seat is a better choice.
Discoloration
Discoloration of the seat is also an important reference factor. Long-term use, contact with chemicals (such as certain cleaning products), or direct sunlight may cause the seat to discolor. If the color of the seat becomes yellow, or black or has uneven color spots, it will not only affect the overall appearance of the bathroom but may also indicate that some changes have occurred in the material of the seat, such as aging or corrosion. At this time, you can consider replacing the seat to restore the neat appearance of the bathroom.
