Which bath fixture is known to be easily stained by smoke residue?

Fiberglass fixtures are particularly susceptible to staining from smoke residue due to their porous nature. When smoke occurs during a fire, the particles can settle on surfaces, and in the case of fiberglass, these particles can embed themselves into the material. This leads to the development of discoloration or staining that can be challenging to remove.

In contrast, porcelain fixtures are generally more resistant to staining thanks to their smooth, non-porous surface. Stainless steel fixtures, while durable, can suffer from surface markings or oxidation, but they are not prone to the same level of staining as fiberglass when exposed to smoke. Plastic fixtures can also be stained, but fiberglass has a reputation for absorbing smoke residue more readily, making it easier for stains to form and more difficult to clean effectively. Thus, fiberglass fixtures are recognized as significantly vulnerable to smoke staining.
