Which bath fixture is particularly prone to staining from smoke residue?

The bath fixture particularly prone to staining from smoke residue is fiberglass fixtures. Fiberglass surfaces can absorb and retain stains more readily than other materials. This is largely due to the porous nature of fiberglass, which can hold onto particles and residues like smoke, leading to visible discoloration. Over time, smoke residue can become embedded in these surfaces, making them more challenging to clean and restore to their original state.

While porcelain, metal, and vinyl fixtures can also be affected by smoke residue, they are generally less porous and more resistant to staining. Porcelain is relatively smooth and can often be cleaned more easily without retaining residues. Metal fixtures can reflect light and are usually more durable in terms of surface staining. Vinyl, while it can show discoloration, isn't as absorbent as fiberglass. Therefore, fiberglass fixtures stand out as being particularly vulnerable to the staining effects associated with smoke residue.
