The plastic parts on showers, which were once bright white, can slowly fade to a dull yellow or cream colour after many years of use.

Alongside faults or wear, this is a common reason for replacing these parts!

Over time, exposure to UV (ultraviolet light) from sunlight, can cause a slow chemical reaction in the polymer (plastic). This can make your shower look old and tired. 

Why not spruce it up by replacing the parts rather than the whole shower?
