- Not Efficient Enough Against The Stains
Corian is generally resistant to staining. But, it is not wholly impervious to all types of liquids. Even CLASS I reagents like red wine, coffee, and oil can stain your sink.
Sometimes they are difficult to remove. Moreover, CLASS II reagents like paint remover and drain cleaners are strongly forbidden for Corian sinks.
These stains can be especially problematic if left untreated for too long. However, if you end up with a stain, you can use a mild abrasive cleaner and a soft cloth to remove it.
- Develops Cracks Over Time
Over time, Corian sinks can develop cracks due to various factors. Heavy objects being dropped on the sink, temperature changes, or simply wear and tear over time can cause cracks to form.
These cracks can be unsightly and allow water to leak out of the sink and cause damage to your cabinets and countertops.

- Color Fading Problem

Over time, Corian sinks can begin to fade or discolor, especially if they are exposed to direct sunlight.
This fading can be frightful and make your sink look older than it actually is.

While Corian is heat-resistant, it can still be damaged by high temperatures. Placing hot pans or pots directly onto your Corian sink can cause it to warp or discolor.
